The development of new contact lenses is an important technological breakthrough and this branch of science is still expanding with tremendous growth. Contact lenses are a successful form of vision correction, used by approximately 90 million people worldwide. One of the challenging problems encountered by this community is Opacification or loss of optical transparency of the contact lens materials. The tear components like chlorides of sodium and calcium, phosphates, glucose, lipids, proteins etc., may interact and diffuse into the lens material. This will certainly bring about a change in...
