Will I be blind or visually impaired from my eye cancer?

Most people who have an eye cancer do not become blind or significantly visually impaired. Our visual function usually is described in terms of visual acuity and visual fields in both eyes.Visual acuity is expressed as a fraction; the top number refers to the distance you are from the eye chart (usually 20 feet). The bottom number indicates the distance at which a person with normal eyesight could read the line.Visual fields refers to the full extent of the area visible to an eye that is looking straight ahead. A normal visual field is 170 degrees.
