The two eyes see different colors, that is, there is chromatic aberration, mainly due to the following reasons: First, due to clouding of the lens, also known as cataract caused by the cataract occurs when the severity of the two eyes are usually inconsistent, the degree of heavier eye lens density is higher, the color will be brownish yellow, resulting in this eye looks warm tones, yellowish color. Second, due to central plasmacytochoroidal retinopathy, which usually develops in one eye and results in seeing a darker scene, like a faded photograph, and also results in seeing things differently in both eyes. Third, due to a small amount of vitreous blood accumulation, when a small amount of hemorrhage enters the vitreous cavity it will diffuse in the vitreous cavity, making the color of the vitreous turn pink, thus causing the eye with hemorrhage to see a reddish scene, causing both eyes to see things in different colors.
