For recent times, the wearing of contacts has increase. The first lens came into existence in 1887 and did but didn’t fit well so was discarded. Another type of lens was developed by Dr. Joseph Dallos in 1932 however it was overweight to be worn comfortably.
Plastic lenses made their look in 1943. These lenses were made to fit the outer surface of the eye ball as well as in 1948 corneal lenses arrived. The corneal lenses were made to fit the cornea.
Many individuals are wearing corneal contacts currently including children.
There are few eye-defects which contact lenses will help correct. These are astigmatism (irregular sight), keratoconus (cone-shaped cornea) and high anisometropia (huge difference in refractory powers of the two eyes).
In looking to correct anisometrop with glasses, double vision will emerge.
Many peripheral parts of glasses may give rise to defects like spherical aberration, chromatic aberration and eye coma. But since contacts move with eyes it reduces the above problems.
It have not confirmed that lenses stop the continuing development of eye-defect but rather expert state that there are some dangers arising from using lenses.
Here are some dangers to using lenses.
1. Contact lenses are certainly not entirely safe
2. Eyes might be contaminated with germs and micro-organisms if lenses aren’t well maintained.
3. Contact lens won’t allow atmospheric oxygen ahead in touch with cornea therefore may cause corneal edema (water-logging).
4. The corneal might be injured due to wearing and removing eye lens.
Eye operation or surgery started in 1939. It was disastrous. But in 1969 an effective operation ended by the Russian doctor named Dr. achieve 70% success on 500 person. In 1972 another Russia doctor, Dr. Fyodorov perform 5,000 operations successfully.
What is completed in operation?
Eye operation is very simple. It contains 8 to 16 radial incisions about the cornea and is done for those that have short sight eye problems. These incisions flatten

best contact solution the corneal and send light rays that makes the person sees clearly. Now the incision size and position could cause complication and healing following the operation is the one other drawback. In conclusion, the desire to discard glasses after operation is hardly achieved. Another problem with surgical procedures are those of fluctuation. The vision may take months to stabilize.
If glasses and contact can destroy my Vision and surgery is too risky, how do l then Improve my attention sight?
The most important step would be to explore other options. Fix what you eat, use proper nutrition, follow eye exercise which will help prevent certain foods that affect eyes.
