Abstract: An ophthalmic lens for selective scattering, filtering, or absorbing of selected wavelengths for treatment of various conditions. The ophthalmic lens may include dispersed particles or dyes configured to scatter, filter, or absorb such wavelengths. The dispersed particles may be formed into a laminate or film which is incorporated into the ophthalmic lens, such as by positioning between a pair of sheets of polycarbonate. The dispersed particles may be comprised of core-shell nanoparticles having varying properties, such as core and shell sizes, so as to control the wavelengths being scattered, filtered, or absorbed.

Abstract: A device may create an optical obstruction such as a haze for a predetermined amount of time in front of one or more eyes of the user and thereby trigger a blink response in the user. The device may include a lens having a plurality of layers and a sensor configured to detect a blink it at least one eye. At least one of the plurality of layers may include an electrodynamic layer in communication with the sensor. The electrodynamic layer may be configured to adjust the lens from a first state to a second state in response to a first signal from the sensor and from the second state back to the first state in response to a second signal from the sensor. The second state may include an at least partial obstruction of vision through the lens.

Abstract: A patterned lens with abrasion resistance having a base layer hard coat and a top hard coat. The base layer hardcoat may be formed on a film or sheet and used in molding the patterned lens. The top hard coat may be applied after molding.
