What condition involves the fading or yellowing of colors and blurred vision at night?

Cataracts are a condition characterized by the clouding of the lens of the eye, which can lead to various visual disturbances, including fading or yellowing of colors and blurred vision, particularly in low-light conditions such as at night. The cloudiness affects how light enters the eye and is processed, causing a scatter of light and resulting in difficulty seeing, especially in darkness. People with cataracts may also experience halos around lights, increased sensitivity to glare, and impaired color perception, all of which make it challenging to see clearly.

Age-related macular degeneration primarily affects central vision and can lead to blind spots, but it does not typically cause color distortion or night vision problems in the same way cataracts do. Astigmatism involves distorted vision due to an irregular shape of the cornea but does not specifically cause the symptoms described. Retinal detachment can lead to sudden vision changes, including the perception of flashes or floaters, but it does not present with the gradual fading or yellowing of colors and blurred night vision associated with cataracts. Therefore, cataracts are the most fitting condition for the symptoms outlined.
