Proclear Lenses: Excellent for Dry Eyes |

After a few hours of wearing contact lens your eyes tend to dry up and
you will feel scratchy. This happens because contact lenses are foreign
bodies lodged in your eyes, which is completely unacceptable to the
body. The body, therefore, reacts to its presence by fighting the
contacts with proteins and lipids, which builds protein deposits on the
contacts thereby creating friction and dryness.
In other words, the
user of the contacts finds himself caught in the battle between the body
and the lenses like an innocent civilian in the middle of a battlefield.
It is in order to circumvent this difficulty that proclear lenses have
stepped in. A substance called phosphorylcholine (PC for short) is found
naturally in the body. This substance is used to make biocompatible
lenses, which remain moist and dry throughout the day. They are
different from ordinary contact lenses primarily because due to the
presence of PC the body accepts them more easily and does not react to
its presence. In other words, despite being a foreign body, it does not
appear and feel foreign to the body.
Secondly, they preserve moisture and are, to a large extent, resistant to dehydration, which
makes them stay moist all day long. Besides, they also have a water
layer which bars the protein and lipid deposition.
Most of the itching and irritation in the eyes is caused due to protein deposition
which is a result of restricted oxygen supply through the lens. The
proclear lenses disallow the deposition, thus facilitating the supply of
oxygen. These lenses are an innovation in the field of contact lenses
and have so far been found to work to the utmost satisfaction of the
users. However, the comfort level may fluctuate among the users, which
means some may be more satisfied than the others.
So, if you are unhappy with your present contacts, you may consider switching to the
proclear kind, which might prove a boon right from the blues. It is,
however, recommended that before switching over you consult your eye
specialist so that he could advice you on the pros and cons of it.
