Light Sensitivity
While mild light sensitivity can be a pointer to several eye conditions such as keratoconus, corneal abrasion, strabismus, and cataracts, it is a sure sign that something is definitely wrong with one’s eyes. [4] It could manifest as squinting in a brightly-lit room or outside in the sunshine. At any rate, if you can’t seem to bear exposure to mild light (or more seriously you have a headache when you try to), it is a serious cause for concern. You should see a doctor.
