4. Light sensitivity.
Patients who are afflicted with keratitis often report that their eyes are more sensitive to light than usual; even exposure to low levels of light can be painful. The cornea, the part of the eye that is affected by keratitis, covers the iris and pupil; all three elements play an important part in vision, as they help to filter light, which allows your eye to focus so that you can see properly.
If the cornea is inflamed, however, the eye cannot effectively filter out the light; as such, more light may be entering your eye, which can lead to light sensitivity. If your levels of light that don’t usually irritate your eyes suddenly seem blinding – especially if any other symptoms mentioned here are present – keratitis could be to blame.
Do not dismiss this symptom; it is important that you have your eyes assessed to avoid serious problems.
