Which vitamin is good for eyesight?

Taking extra vitamins does not establish a treatment for every cause of poor eyesight.

The NIH vitamin A fact sheet describes how deficiency can impair low-light vision. Supplement choice should depend on your diet, diagnosis and professional advice.

The National Eye Institute healthy-vision advice recommends a balanced diet with varied fruit and vegetables, including leafy greens. Seek an eye-care professional’s advice for changes in vision.
