Danger Of Contact Lenses And Eye Glasses
For modern times, the wearing of lenses has increase. The first contacts has been around since in 1887 and did but didn’t fit well and so was discarded. Another type of lens is made by Dr. Joseph Dallos in 1932 but it was fat being worn comfortably.
Plastic lenses made their appearance in 1943. These lenses were made to fit the outer surface of the eye ball and in 1948 corneal lenses came out. The corneal lenses were made to fit the cornea.
Many people are wearing corneal lens currently including children.
There are few eye-defects which contacts can help to correct. These are astigmatism (irregular sight), keratoconus (cone-shaped cornea) and high anisometropia (big difference in refractory powers of the two eyes).
In wanting to correct anisometrop with glasses, double vision will emerge.
Many peripheral areas of glasses will give rise to defects like spherical aberration, chromatic aberration and eye coma. But since contact lenses move with eyes it reduces the aforementioned problems.
It hasn’t confirmed that disposable lenses stop the advancement of eye-defect but alternatively expert claim that there are several dangers due to using lenses.
Here are a handful of dangers to using lenses.
1. Contact lenses are not entirely safe
2. Eyes may be contaminated with germs and micro-organisms if lenses aren’t well maintained.
3. Contact lens doesn’t allow atmospheric oxygen in the future in touch with cornea and so could cause corneal edema (water-logging).
4. The corneal might be injured as a result of wearing and removing eye lens.
Eye operation or surgery came in 1939. It was disastrous. But in 1969 a successful operation was over by way of a Russian doctor named Dr. achieve 70% success on 500 person. In 1972 another Russia doctor, Dr. Fyodorov perform 5,000 operations successfully.
What is conducted operational?
Eye operation is fairly simple. It includes 8 to 16 radial incisions for the cornea and is performed for individuals with short sight eye problems. These incisions flatten the corneal and send light rays that makes the individual sees clearly. Now the incision size and best contact solution
best eye drops for contacts position can cause complication and healing after the operation is an additional drawback. In conclusion, the will to get rid of glasses after operation is hardly achieved. Another problem with surgical treatment is those of fluctuation. The vision will take months to stabilize.
If glasses and contacts can destroy my Vision and surgical procedures are too risky, how can l then Improve attention sight?
The most important step would be to explore other options. Fix your daily diet, use proper nutrition, follow eye exercise preventing particular foods that affect eyes.
