Danger Of Contact Lenses And Eye Glasses
For the past few years, the wearing of lenses has increase. The first contact came into existence in 1887 and did but didn’t fit well so was discarded. Another type of lens is made by Dr. Joseph Dallos in 1932 however it was fat to be worn comfortably.
Plastic lenses made their appearance in 1943. These lenses were made to fit the outer surface of the eye ball along with 1948 corneal lenses became available. The corneal lenses were made to fit the cornea.
Many people are wearing corneal contact lens these days including children.
There are few eye-defects which disposable lenses may help correct. These are astigmatism (irregular sight), keratoconus (cone-shaped cornea) and high anisometropia (difference in refractory powers of the two eyes).
In attempting 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 lenses move with eyes it reduces these problems.
It hasn’t confirmed that lenses stop the progression of eye-defect but instead expert state that there are a few dangers arising from using lenses.
Here are a couple of dangers to presenting lenses.
1. Contact lenses are not entirely safe
2. Eyes could possibly be contaminated with germs and micro-organisms if lenses are certainly not well maintained.
3. Contact lens does not allow atmospheric oxygen in the future in touch with cornea and thus might cause corneal edema (water-logging).
4. The corneal might be injured due to wearing and removing eye lens.
Eye operation or surgery arrived 1939. It was disastrous. But in 1969 an effective operation was over with 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 in operation?
Eye operation is quite simple. It includes 8 to 16 radial incisions for the cornea and is conducted for those with short sight eye problems. These incisions flatten the corneal and send light rays that makes the person sees clearly. Now the incision size and position may cause complication and healing following your 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 regarding fluctuation. The vision will take months to stabilize.
