optometrists discounts 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 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.
