In a -5.00 Rx made with 1.67 aspheric material, how do I achieve the flattest plate height?
In a -5.00 Rx made with 1.67 aspheric material, how do I achieve the flattest plate height?
By using a flat base curve, preferably with an aspheric or optimized free-form design. Anything else you do to reduce the edge thickness will also reduce the plate height.
