What do the Lens in the eye do?

Question

I am doing this for science and am unsure of what sites to look at (pardon the pun- Eyes/look at).

Answer 1

It focuses an image on the retina so that you can see it. The shape of the lens in the eye is controlled by muscles, so that the focal length can be adjusted to get sharp focus of both near and distant objects. Errors in the shape of the lens can be corrected with eyeglasses.

Answer 2

lens -- 1. The nearly spherical body in the eye, located behind the cornea, that focuses light rays onto the retina. 2. A device used to focus light into the eye in order to magnify or minify images, or otherwise correct visual problems. Eyeglass lenses, contact lenses, and intraocular lenses are examples. Sometimes a lens provides only a cosmetic benefit, as in non-correcting color contacts, special effect contacts, or contacts that hide a disfigurement of the eye. Other times a lens protects the eye, as in safety glasses or sunglasses. A bandage contact lens may be applied after eye surgery. And contact lenses used in ortho-k or corneal refractive therapy are designed to reshape the cornea for better vision when the lens is removed.

Answer 3

If you just quickly glance at a piece of paper with some letters on it from sort a couple feet away, it will appear as nothing. But similar to how a magnifying glass functions, the lens of your eyes refracts the light to help magnify the image.
