Albino vision. Albinism has moderate and severe forms. Refractive needs are common. The eyes as a protective measure commonly develop a dancing motion (nystagmus) which lowers the central acuity. Light sensitivity is of course the rule. There are advances in this know to your ophthalmologist who you should consult when the condition is first detected.
Depends. Can be none to very profound. Nothing you can do except get it checked out and monitored- glasses can help if there is astigmatism or other high refractive disorder.
