ποΈ How Cataracts Make the Eye Lens Cloudy
A cataract is a cloudy area within the eyeβs lens. Changes in lens proteins can make them clump and interfere with light passing clearly toward the retina.

What the illustration shows
Educational poster titled βHow Cataracts Make the Eye Lens Cloudy,β with an eye icon. On a navy field, an oblique eye cutaway faces left. Labels identify the clear outer cornea, blue iris, lens behind the iris, a white cloudy area inside that lens, and the retina lining the back of the eye. Cyan and gold light arrows extend through and behind the lens and are explicitly marked schematic. A lower-left enlarged lens shows an internal cloudy patch. A lower-right inset shows separate ivory protein symbols beside an arrow leading to a cluster, labeled schematic, not a molecular model. Text explains that cataracts are cloudy areas within the lens, that changes in lens proteins can make them clump, and that cloudy areas interfere with light passing clearly toward the retina. Gold AllHumanBody.com and the full project slogan sit on a plain navy footer. Opacity placement, colors and protein shapes are illustrative, not a patient image or diagnostic test.
