Ophthalmic lens with reduced edge glare and method of making |
摘要 |
An opthalmic lens and a method of making is disclosed. The lens has a one-piece lens body with an integral edge surface. The edge surface reflects visible light which contacts the edge surface away from the retina of the patient. The edge surface has beveled portions or a curve of a convex form. The bevels or convex form are displayed on the edge by milling with a milling cutter having a shape matching that desired on the edge. This lens design reduces glare seen by the patient caused when incident light contacts the edge surface and is undesirably reflected onto the retina.
