Contact lenses have quite a few characteristics that define them in particular
groups such as

or RGP and soft lenses.
• Wearing schedule of the lenses. FDA or Food and Drugs Administration
have approved few lenses for daily wear and others for extended wear.
• Replacement schedule of the contacts. The disposable contacts are very
popular and are disposed after a day’s wear or after a week or two or
after a month or after 6 months. These lenses are very safe for having
a healthy eye.
The contact lenses are even available in different colors like green,
blue and grey or brown. A special effect contact lens is also available
for theatrical use. They are of great fun only if prescribed by an eye
care professional. Never buy the lenses from a beauty parlor, never exchange
or share it with your friends. Always get a prescription from the doctor
before opting them. By law, you require a prescription to buy any kind
of contact lens. This rule prevails to ensure the security of your eye.
The doctor understands the requirement of your eye and thus can suggest
you with the right kind of lens. They will help you choose the right lens
for you.
Wearing or removing a contact lens is not a very difficult task. You
may be afraid initially but once you are acquainted with it, it will take
no time and difficulty in either wearing or removing them. You don’t even
need to fear of lenses getting stuck behind your eye. The presence of
a natural membrane blocks the lens from getting stuck. The membrane is
present at the back and front of the eye; therefore, lens getting stuck
behind your eye can never happen.
You have to take special care of the lenses. Regular cleansing and following
the fitting instructions of eye care practitioner must be followed. If
your lens gets torn or gets damaged or is lost then discuss it with your
doctor. With daily disposable lenses, you don’t have to worry about the
expense of buying a new one. You do this on the daily basis.
