A method for making a hydrogel, photochromic contact lens including supplying a first lens composition comprising a contact lens monomer and a photochromic material to a front contact lens mold and supplying a second lens composition to said contact lens mold wherein the viscosity of said first composition is at least about 1000 cp greater than the viscosity of said second contact lens composition, and the makeup of said second composition matches the of said first composition to reduce strain between said compositions of the resulting lens.

Pupil-only photochromic contact lenses displaying desirable optics and comfort

Disclosed in this specification is a process for manufacturing a thermochromic contact lens. The process includes (1) selecting a photoinitiator that absorbs at a first wavelength and at least one thermochromic dye that displays substantial absorption at the first wavelength when the dye is at a first temperature and exhibits at least an 80% reduction in absorbance at the first wavelength at a second temperature, (2) maintaining the reaction mixture at the second temperature and (3) providing cure light that includes the first wavelength.

Process for manufacture of a thermochromic contact lens material

The present invention relates to contact lenses which reduce indoor glare and provide improved comfort to the wearer. The contact lenses of the present invention have, at about body temperature, a percent transmission between 70 to 90% across the region of 420-700 nm.
