Freebase

  1. Cataract

    A cataract is a clouding of the lens inside the eye which leads to a decrease in vision. It is the most common cause of blindness and is conventionally treated with surgery. Visual loss occurs because opacification of the lens obstructs light from passing and being focused on to the retina at the back of the eye. It is most commonly due to biological aging but there are a wide variety of other causes. Over time, yellow-brown pigment is deposited within the lens and this, together with disruption of the normal architecture of the lens fibers, leads to reduced transmission of light, which in turn leads to visual problems. Those with cataract commonly experience difficulty appreciating colors and changes in contrast, driving, reading, recognizing faces, and experience problems coping with glare from bright lights.

Chambers 20th Century Dictionary

  1. Cataract

    kat′a-rakt, n. a great fall of water, water-spout, &c.: a waterfall or cascade: an opaque condition of the lens of the eye, painless, unaccompanied by inflammation, occasioning blindness, simply by obstructing the passage of the light. [L. cataracta—Gr. kata, down, arass-ein, to dash, to rush.]
