Know about the different types of contact lenses available in the market today
by Steven Jones OwnerContact lenses are used for
vision correction as well as for the cosmetic purposes and are placed on the
cornea of the eyes. Earlier the contact lenses were made of glass and were
sclera lenses. Sclera lenses are basically large in diameter and cover the complete
sclera, the white portion of the eyes. Because of the size, shape and material
used, these lenses could only be worn for shorter period of time. But now with
advancements in technology, the lenses are made of soft materials that make
them comfortable to wear for even longer durations.
There are numerous benefits of
using contact lenses. If they are used for vision correction purposes,
they perform the same functions as the conventional glasses. But as opposed to
the glasses, contact lenses are almost weightless and invisible. Most
importantly, they are more comfortable than the traditional
spectacles.
In market, there are different
types of lenses available for both vision disabilities and cosmetic purposes.
Some of these are mentioned below:

hassles of regular care and maintenance of the contact lenses, then disposable

allowing the oxygen to pass through the eyes completely which prevents the eyes
from drying out. Unlike other disposable contact lenses, these require regular
cleaning and proper storage. With proper care, they can be worn for a stretch
of 14 hours.

be either worn for a period of 7 days or up to 30 days continuously. They allow
oxygen to pass easily through the eyes, keeping them comfortable in the eyes
for multiple days.

the wearer wants some change in their eyes’ color. Colored contact lenses come
in four varieties such as visibility tints, enhancement tints, opaque tints and
