Contact Lenses

Trial and error often is involved in finding the perfect lens for you. People react differently to various lens materials and cleaning solutions. Also, the correct "parameters" of your lens — that is, power, diameter, and curvature — can be finalized only after you've successfully worn the lens. This is especially true for more complex fits involving extra parameters, such as with bifocals or toric contact lenses for astigmatism.
