Abstract
The present invention relates to ophthalmic systems and coatings comprising a selective light wavelength filter, wherein said selective filter provides improved contrast sensitivity.
Claims70
An ophthalmic system comprising:
- an ophthalmic lens selected from the group consisting of a spectacle lens, contact lens, intra-ocular lens, corneal inlay, corneal onlay, corneal graft, and corneal tissue, and
- a selective light wavelength filter that blocks 5-50% of light in the range of 400-460 nm and transmits at least 80% of light in the range of 460-700 nm.
A coating for an ophthalmic lens that blocks 5-50% of light in the range of 400-460 nm and transmits at least 80% of light in the range of 460-700 nm.
The coating according to claim 30, whereby the coating is a hard coat.
An ophthalmic system comprising:
- an ophthalmic lens selected from the group consisting of a spectacle lens, contact lens, intra-ocular lens, corneal inlay, corneal onlay, corneal graft, and corneal tissue, said ophthalmic lens including a blue-absorbing dye that blocks 5-50% of light in the range of 400-460 nm and transmits at least 80% of light in the range of 460-700 nm;
- and
- a color-balancing coating on said ophthalmic lens.
An ophthalmic system comprising:
- a transparent material;
- and
- a coating on said transparent material, said coating a selective light wavelength filter that blocks 5-50% of light in the range of 400-460 nm and transmits at least 80% of light in the range of 460-700 nm.
