Cataract
Make it clearer
A cataract is an area inside the eye's lens that has lost its transparency. Picture looking through a window with one cloudy patch: whatever lies beyond that patch no longer looks as clear.
That is why a cataract can make vision blurry or hazy and can make colors look less vivid. These changes can occur, but they do not appear in exactly the same way with every cataract.
In brief
A cataract is a cloudy area in the lens of the eye. This definition describes a change in the lens itself; it does not, by itself, establish the cause or severity.
Clouding of the lens can make vision seem blurry, hazy, or less colorful. These are possible effects of a cataract, not a universal diagnostic checklist.
