Purchase Contact Lens Washer

Why contact lenses?
According to a recent study, millions of American have now switched to contact lenses from eye glasses. One of the major reasons why contact lenses are immensely popular is the convenience they provide. They are light weight, virtually invisible, and extremely comfortable to wear. They come with more convenient ways to correct eye vision problems than the conventional eyeglasses.

These contact lenses are further classified as soft contact lenses and rigid gas-permeable contact lenses. this classification is done on the basis of manufacturing material used to make the lens. Soft contact lenses are made of very fine polymer and are gel-like, thin lenses while rigid gas-permeable lenses are made of glass. rigid gas-permeable lenses are hard and allow more oxygen to permeate through the lens.
