An eyepiece, or ocular lens, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes.

The eyepiece, or ocular lens, is a cylinder containing two or more lenses; its function is to bring the image into focus for the eye.

With only one ocular lens you can't project a true picture... unless we also have a 3rd lens.

Binoculars have a focusing arrangement which changes the distance between ocular and objective lenses.

The MIP protein is expressed in the ocular lens and is required for correct lens function.

Their faces were obscured by visored helmets - ocular lenses where the features should have been -which gave them a blank, robotic look.

Sphingomyelin content in mammals ranges from 2 to 15% in most tissues, with higher concentrations found in nerve tissues, red blood cells, and the ocular lenses.

SOX2 has been implicated in a substantial number (10-15%) of cases and in many other cases failure to develop the ocular lens often results in microphthamia.

I peered through the ocular lens.

Sunglasses are especially important for children, as their ocular lenses are thought to transmit far more HEV light than adults (lenses "yellow" with age).
