I had 20/20 vision all my life until I was 27 years old. I first noticed a problem while driving at night. It seemed like I was experiencing double-vision. So I went to an eye doctor and was told that I was nearsighted. I don't remember what my prescription was but the doctor told me I would need glasses to drive, go to the theater or any outside sporting events.

Conventional prescription eyeglasses are very thick and they cannot be fitted to light weight trendy frames. So the frames were also thick. Totally, a thick eyeglass was worn by people with eyesight problems. They stand aloof from the fashion kings as thin glasses always look trendy. This isolation is now solved with the invention of use of high index plastic material to make lenses for prescription eyeglasses.

There are millions and millions of people throughout the world using prescription eyeglasses on a daily basis. Using these glasses has become a routine of their life. But it is not that all these million users have a comfortable and sophisticated working condition. There are many who have to work in fields and thus are exposed to large amount of pollution. These are people who need protective eye equipment. These workers have two options in front of them. They can either wear goggles over the other glasses or they can go for a pair of safety eyeglasses.

Macular degeneration is a medical condition predominantly found in elderly adults in which the center of the inner lining of the eye, known as the macula area of the retina, suffers thinning, atrophy and bleeding. This can result in a loss of central vision which affects the ability to see fine details, read, or recognize faces. Vision loss from macular degeneration involves much more than just a loss of visual acuity as follows.

Computer vision syndrome (CVS) is a group of eye and vision-related problems that result from prolonged computer use. Viewing a computer screen often makes the eyes work harder. As such, the unique characteristics and high visual demands of computer viewing make many individuals susceptible to the development of vision-related symptoms. The extent to which individuals experience visual symptoms often depends on the level of their visual abilities and the amount of time spent looking at the computer screen. Many of the visual symptoms experienced by computer users are temporary and will decline after stopping computer work.

Low vision is a term commonly used among eye care professionals to mean partial sight, or sight that isn't fully correctable with surgery, pharmaceuticals, contact lenses or glasses. Low vision can result from a variety of diseases, disorders, and injuries that affect the eye. Low vision can also be caused by heredity. Many people with low vision have age-related macular degeneration, cataracts, glaucoma, or diabetic retinopathy. Age-related macular degeneration accounts for almost 45 percent of all cases of low vision.
