"Are contact lenses better than eyeglasses?"
Contact lenses are better than eyeglasses
for certain vision disorders like
shortsightedness, long-sightedness,
astigmatism and presbyopia.
In the field of sports people prefer it
because eyeglasses are hard to handle.
Some prefer it for its wider view.
Eyeglasses don't cover the sides.
Temperature, rain or perspiration does
not affect contact lenses. And lastly
people for the look factor buy contact
lenses. It is a fact that eyeglasses do
not look good on many faces.
But contact lenses also have
disadvantages such as:
1. The eye becomes drier than normal
2. Risks of eye allergy increase if the contact lenses are not handled properly.
3. It is not good for people with conditions such as diabetes.
Hence we can safely say that it is the condition
that decides whether eyeglasses or contact lenses are better. It also depends
on the user's personal choice.
Contact lenses float on the surface
of eye. There are two types of contact lenses. Soft lenses are made of very
soft water soluble materials, which take the shape of the eye when worn. We
can change these disposable lenses daily, after two weeks or once in a month
depending on the brand and material.
Hard lenses are produced from hard gas-permeable plastic and
it covers only part of the cornea. Today colored lenses are also available.
