Optometrists encourage many patients to use daily disposable lenses, which are thrown away after each wearing. Automated manufacturing has lowered the cost of lenses enough to make this practice feasible. Most longer-lasting contact Lenses are made by clamping together plastic molds for the front and back surfaces of the lens. A thin layer of liquid polymer is squeezed into the remaining space and either cured with UV light or baked to turn it solid. Then, all the excess molecules are washed away and water is added.For its daily disposable lenses, CIBA Vision uses a material called nelfilcon A, a polyvinylalcohol. The material allows the manufacturing process to be fully automated. The lenses emerge with the water already incorporated. Because it takes only a few minutes to manufacture each lens, the process is efficient and a pair costs only about $1.

Lenses for nearsighted people are thin in the center but get thicker at the edge of that center zone. To correct farsightedness, lenses have a thick center that tapers down at the edge of the optical zone. Because standard Lenses are free to rotate as they sit on the eye''s surface, they can''t correct for astigmatism, a condition in which the cornea doesn''t have a spherical shape. Astigmatic eyes require toric lenses, which have different lens powers along different axes of vision. Recently, lens designers have produced contacts for astigmatism. By making the outer part of the lens, called the carrier portion, thicker on one side than the other, the manufacturer can lens ensure that the correction stays in line with the axis of irregular vision. As the wearer blinks and the lens moves, the thicker, heavier part stays at the bottom, ensuring that the lens is oriented correctly. These contacts have become widely available within the past 2 years.
