Abstract

A thin ophthalmic lens stabilized through incorporation of flange around all or a portion of a perimeter of the thin lens.

Claims (9)

1. A method for stabilizing an ophthalmic thin eyeglass lens comprising:

stretching a sheet of polarizing film onto a base lens substrate;

placing the sheet of polarizing film and the substrate in a mold to form a round, unfinished, thin eyeglass lens with a functional film molded thereto, the thin eyeglass lens having a cylindrical edge and a flange defining a perimeter extending radially outward from the cylindrical edge, the flange having a uniform thickness that is greater than a thickness of the cylindrical edge of the thin eyeglass lens;

removing the thin eyeglass lens from the mold; and

edging the thin eyeglass lens so as to remove the flange and shape the thin eyeglass lens to fit a desired eyeglass lens frame.

2. The method of claim 1 wherein obtaining the thin eyeglass lens having the cylindrical edge defining the thickness of the perimeter and the flange extending radially outward from the cylindrical edge comprises obtaining a thin eyeglass lens formed by injection molding.

3. The method of claim 1 wherein obtaining the thin eyeglass lens having the cylindrical edge defining the thickness of the perimeter and the flange extending radially outward from the cylindrical edge comprises obtaining a thin eyeglass lens having a thickness of the cylindrical edge that is in a range of 0.8 to 2.5 millimeters.

4. The method of claim 1 wherein obtaining the thin eyeglass lens having the cylindrical edge defining the thickness of the perimeter and the flange extending radially outward from the cylindrical edge comprises obtaining a thin eyeglass lens comprising a functional laminate.

5. The method of claim 1 wherein obtaining the thin eyeglass lens having the cylindrical edge defining the thickness of the perimeter and the flange extending radially outward from the cylindrical edge comprises obtaining a thin eyeglass lens having a flange having a width of 5 to 15 millimeters.
