In mild VI the person can easily read relatively larger characters and has no difficulty in identifying shapes, colors and brightness contrasts.

Symptoms of visual impairment include: lack of eye contact, no blinking of eyes, do not visually follow the moving objects in front of the eyes and no imitation of others expressions and actions, jerky movement of the eyeballs, limited facial expression and body language, search for the way using hands and abnormal response to white light.
