Photophobia (light sensitivity) is typically diagnosed through a comprehensive eye exam. During the visit, an eye doctor will review your symptoms, medical history, and any triggers, then perform a close evaluation of your eyes to identify the underlying cause. Depending on findings, additional testing—such as neurological or imaging tests—may be recommended if the sensitivity is linked to migraines, infections, or other conditions.
Because photophobia can stem from many different causes—ranging from dry eye to more serious neurological issues—understanding your specific symptoms before your appointment can help you get answers faster. A free, instant, online symptom check can help you identify possible causes, prepare better questions for your doctor, and decide how urgently you should be seen. It takes just a few minutes and could save you time, stress, and unnecessary worry as you navigate your next steps.

The most common questions people search after this page
When you visit an eye doctor about photophobia (light sensitivity), they will begin by asking you questions about your symptoms and perform an exam. During this exam, they may look at your pupils—these are the dark parts in the middle of your eyes—to see how they react to light. They might also test how your eyes handle bright lights or glare. The doctor may also ask you about any headaches, eye pain, or other symptoms you have, because these might point to another condition causing your photophobia. Before your appointment, you can check your symptoms with Ubie's free AI-powered tool to help you better describe what you're experiencing to your doctor. The information you share, along with the tests, helps the doctor decide if something else, like an infection or migraine, might be causing your light sensitivity.
