Light-sensitive photochromic contact lens demonstration devices and related methods

Abstract

Light-sensitive photochromic contact lens demonstration devices and related methods are disclosed. To provide for the convenient and efficient demonstration of a photochromic contact lens change, the demonstration device includes a controllable lighting-emitting device to expose a demonstrated photochromic contact lens to UltraViolet (UV) and/or High-Energy Visible (HEV) light to cause a photochromic contact lens to change from a non-darkened to darkened state. The demonstration device also includes a viewing window that allows viewing of the contact lens changing from a non-darkened to darkened state as a result of exposure to UV/HEV light and back to a non-darkened state when the light is removed. Further, the photochromic contact lens demonstration device can also include an optional heating circuit to heat the photochromic contact lens during demonstration to cause the photochromic contact lens to change from a darkened state back to a non-darkened state more quickly.
