The lens of the human eye comprises a highly concentrated protein solution, which lends the lens its great refractive power. Protective proteins prevent these proteins from clumping together ...

FRANKFURT. The lens of the human eye gets its transparency and refractive power from the fact that certain proteins are densely packed in its cells. These are mainly crystallines. If this dense ...

A study on ground squirrels shows, not only do mitochondria produce bioenergy in the cone-shaped photoreceptors in the retina of the eye, they also act as micro-lenses that redirect light to the ...

Sleeping in contact lenses can reduce oxygen to the cornea and weaken eye health. Contacts worn overnight can trap bacteria ...

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, ...
