The prism de-focuses the light focused by lenses in the focal point of the lens away from the optical eye. The light falls more on structures lying in the direct vicinity of the focal point. The body has one or more arms fixed to it and enables the body to be best centered in the ...
Listen to part of a lecture in a biology class. Professor: I think the lens of the eyes just about the most fascinating part of the body. For one, it's the only, I repeat only transparent cellular tissue in the human body. In fact, truly transparent tissue is very uncommon in nature...

Contact lens, thin artificial lens worn on the surface of the eye to correct refractive defects of vision. The first contact lens, made of glass, was developed by Adolf Fick in 1887 to correct irregular astigmatism. The early lenses, however, were uncomf
the human eye is often discussed as optically equivalent to a photographic camera ([2][1]). The iris is compared with the shutter, the pupil to the aperture, and the retina to the film, and both have lens systems to focus rays of light. Although many similarities exist, a major differe...
The present invention is a lens designed for implantation into the capsule of a human eye. The element forming the optic component is provided with supporting loops, the ends of which have been inserted into the periphery of said element, through holes being provided in said periphery. The loop...
The present invention relates generally to the field of apparatus and methods for surgically implanting artificial lenses in the human eye, and particularly to the implanting of artificial intra-ocular lenses in cataract surgery in place of diseased or damaged natural intra-ocular lenses as part of ...
