Contact lens are generally thin and curved plastic
disks designed to cover the cornea which is the clear front covering of
the eye. Because of surface tension, the similar force that causes a
drop of water to cling to the side of a glass, makes contacts cling to
the film of tears over the cornea. It helps focus light entering the eye
onto the retina thereby giving clear vision. In simple words, contact
lenses are a sort of medical device worn by people which help in
improving our vision and makes us see more clearly.
Contact lenses can correct nearly every eye condition
like nearsightedness, farsightedness, astigmatism, presbyopia, and
alike. Also, people having good vision can use contact lens for changing
the color of their eyes in order to change their appearance and looks.
When used with proper care and supervision, contact lenses provide a
safe and effective way to correct your vision. Contact lens can be worn
by almost everyone, even babies with eye problems are fitted with
contact lenses.
One of the most important advantage of contact lenses is that they
provide better vision when looking at odd angles as there are no frames
to block side vision. Lens also helps in improving one's self image and
providing a better cosmetic look for those who don't like glasses.
This
advantage is particularly beneficial for people engaged in activities
like athletics and photography. Contact lens can be soft or hard one
which can enhance or change the color of your eyes as well. Most contact
lens are hydrophilic (made of water). Soft lenses are generally
manufactured from materials that allow oxygen to pass through them and
reach the surface of the eye.
People considering to wear contact lens should visit the doctor first
for their eye exam to determine the exact condition of their eyes and
the appropriate requirement for a particular type of lens as variety of
contact lens are available in the market. But sometimes contact lens can
be dangerous as it can damage your eye, if not used properly.
