My eyes are very sensitive to light. Recently, an eye doctor told me my pupils are larger than normal. He pondered giving me drops to make my pupils smaller, then decided against it. He told me to buy nonprescription sunglasses. I asked if he recommended a certain type, but he said that it doesn't matter. However, sunglasses make me feel dizzy and nauseated. Do you have any suggestions? There are so many types of sunglasses to choose from.

A.R.

The medical term for sensitivity to light is called photophobia. Photophobia requires a thorough evaluation by an ophthalmologist because it can be a symptom of some very serious eye conditions, including infections, corneal abrasions and inflammatory diseases. All of these conditions are treatable, but failure to diagnose and treat them can lead to permanent loss of vision.

For people with photophobia that is not related to a serious eye problem, sunglasses with ultraviolet (UV) protection can be helpful. Anti-reflective coatings can also help reduce glare and decrease photosensitivity symptoms. A good optical shop can add both ultraviolet and anti-reflective coatings to almost any type of eyeglass lens.

I do not have a good answer as to why you feel dizzy and disoriented when wearing sunglasses. A good pair of sunglasses that is made correctly for you and fits your face/eyes correctly should not cause dizziness or other symptoms.
