Abstract:
The invention provides a method for designing tinted contact lenses that permits the computer-assisted modeling of a tinted lens on-eye. The method of the invention provides a substantially accurate prediction as to the appearance of the lens on-eye and reduces the number of designs that must be clinically tested and the number of iterations that each design must go through.
An ophthalmic lens incorporating clearly identifiable, highly visible embedded labels that are not visible to the wearer or others when placed on the eye may be utilized to allow an individual to easily distinguish between the normal state of the lens and the inverted state of the lens as well as serve any number of functions, including acting as a brand label, a prescription label or as a cosmetic enhancer. The embedded label comprises holographic recordings revealed only in transmitted light.
