There are different types of contact lenses that are easily available in the market these days. Myopia is a common eye disease and with the advancement of medical science Myopia can be easily cured. Nearsightedness, or myopia, is a vision condition in which near objects are seen clearly, but distant objects do not come into proper focus. Nearsightedness occurs if eyeball is too long or the cornea has too much curvature, so the light entering the eye is not focused correctly. Nearsightedness is a very common vision condition that affects nearly 30 percent U.S. population. Evidences suggest that the theory that nearsightedness is hereditary. There is also growing evidence that nearsightedness may be caused by the stress of too much of close vision work like spending hours in front of the computer. It normally first occurs in school-age children. Because the eye continues to grow during childhood, nearsightedness generally develops before the age of 20. The Causes of Myopia and the signs of nearsightedness is difficulty seeing distant objects like a movie or TV screen or chalkboard.
To do away with it, a comprehensive optometric examination will include testing for nearsightedness. A good optometrist can prescribe eyeglasses or contact lenses to correct nearsightedness by altering the way the light images enter your eyes. One may only need to wear them for certain activities, like watching TV or a movie or driving a car, or they may need to be worn for all activities. Effects of Myopia can be disastrous if not done proper treatment at the right time.
Its been noticed that Myopia has become a infection of western society since the last 100 years, with significant increases over the last 1-2 decades especially amongst children. Recent studies indicate that in Singapore the rate of myopia amongst school kids is about 75%, up from about 25% just 30 years ago. In Israel between the years 1990 and 2002 the rate of myopia among school children increased from 20% to 28%. Amongst the Jewish Haredi male population the prevalence of Myopia has reached up to 80%. Myopia is much more common where one parent is myopic, and more common still if two of the parents have it. Accordingly, to meet the genetic make up of this particular disease, different types of Myopia are a very important factor. However, in this case, environmental factors are also crucial. AS its commonly seen that 70 per cent of 18-year-old men of Indian living in Singapore have myopia, while in India itself the rate is roughly 10 per cent. The same conditions are seen in Inuit and Pacific Islanders where myopia patients have gone up in recent decades.
