Contact lenses are designed to address virtually any vision need — nearsightedness, farsightedness, aging eyes (presbyopia), and eyes with irregular shapes (astigmatism). In addition, there are contact lenses that enhance or change eye color. Finally, there are specialty contact lenses designed to maximize sports performance or address conditions like dry eyes and glare.

The news gets even better. These many types of contact lens designs now are available in disposable or planned replacement multipacks. This makes it economical to try contact lenses — or even to be an occasional contact lens wearer. Many eyeglass wearers are thrilled to put on a pair of disposable contact lenses to play tennis or to go out for an evening of dancing.
