Understanding Corneal Ulcer
Corneal ulcers are most often caused by bacteria, and less often by viruses (such as herpes), fungi, or parasites. Sleeping in contact lenses is the single biggest risk factor. Eye injuries, severe dry eye, and eyelid problems that prevent the eye from closing also raise the risk.
Common symptoms
- Eye pain and redness
- A feeling that something is in the eye
- Light sensitivity
- Blurry vision and tearing or discharge
- A white spot on the cornea
When to seek care right away
A painful red eye with light sensitivity — especially if you wear contact lenses — should be seen the same day. Remove your lenses and call us.

Frequently asked questions
Can I keep wearing contacts with a red, painful eye?
No. Remove your lenses right away, don't put them back in, and get examined. Bring the lenses and case with you.
