Abstract: A high energy visible (HEV) light absorbing material and application method for an ophthalmic substrate includes deposition of an HEV light absorbing material onto the ophthalmic substrate. The HEV light absorbing material is applied through physical vapor deposition as a thin layer on ophthalmic substrates for flexibility and color adaptation. The HEV light absorbing material includes at least one of: aluminum zinc oxide, indium zinc oxide and gallium zinc oxide with a material commonly used in the design of antireflective absorbing materials. The HEV light absorbing coating is antireflective and transmits up to 98% of light for the rest of spectrum. The HEV light absorbing material allows the ophthalmic substrate to selectively absorb blue light that falls in the wavelength range of about 400 nm to about 460 nm.

Abstract: A high energy visible (HEV) light absorbing material for an ophthalmic substrate and application through physical vapor deposition. The HEV light absorbing material is deposited onto the ophthalmic substrate, such as an optical lens. The HEV light absorbing material is applied through physical vapor deposition. The HEV light absorbing material is applied as a thin layer on ophthalmic substrates for flexibility and color adaptation. The HEV light absorbing material includes at least one of: aluminum zinc oxide, indium zinc oxide and gallium zinc oxide with a material commonly used in the design of antireflective absorbing materials. The HEV light absorbing coating is antireflective and transmits up to 98% of light for the rest of spectrum. The HEV light absorbing material allows the ophthalmic substrate to selectively absorb blue light that falls in the wavelength range of about 400 nm to about 460 nm so that flux of blue light to the internal structures of the eye is reduced.
