Many people with Lazy Eye (amblyopia), especially those who are only mildly so, are not even aware they have the condition until tested at older ages, since the vision in their stronger eye is normal.
However, people who have ''severe'' amblyopia may experience associated visual disorders, most notably poor depth perception.
Amblyopes may suffer from poor spatial acuity, low sensitivity to contrast and some "higher-level" deficits to vision such as reduced sensitivity to motion.
These deficits are usually specific to the amblyopic eye.
Amblyopes also suffer from problems of binocular vision such as limited stereoscopic depth perception and usually have difficulty seeing the three-dimensional images in hidden stereoscopic displays such as autostereograms.
However perception of depth from monocular cues such as size, perspective, and motion parallax is normal.
