cataract noun [ ˈkatərakt ]

• a medical condition in which the lens of the eye becomes progressively opaque, resulting in blurred vision.
• "she had cataracts in both eyes"
Similar: opacity, opaqueness,

Similar: waterfall, cascade, falls, rapids, white water, torrent, downpour, shower, force, linn,
Origin: late Middle English (in the sense ‘floodgate’): from Latin cataracta ‘waterfall, floodgate’, also ‘portcullis’ (medical cataract (sense 1) probably being a figurative use of this), from Greek kataraktēs ‘down-rushing’, from katarassein, from kata- ‘down’ + arassein ‘strike, smash’.
