Contact lenses are generally used for two
common reasons. Some people use it for correcting their vision problem
and some use it for fashion purpose. Whatever be the purpose, the
popularity of contact lenses is rising high, leaving behind the
traditional eyeglasses. People using contact lens for fashion are able
to change the color of their eyes by using the typical colored lenses.
Whereas, people having vision disorder have jumped to contact lens as
eyeglasses provides a discomforting factor to their eyes.
Most of the times contact lenses are used for correcting the
vision disorder conditions that eyeglasses use to correct earlier. Some
of these conditions are:
A) Myopia or nearsightedness
B) Hyperopia or farsightedness
C) Astigmatism
D) Presbyopia
When the difference between the power of the left and right eye is more
than four diopters (eye power is measured in diopters) you may
experience double imaging while using corrective glasses but this
problem can be rooted out by using contact lenses. Contact lenses are
also recommended when the eye power is high because the corrective glass
used would be very thick resulting in reduced field of vision which
makes you unable to view the area on the side but this does not happen
while using contact lenses as they result in increased field of vision.
Sometimes,
contact lens also helps in preventing an increase in the power of the
eye. People with low eye power who are in to professions like acting and
modeling can also consider wearing contact lenses.
Contact lenses
can be worn by almost everyone however some conditions would not let you
wear the lens like frequent eye infections, severe allergies, dry eye, a
dusty environment and inability to handle the lens properly as all these
would result in to adverse effects to the eyes. Ultimately the need of
contact lens depends upon individual requirement and expectations.
