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.

Abstract: A photochromic ophthalmic lens may comprise a main body comprising an optical zone and a peripheral zone disposed adjacent the optical zone, wherein one or more of the optical zone and the peripheral zone comprises a photochromic dye, wherein the ophthalmic lens has a thickness profile that is configured based on cosmetic appearance associated with a target level of transmission (% T), and wherein at least a portion of the thickness profile is the same across two or more stock keeping units (SKU), each of the two or more SKU having a different target prescription.

Abstract: The disclosure is related to a new soft contact lens with edge to edge photochromic material where geometry of the optical region and the peripheral region of the lens are optimized to give the best cosmetic effect on eye. The vision correction component and the mechanical component of that soft contact lens are designed independently from each other. The design of each component, vision and mechanical, is achieved by the mean of using diffractive optics.
