The symptoms of photophobia are mainly encountering bright light, and some people may even experience light that produces significant blinding symptoms, causing soreness, stinging, or even inability to open the eyes. Photophobia may be caused by lesions at the corneal level, more commonly dry eye, which causes punctate clouding of the corneal epithelium, or damage to the corneal epithelium. It is necessary to go to the hospital for an examination where the doctor can determine the extent of corneal damage under the slit lamp, especially the depth and area of the damage, and can take the appropriate medication. For example, if the damage is only at the epithelial level, anti-inflammatory drugs and corneal nourishing drugs can be used and recovery can be made in 2-3 days. If the injury is at the stromal level, not only medication but also some bandaging may be required to promote recovery. If there is significant infectious inflammation, antiviral or antibacterial medications may also be required.
