Toric contact lens with meniscus-shaped top and bottom flattened zones for dynamic stabilization

摘要

A toric contact lens incorporating meniscus-shaped top and bottom flattened zones for dynamic stabilization comprises a convex outer surface and a concave inner surface. The lens has a central optic zone, a top meniscus-shaped flattened zone formed between upper edge of the optic zone and upper edge of the convex outer surface, and a bottom meniscus-shaped flattened zone between lower edge of the optic zone and lower edge of the convex outer surface, where a left intersection and a right intersection are formed by said top flattened zone intersecting said bottom flattened zone on both sides, which in turn form a plurality of horizontal positional lines each.
