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.
Claims20
An ophthalmic lens for wavelength selective filtering, fluorescence and/or scattering, comprising:
- a first layer of a substrate;
- a second layer of a substrate;
- and
- a film positioned between the first layer and the second layer, the film comprising a plurality of particles or dyes configured to scatter, filter, blur, generate, or absorb selected wavelengths of light.
A method of fabricating an ophthalmic lens for wavelength selective scattering, comprising the steps of:
- dispersing a plurality of particles or dyes in a medium;
- and
- applying the medium to an ophthalmic lens.
