Chemical bonds within the eye-lens protein gamma-B crystallin hold the protein together and are therefore important for the function of the protein within the lens. Contrary to previous assumptions, ...

α-Crystallin is a major lens protein, comprising up to 40% of total lens proteins, where its structural function is to assist in maintaining the proper refractive index in the lens. In addition to its ...

The bifocal lenses are made from bilayer structures of liquid crystal (LC) cells and LC polymer. These lenses split light with a left-handed circular polarization (LCP) into two focused light beams ...

Monofocal and multifocal lenses are both types of artificial intraocular lens (IOL). A monofocal lens has one focusing distance, whereas a multifocal lens can focus on close and far distances at the ...

Scleral lenses are large contact lenses that rest on the sclera, the white part of the eye, rather than the cornea. The lenses contain saline, so the cornea stays moist, which is helpful for people ...
