Takeaway
Photophobia refers to an extreme sensitivity to light that can be caused by a wide variety of issues. Its causes range from neurological and ocular conditions to eye injuries and prescription medications. Photophobia will typically resolve along with the underlying condition, according to Starr. For example, artificial tears may relieve photophobia triggered by dry eye, and photophobia associated with an eye injury will likely improve as the scratch, scrape, or cut heals.
In some cases, photophobia may suggest a more serious underlying condition, like glaucoma. So, if you regularly experience this symptom, you'll want to make an appointment with an eye doctor or other healthcare professional as soon as possible.
