One of the most complained-about problems in all of eye care is light sensitivity. It comes up all the time. Almost every keratitis case has light sensitivity (or "photophobia"). Anterior uveitis, conjunctivitis, acute glaucoma, certain types of cataracts...many, many eye problems can cause your eyes to be sensitive to light. If you have acute light sensitivity in ONE EYE only, you need to go to the optometrist or ophthalmologist right away. But let's talk about those cases when the patient tells us "lights hurt my eyes", and they're just talking about generally being bothered by lights in both eyes in the absence of some acute medical problem like keratitis or uveitis. Fluorescent lighting or glare from bright sunshine and the like. There are things we can do to help you: apply tints to your glasses in the case of bright sunshine, anti-reflection and blue-blocking coatings in the case of in-office fluorescent office lighting. Ask your optometrist about these solutions!
