These side effects can have serious medical consequences, and they occur in about 3% of men who take 25 – 50 mg, 50% of men who take 200 mg, and a staggering 100% of men taking 600 – 800 mg of the drugs.In addition to these side effects, there is also a very rare eye disorder that has been reported in several men using Viagra, Levitra, or Cialis, and is now under investigation to determine if there is a link between the medication and this poorly understood vision problem.This eye disorder is called Non-Arteric Anterior Ischemic Optic Neuropathy (NAION). NAION is the most common optic nerve disease that occurs in adults over the age of 50. In response to the possible link between NAION and medication like Viagra, Pfizer has stated: “Most of the cases in which NAION has occurred in men taking Viagra have involved patients with underlying anatomic or vascular risk factors associated with the development of NAION.” Essentially, this means that relationship between Viagra and NAION cannot be determined at this time.”The bottom line is, and what I tell all my patients, is that these medication should never be taken unless they are needed because there are serious health and visual risks associated with them,” says Dr. Lewis.If you are considering taking Viagra, Levitra, or Cialis, it is important that you check with your ophthalmologist before taking any of the drugs if you suffer from:§ Diabetes§ Retinitis Pigmentosa§ Retinal Pthology (Macular Degeneration or other Optic Nerve Disorders)VIAGRAWhat is Viagra?Viagra is an anti-impotence drug manufactured by Pfizer with an active ingredient sildenafile citrate for treatment of male impotence. Sildenafile citrate relaxes the muscles and increases the blood flow to particular areas of the body. The intake of Viagra increases the ability to achieve and sustain erection on being sexually stimulated. Men taking Viagra have reported an amplified sex drive, increased stamina, and quicker recharge. Viagra works together with sexual stimulation to help achieve maximum sexual satisfaction. However, Viagra does not guarantee protection from getting sexually transmitted diseases, including HIV and Hepatitis.How Viagra works?Viagra enables many men with ED to respond to sexual stimulation. When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the penis. As the arteries in the penis expand and harden, the veins that normally carry blood away from the penis become compressed, restricting the blood flow out of the penis. With more blood flowing in and less flowing out, the penis enlarges, resulting in an erection. It is to be noted that Viagra is not a hormone or aphrodisiac, it works only when a man is sexually stimulated.Viagra DosageViagra is available in the form of tablet and is meant to be taken orally. Ideally it is to be taken almost an hour before the sexual activity. However, Viagra can be taken anytime from 4 hours to 30 minutes before sexual activity. It takes 30 – 45 minutes for showing Viagra’s effect and this effect lasts for almost four hours. If you take Viagra after a high-fat meal (such as fish & chips, cheeseburger or French fries), it may take a little longer to start working. Viagra should not be taken more than once a day unless prescribed by your doctor.

Why Do Black Underwear Degenerate?

Black underwear is always very dignified and elegant atmosphere, just as there is always the smell of mothballs on festive dress.

If I put this kind of thing, my husband will ask: ‘how is it? Are you a prostitute?’” The sisiter of Mr A never knew her surprise brought how much pleasure to me. But disappointment followed. This disappointment is asked from myselves through my blind, caused from the intellectual research. I finally had to admit that my sexy black lingerie in terms is not worth mentioning. I read a rather negative reputation about the underwear industry of the French Eve • Yves Saint Laurent’s words: “during world war 1, only respectable woman can wear black underwear, it was a decent performance. And now (during the two wars) it was not considered whore clothes.

As Why the prostitutes choose black underwear, it is entirely a mystery to me. Black underwear is always very dignified and elegant atmosphere, just as there is always the smell of mothballs on festive dress. Clients who look for brothels in the places should search some unusual things that can cause sexual desire, not the dignified and elegant costumes. I found this answer which bothers me for many years until much later of that.

People who answer my question is a blonde I met in Zurich hotel.She was tall and well-proportioned stature, dressed in mink shawl, slightly hoarse voice, crossing a pair of awesomeness long legs.She talk to me,at the same time smoked Camel cigarettes.At that time I had to visit the woman called Ms L because of my work. Under the condition of keeping secret in good (of course, only talking about it, because she had leaked her true identity which is actually the Baroness).In order to take account of certain elders, her name must be kept confidential. L are still the world’s most expensive Mama Sang until today, although she was neither maternal nor brothels. However, after careful consideration she took over the popular “cause.”legendary Mrs. Claudette Colbert had did in Paris.

In order to understand how L was highly positive, and how the smart brokers and hearted people have the credibility. How to win the love of ladies who she’s working on, of course I’ll have to talk to them. The cost of them is between 1500-2000 U.S. dollars per night,and “additional services” are not included. They are all daughters came from good people and the most expensive lady came from the upper nobility,who is the most popular young lady. Her usual job is auction company’s senior sales staff in London.

This is a disease of the older generation. One that I had not heard of before my father started showing signs of it. Taking ample amounts of omega 3 may prevent it.

It is a progressive disease that affects your center vision. Centre vision is required to be able to read and drive. The people suffering from this disease need to give up driving, and need a special magnifying glass, which lights up in order to read.

The disease can affect one or both the eyes. It is one of the main cause of blindness in the people who are over the age of 60.

People who are aware of this disease, shudder with fright as they approach 60 years of age. As I am searching for help for my father, I am also aware that the disease is hereditary. You need to look for ways to prevent this disease catching up with you in the later stages of life.

Taking omega 3 supplements in the early ages could help to prevent this disease in the old age.

The macula tissue is present in the middle of the retina. The retina is sensitive to light. The retina’s job is to change light or pictures into electrical impulses and send them onto the brain.

Macular degeneration are of two types.

The first one is known as wet macular degeneration. It is caused by the abnormal growth of the blood vessels behind the retina. The blood vessels are very delicate and can possibly let blood or fluids leak out. This makes the macula to rise out of the normal spot at the back of the eye. When this happens, the damage to the macula is rapid.

The blindness that sets in rapidly, is known as as Advanced Macular Degeneration.

You can watch for early symptoms of AMD by using a chart. This chart has intersecting lines on it. It sort of looks like graph paper. There is a dot in the middle of each intersecting line. If these lines appear wavy as you test them with each eye, covering each eye one by one, then you need to see your eye specialist right away.

The second type is dry AMD. The dry type starts when the light sensitive tissues in the macula slowly break down. Your central vision slowly becomes blurred. As the dry AMD worsens, a blurry spot appears in the central vision. With the passage of time condition gets worse, you could loose your sight in the affected eye.

Drusen is the earliest symptom of AMD. Drusen can be diagnosed by the eye doctor in a routine eye examination when they dilate your pupils. They are yellow spots found under the retina. It is normally found in people over 60 years of age. If there is an increase in the number of these yellow spots or their size, it’s a sign of them possibly developing either type of the AMD ending in loosing sight.

Apart from age, the other risk factors for developing AMD are:

Smoking
Obesity
Race
Family history and gender.

Changes in your lifestyle that could make a difference are:

Eating a good diet of green leafy vegetables and fish
Keeping your blood pressure under control
Maintaining a healthy weight
Regular Exercise. And definitely don’t smoke.

Another change in lifestyle, you could adopt could be to add more Omega 3 to your diet. As mentioned above, include fish in your diet. Not everyone enjoys eating fish. There are a variety of ways to get Omega 3 and a good way to know you are getting enough is to take supplements.

My father is almost blind now. I hope that the disease does not progress any further. We have put him on Omega 3 supplements hoping it will stall the disease. Only time will tell. As for others, try to prevent it before it happens to you.

Broccoli is a good source of vitamin A, vitamin E (alpha-tocopherol), Thiamin, Riboflavin, Pantothenic Acid, Calcium, Iron, Magnesium, Phosphorus and Selenium, and also has good Dietary Fiber, Vitamin A, Vitamin C, Vitamin K, Vitamin B6, Folate, Potassium, Manganese and good antioxidant properties.

Broccoli has twice as much vitamin C of an orange, as much calcium as whole milk, and has better absorption of calcium. It also contain selenium, a mineral found to have anti-cancer, anti viral properties.

The phytonutrients, sulforaphane and the indoles, contained in broccoli have significant anti-cancer effects. Proven by research (indole-3-carbinol) helps deactivate a potent estrogen metabolite that promotes tumor growth, especially in estrogen-sensitive breast cells, simultaneously increasing the level of 2-hydroxyestrone, which is a form of estrogen that can be cancer-protective. Not only Indole-3 carbinol can suppress breast tumor cell growth, but also cancer cell metastasis (the movement of cancerous cells to other parts of the body.

Sulforaphane contained in broccoli offer special protection to those with colon cancer-susceptible genes.

Broccoli sprouts contain 10-100 times the power of mature broccoli to boost enzymes that detoxify potential carcinogens! A healthy serving of broccoli sprouts in your salad or sandwich can offer some great health benefits.

Broccoli helps significant reduction in heart disease risk, cataract prevention, boost our immune system, build stronger bones because of the folic acid presence. Deficiency if folic acid is the world most common vitamin deficiency.

Broccoli not only is a rich source of vitamins, it also has both insoluble and soluble fiber which our body need. Botanically, broccoli belongs to the cabbage family, collectively know as cruciferous vegetables, which health organizations recommend a must-have foods several times a week, because they lower the risk of cancer.

Listed below are 10 health benefits of broccoli.

Nervous SystemBroccoli contains a high amount of potassium, which helps maintain a healthy nervous system and optimal brain function, as well as promotes regular muscle growth.

Blood PressureAlong with a high amount of potassium, Broccoli also contains magnesium and calcium that help regulate blood pressure.

Vitamin COne cup of broccoli contains the RDA of vitamin C, an antioxidant necessary for fighting against free radicals. Moreover, vitamin C is an effective antihistamine for easing the discomfort of the common cold.Bone Health Broccoli contains high levels of both calcium and vitamin K, both of which are important for bone health and prevention of osteoporosis.

Sun DamageBroccoli is helpful in repairing skin damage thanks to the glucoraphanin it contains which helps the skin to detoxify and repair itself.

Immune SystemOne cup of broccoli bolsters the immune system with a large dose of beta-carotene. Trace minerals, such as zinc and selenium, further act to strengthen immune defense actions.

CancerBroccoli contains glucoraphanin, which with the body processes into the anti-cancer compound sulforaphane. This compound rids the body H. pylori, a bacterium found to highly increase the risk of gastric cancer. Furthermore, broccoli contains indole-3-carbinol, a powerful antioxidant compound and anti-carcinogen found to not only hinder the growth of breast, cervical and prostate cancer, but also boosts liver function.

Diet AidBroccoli is high in fiber, which aids in digestion, prevents constipation, maintains low blood sugar, and curbs overeating. Furthermore, a cup of broccoli has as much protein as a cup of rice or corn with half the calories.

VisionStudies have shown that the carotenoid lutein helps prevent age-related macular degeneration and cataracts, as well as possesses anti-cancer effects. Additionally, broccoli is a good source of vitamin A that is needed to form retinal, the light-absorbing molecule that is essential for both low-light and color vision.

Heart DiseaseThe carotenoid lutein may also slow down or prevent the thickening of arteries in the human body, thus fighting against heart disease and stoke. The B6 and folate in broccoli also reduce the risk of atherosclerosis, heart attack, and stroke.

Diabetes mellitus or diabetes is a disorder that springs from excessive glucose or sugar levels in blood. The hormone insulin secreted by our pancreas breaks down the glucose obtained from the food we consume, and enable it to enter body cells. This is a metabolic process energizing our body. When there is a dearth of insulin in the body or body cells become resistant to insulin, glucose collects in blood and the levels rise, leading to diabetes. Among the several types of diabetes, Type 1, Type 2 and gestational diabetes are quite common.

Type 1 occurs due to inadequate supply of insulin, Type 2 occurs due to cells becoming non-responsive to insulin, and gestational diabetes is a type that occurs in women during pregnancy. Other types include congenital diabetes, steroid diabetes, monogenic diabetes, cystic fibrosis related diabetes. Heredity, stress, smoking, alcoholism, lack of physical activity, and obesity are factors contributing to diabetes.

Diabetes should be checked in time, or else it may be fatal leading to cardiovascular diseases, renal failures, retinal damage and neuropathy.

Symptoms

1. Frequent urination
2. Increased hunger
3. Increased thirst
4. Constipation
5. Fatigue
6. Weight loss
7. Pale yellowish, sweet odorous urine
8. Blurred vision
9. Slow-paced healing of wounds
10. Irritability

Best way to prevent diabetes

It is advisable to seek medical help once diabetes has attacked a person. Doctors often prescribe medicines to maintain a balanced glucose level in blood. The target is to avoid hyperglycemia or too high levels of glucose and hypoglycemia or too low levels of glucose in blood, and keep it close to normalcy. Insulin therapy is suggested for type 1 diabetes, and for type 2 diabetes, oral pills like Metformin, Sulfonylureas, meglitinides, alpha-glucosidase inhibitors etc are prescribed. Herbal supplements like Diabkil capsules, bitter melon capsules, gurmar churna, etc making use of pure herbs like neem, basil, blueberry, bitter gourd, cinnamon, milk thistle, ginger, garlic etc can run simultaneously and keep blood sugar under control. They are safe and purely herbal.

Prevention however is better than cure, and so to avoid diabetes it is best to adopt a healthy way of living. Diabetes can be prevented by moving away from sedentary lifestyle, inculcating healthy habits, dietary changes, control of body weight through increased physical activity.

The preventive measures given in this article will surely help you to prevent diabetes effectively and keeps your blood sugar to the normal levels.

Biometric security software may be familiar with you as you see in any number of futuristic movies. The use of voice identification, fingerprints or retinal scans to gain access into a building or to use a computer might seem futuristic. In fact, the technology has already existed and has been used for over a decade.

It is not currently in widespread use, which is why it seems to fit in the movies. Many people are unaware of it. A lot of companies still rely on guards or keypads and passwords to secure their buildings.

According to the private consulting firm of Booz Allen, the technology has been used by the federal government since at least 1995. There is even some controversy concerning its use in terms of personal privacy and civil rights.

So while it might be emerging or still developing in some ways, the technology is not science fiction.

It exists and can be used by your company.

The technology can be used to secure an entire building or a single room within the structure. It can and is being used to restrict access to company computers.

Vehicles can be equipped with scanners that allow only certain individuals to drive them. One of the instances that provides some support for the controversy occurred when a man’s finger was cut off by car thieves in order to get around the car’s security system. That happened in Malaysia in 2005.

In most cases, biometric security software has been a successful crime deterrent. There may be ways to get around it.

But, it is the best system currently available.

If you wanted to protect your employees, copies of their fingerprints can be integrated into an RFID tag. As with other kinds of tags, they could be stolen. But at least, your employees might be protected from injury during a robbery.

Biometric security software can also be used simply to confirm an employee’s identity. That could be important in a very large company.

Governments around the world are already using the technology in their “e-passports”. Many countries have announced plans to implement the technology in the future.

Cards can be used to store all kinds of personal information. Medical conditions are examples of information that can be stored on the identification cards. This is very helpful in emergency situations.

Walt Disney World is currently the largest commercial organization to make use of biometric security software. Regardless of your company’s size, you may find it useful, too. All that you need is a well-designed database.

A biometric security system is designed for security and access control applications. This device is used to measure or identify physical characteristics of a person which can be checked on an automated basis. This device can identify your behavioral trait, iris and retinal scan, fingerprints patterns, hand geometry, facial characteristics, voice prints, hand written signature and DNA sequence characteristics to determine your identity.

Today you can find this system in any common places as it is now offered in pretty affordable price. For future identification or verification purposes, there is some process, sort of an enrollment, by which the biological information is taken and stored in a database.

This method is considered as the most reliable identification among others since this system relies on biological information about a person. Then Seenex, as a reliable company in providing security system since 2001, produces a biometric security system with those types of identification. This company provides a proven security system for both homeland and international critical infrastructure (CIS) needs. As we have mentioned slightly above, now we are discussing several types of biometric security system for further.

Starting with fingerprint recognition, you might be interested to know what it is actually. This method of identification becomes the most used by which the verification is gained from the impressions made by unique ridges and valleys on the surface of a human’s fingertips. Second identification, facial recognition is used to analyze particular facial characteristics. This method identifies the length of the nose, the angle of the jaw and the distance between your eyes. Facial recognition is usually applied for surveillance process.

A biometric security device can also identify hand geometry which is based on the measurement of the shape of your hand. It is different from fingerprints identification. Hand geometry method is applied to identify width, length, and height of your fingers, or the distance between your joints.

Voice recognition is commonly applied to identify a person based on the various characteristics in his or her voice. This identification includes pitch, tone, cadence, and so on. Firstly, the device will capture samples of your speech and change it to an electronic format to create a biometric template.

The next method, biometric security device can recognize your iris for identification. This method is usually used for access control into a facility. The recognition is gained by analyzing the distinctly colored ring which surrounds the pupil of eyes. Iris is considered as a part of human body which will not change just like any other physical characteristics would change by age. It is also believed that there are more than 250 unique characteristics.

In addition, Seenex supplies complete secure access control, including designing, installing, and updating the system with innovations, and also training its clients. Seenex also provides other products on security system, such as access control portal systems, visitor management systems, surveillance systems, explosive/chemical detection, metal detection, and smart card technologies.

For overall, Seenex has become a trusted company in providing security system series. Thus we recommend you to consider their products when you are looking for those devices, especially a biometric security system.

In hot summer days, we always have to wear sunglasses to protect our eyes. But if the sun doesn’t bother my eyes, are you necessary to wear sunglasses? Obviously, the answer is yes! The sun has damaging UV (ultraviolet) rays that can cause photokeratitis, pingueculae and permanent retinal damage.

Let’s have a clear idea of UV rays. UV Ultraviolet (UV) rays are located just past the violet portion of the visible light spectrum; sunlight is the main source. UV light is broken into three different types: UVA, UVB and UVC.UVA has longer wavelengths and passes through glass easily; experts disagree about whether or not UVA damages the eyes. UVB rays are the most dangerous, making sunglasses and sunscreen a must; they don’t go through glass.

UVC rays do not reach the Earth because its atmosphere blocks them.

Most people think that they’re at risk only when they’re outside on a sunny day, but UV light can go right through clouds, so it doesn’t matter if the sky is overcast. The sun’s rays are strongest between 10 am and 2 pm. Glare and reflections can give you trouble, so have your sunglasses ready if you’ll be around snow, water or sand, or if you’ll be driving (windshields are a big glare source).

You must wear sunglasses to prevent damage to your eyes. While some contact lenses provide UV protection, they don’t cover your whole eye, so you still need sunglasses. Look for sunglasses that protect you from 99 to 100 percent of both UVA and UVB light. This includes those labeled as “UV 400,” which blocks all light rays with wavelengths up to 400 nanometers.

Since sun damage can occur regardless of the season or weather, and the effects are cumulative, wearing sunglasses everyday is important.

Sunglasses are significant for each of us to our eye protection.

Technically, there is no prescription wrinkle cream. There is an acne medication that eventually obtained approval by the US FDA for the treatment of wrinkles. It goes by various names. Retin-A is one example. Guess what it really is?

It is really the animal form of vitamin A; retinol. It is highly concentrated, always causes redness, usually causes itching and always increases your sensitivity to sunlight. Plant extracts that contain vitamin A are non-irritating and over the counter creams that contain it have been shown to be just as effective as Retin-A, without the side effects.

It makes sense, when you think about it. Things that are toxic to the inside of your body usually cause redness and itching of the skin. The animal form of vitamin A is toxic at high doses. It can even cause death. The A vitamins that exist in plants are known as carotenoids, including beta-carotene.

The body converts them to vitamin A on an as-needed basis. There is no way to get too many carotenoids in your diet.

So, instead of a prescription wrinkle cream containing retinol, look for an over the counter product that contains Shea butter or Avocado oil, plant-based sources of vitamin A. The vitamin is important to the skin’s health. Deficiency in the diet causes excessive dryness. So, eat your carrots.

Shea butter and avocado oil are also effective moisturizers. Many people buy dozens of anti-aging products, but overlook the power of a simple moisturizer. Moister skin simply looks better. Fine lines and wrinkles are far less noticeable. Avocado has an added benefit. One study showed that it increased the amount of soluble collagen present in the skin.

Normally, as we age, fewer collagen fibers are produced. The fibers are composed of soluble or tropo-collagen. The reason that avocado oil stimulates the production of tropo-collagens is unknown, but it is likely due to all of the antioxidants it contains. Antioxidants, of which vitamin A is one, are the most potent anti-aging ingredients that we have.

In a few years, there may be a prescription wrinkle cream that contains Idebenone, a synthetic version of the antioxidant coenzyme Q10. It has been shown to reduce roughness and dryness, while decreasing lines and wrinkles. There are already over the counter products that contain natural coenzyme Q10. The ingredient to look for is NANOLIPOBELLE COQ10.

It’s not the ingredient that will be used in the prescription wrinkle cream, but like the prescription version of vitamin A, that one is likely to be accompanied by unwanted side effects. NANOLIPOBELLE COQ10 is not accompanied by any unwanted side effects. It was created using “nanotechnology”, which allows the manufacturer to reduce the molecules in size to a point where they can be readily absorbed into the skin’s layers.

Typically, you will find NANOLIPOBELLE, Shea butter and avocado oil in night creams, because that is when the body repairs damage. Those three ingredients will work as well as, if not better than any prescription wrinkle cream that is on the market now or will be in the future.

The macula is a very small spot in the center of the back of the eye (retina) that sees clear, colored vision. The other part of the retina is composed of rods that see movements. So it can be pretty scary if a hole develops in this part of the eye. Aside from a blurry vision, macular holes can also affect night vision and peripheral vision.

Macular Hole Surgery are more likely to develop in people around the age of 60. Holes in the macula can occur due to vitreous shrinkage and/or separation, eye injury or a detached retina. Although the development of macular disorder is yet to be determined, it most likely occur from the vitreous.

A vitreous is a gel like material that fills the back of the eye. Also called the vitreous body, this helps keep the eye its shape.

However, the vitreous shrinks with aging. As it shrinks it can pull on the retina, referred to as a hole.

If macular hole is untreated, it can get worse over time. In some cases, macular hole can be fixed sometimes without intervention. However, in most cases, it requires treatment to avoid total loss of vision.

A vitrectomy is a common treatment for macular holes. This Macular Hole Surgery is done by removing the vitreous gel to stop it from pulling on the retina. Then a retinal specialist inserts air bubbles and gas into the space once occupied by the vitreous allowing the macula to heal. The bubbles gradually fades over time and natural eye fluids will take its place.

The surgery itself is easy but the post operation period can be tough. The patient must lie face down for days so that the bubble stays in the right place in the eye. Traveling by air is also not an option as the changes in pressure can cause eye damage.

Remember that most of the patients are not worried about the process of doing the surgery, but the post-surgery effects it can cause. Although the removal of the gel will fix the problem for the macular hole, it heightens the risk of developing other eye problems such as cataract.

Common risks of this surgery include retinal detachment and infection or even high grades of cataract development. Infection and retinal detachment are treatable and cataracts can be removed once the eye has healed. However, most of the patients who went through several eye surgeries develop the types of cataract and eventually led to blindness and other serious eye defects.

These are just some of the things that we should know about eye treatments. There is always a complication in every surgery. The positive side of it might be clearer vision and removal of the defect. However, there are things that we cannot avoid such as the aftershocks, should I say.

After the surgery, it is very beneficial to follow the medications religiously and make sure that the recovery guidelines are being observed. In this way, we can lessen the greater risk of acquiring other complicated eye defects that might lead us to total loss of vision.
