Specialized contact lenses or intraocular lenses can help correct this issue.

Disease caused by loss of vitamin A?
Night blindness: In dim light, vision relies on the pigment rhodopsin (visual purple). Retinol is a crucial part of pigment rhodopsin. The loss/lack of retinol may result in "dark adaptation". Corneal Xeroses: Cornea becomes dry and hazy.
