Polarized sunglasses are also used by people engaged in sports and even driving. But are there any differences between polarized sunglasses and ordinary ones?

Ordinary sunglasses work with the function of cut some amount of the lights. Because the ordinary lenses can’t filter lights, they just reduce the intensity of glare and ultra violet radiation, and can not completely block these harmful rays, so its function is to reduce eye injury.

A cataract is a clouding that develops in the crystalline lens of the eye or in its envelop, varying in degree from slight to complete opacity and obstructing the passage of light. If not treated timely, it may degenerate into incapacity in viewing, that is blindness. Therefore, when you find you are a cataract patient, going for the doctor and undergoing a surgery is a wise decision. To treat cataract, the clouding lens should be removed and a new one should be implanted.

There are formerly two types of eye surgeries that can be used to remove cataract: extra-capsular and intra-capsular. The former one is to remove the cataractous lens and replace with a plastic one while the latter is to remove the lens but leave the majority of the lens capsule intact. Recently a technique called phacoemulsification is applied in the cataract surgery. One of the biggest advantages is that during the procedure, a minor incision will be created to break the clouded lens into small pieces. These pieces are emulsified and sucked out by same ultrasonic probe. A thin outer shell still covers the eyes after the pieces are sucked out. And foldable artificial lens which is made of silicone or acrylic is inserted. This is done by using a proprietary insertion device. This incision does not require stitches and seals by itself.

Usually, before a surgery starts, the doctor will ask the patients to choose proper lens that will be inserted. Monofocal lens is for distant vision assistance, and for close vision, the patients has to wear reading glasses. However, new technology brings about focal lenses and multi lenses that are able to hand distant, near and in between vision. That is to say, with those lenses implanted, the patients would get a clear vision again.

The whole procedure will be done with a local anaesthetic, so the patients would feel no pain, and they can go home in about two or three hours after the surgery. Phacoemulsification is now considered to be an ideal way to treat cataract.

There is another method of surgery called extracapsular surgery which is on its way out. In this method the incision would be 8 to 10 mm and requires stitches. And patients are prone to distortion of the curvature of the cornea, resulting in astigmatism.

To know the Age-related macular degeneration(AMD) well, let’s have a general idea of the macula first. It locates in the center of the retina, which converts light or an image into electrical impulses and then sends these impulses, or nerve signals, to the brain. Therefore, we may know macular plays a fairly important role in viewing. Then age-related macular generation is an eye disease associated with aging that gradually destroys sharp, central vision, the macular. There are two different types concerned, the wet ones and the dry ones. The former is a less commonly seen condition. Wet eyes may quickly develop into blindness, because rightly after the blood vessels behind the retina start to grow, they are very likely to get ruptured. The latter is featured with blurred vision and sensitivity to light. With treatment, it is reversible.

In spit that AMD is age related, however, there are ways to prevent its degeneration and even occurrence. Therefore, having a healthy life and diet style is rather important. Tobacco is one of the arch-criminals of the development of AMD, so to keep away from tobacco is necessary. Eating more fruits and vegetables should be on your dinner table everyday. In addition, salt-water fish and leafy green vegetables are most recommended, for they perform well in AMD prevention. Lack of exercise and obesity are two risk factors contributing to AMD. Besides, to guarantee eye health, regular eye examinations should be taken. They could help in avoiding the worst symptoms of macular degeneration.

If you unluckily suffer from AMD, don’t worry, there are devices which would help in viewing in daily lives. Bioptic glasses are one such device. With miniature telescopes mounted on, the patients are able to concentrate on activities that require acute close central vision. Bioptic glasses work similar to the bifocals we know. For those patients who have a requirement to work with computers, another device, a special monitor that magnifies on-screen font sizes is ideal choice. Wearing them on, the patients are thought to be able to read more easily.

AMD is not terrible. Once you find hard to read, watch TV or do other routine activities, go for an eye doctor immediately. They are always there providing your treatments and advices. Moreover, the National Eye Institute is conducting and supporting a number of studies to learn more about AMD. It is believed that more progresses on treatments for AMD will be achieved.

Eyes are to view objects, however, it is not a born in ability. Our eyes have to learn how to function. The infancy period is a formative time when the infant’s neurological system is very flexible, and can easily adapt to changing environment stimuli. It is during such a period of time our eyes get visual stimuli and learn how to view. If any one of the eyes can not get adequate visual stimuli, amblyopia eye or lazy eye that we usually refer to could be developed. Amblyopia is a kind of eye disease whose symptom is reduced vision.

As one grows when his/her flexibility of the visual system decreases, it hard for him/her to improve the eyesight dramatically. In the past, the doctor would advise the patients to let the lazy eye work harder by patching the better eye, so that the visual function of the lazy eye can be stimulated. Nevertheless, if the patient is young enough, it may in some degree works. that is to say, it serves little when one reaches a certain age. Vision Therapy(VT) is also applied to retrain the visual system to function correctly. Most people would get their vision improved as long as VT is done properly.

Recently, researches find that the antidepressant medication Prozac is able to restate ocular dominance plasticity in adulthood. Such a discovery brings hopes to older individuals who want to promote their visual impairment, resulted from lazy eyes. Such an issue has ever been published in the Science Magazine, reading that Prozac, a kind of antidepressant medication reopens the critical period of plasticity in the visual cortex, and Lateral Geniculate Body parts of the brain. The Prozac achieves it by reorganizing the neuronal connections in the cortex. In the Magazine, the researches have also explained the possible side effect of Prozac’s performance in lazy eye treatment. They should be originated from the long use of drugs, including suicide, severe anxiety, glaucoma and visual filed defects.

Up to now, this study has been only proved to effective in the rats experiments, so further experiments on human being should be done to make sure its effectiveness. Therefore, long term research needs to be done to determine the risk and benefits of such treatment, and improved should be necessarily made.
