For modern times, the wearing of contact lenses has increase. The first contact lens has been around since in 1887 and did but failed to fit well and thus was discarded. Another type of lens was made by Dr. Joseph Dallos in 1932 however it was overweight to get worn comfortably.
Plastic lenses made their look in 1943. These lenses were made to fit the outer surface of the eye ball along with 1948 corneal lenses arrived. The corneal lenses were made to fit the cornea.
Many everyone is wearing corneal lens today 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 (massive difference in refractory powers of the two eyes).
In trying to correct anisometrop with glasses, double vision will emerge.
Many peripheral elements of glasses can provide 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 lenses stop the continuing development of eye-defect but instead expert state that there are a few dangers arising from the use of lenses.
Here are a couple of dangers to getting lenses.
1. Contact lenses usually are not entirely safe
2. Eyes could possibly 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 therefore could cause corneal edema (water-logging).
4. The corneal can be injured on account of wearing and removing eye lens.
Eye operation or surgery started in 1939. It was disastrous. But in 1969 a prosperous operation was over by 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 performed in operation?
Eye operation is pretty simple. It contains 8 to 16 radial incisions for the cornea and is done for those with short sight eye problems. These incisions flatten the corneal and send light rays that makes anybody sees clearly. Now the incision size and position could cause complication and healing after the operation is the one other drawback. In conclusion, the will to get rid of glasses after operation is hardly achieved. Another problem with surgical procedures are that relating to 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 my eye sight?

to do would be to explore other options. Fix what you eat, use proper nutrition, follow eye exercise and prevent food items that affect eyes.
