Contact lens rests on the cornea atop a permanent supply of tears. The pressure exerted from the eyelids while blinking also act as the support to hold the contacts in place. The pressure exerted by blinking make the contacts move a bit and glide over the cornea. This little movement allows tears, floating underneath, to smoothly flush the trash out which accumulates in the eyes.

That’s how contacts stay on your eyes, providing a crystal clear vision. But the way they fix the vision problem is a completely different ball game.

There are several kinds of vision problems faced by people but the major four are Presbyopia, Myopia or Farsightedness, Hyperopia or Nearsightedness, and Astigmatism.

The lenses for Myopia or Farsightedness are very thin in the middle but thick on the edges. This makes retina process the light rays properly.

The lenses for farsightedness are exactly the opposite – thick in the middle and thinner on the edges – resulting into sharp vision and comfort.

The basic technology is the same for all kinds of contacts – redirecting light to a particular point on the retina. The difference is in their making as they have to treat different eye problems and the shape of cornea differs in each problem.
