Eyeglasses are disclosed that include eyeglass frames and a pair of ophthalmic lenses mounted in the frames. The lenses include a dot pattern distributed across each lens, the dot pattern including an array of dots spaced apart by a distance of 1 mm or less, each dot having a maximum dimension of 0.3 mm or less, the dot pattern including a clear aperture free of dots having a maximum dimension of more than 1 mm, the clear aperture being aligned with a viewing axis of a wearer of the pair of eyeglasses.

Provided are a lens for spectacles containing a resin and a coloring agent having a maximum absorption wavelength in a methanol solution in a range of 400 nm to 500 nm and a half-width of an absorption peak in a methanol solution of 10 nm or more and less than 40 nm, and spectacles.

Methods and apparatus are provided for eyeglass lens made using a solution casting process. The method may include providing a first soluble polymer solution. The method may include providing a first dye solution including at least one dye. The method may include adding the first dye solution to the first soluble polymer solution to form a first dyed solution. The method may include casting the first dyed solution to form a first film. The method may include providing a second soluble polymer solution. The method may include providing a second dye solution comprising at least one dye. The method may include adding the second dye solution to the second soluble polymer solution to form a second dyed solution. The method may include casting the second dyed solution onto the first film to form a two-layer film. The method may include laminating or casting the two-layer film to the eyeglass lens.

Contact lenses are provided with tints that enhance performance and are shaped to permit wearing by individuals who are unfamiliar with contact lens handlings. With suitable contact lens shapes, applying and removing the contact lenses is simple, and providing tints on a contact lens permits using more transmissive tints than would be needed for spectacles or goggles. In addition, using tinted contact lenses avoids some of the physical limitations and problems associated with spectacles and goggles.

An eyeglass frame configured to hold corrective lenses therein is removably engageable with a protective lens. The protective lens has connectors on opposing ends which are engageable with first and second mounts engaged to the frame. A gap is formed between the protective lens and the front surface of the frame and is maintained by the engagement of the connectors with the respective mounts.

The present invention relates to a novel lens unit being configured for spectral selective retinal stimulation modulation, which is advantageously a passive modulation effect in the lens of the invention. More specifically, the lens unit comprises a lens substrate having a certain volume defining a front and back surface, wherein the lens unit carries a spectral coder which, when the lens unit is in use, operates as a temporal spectral coder with respect to a portion of input light interacting with the lens unit and reaching the eye.
