People sometimes call it “eyeball sunburn,” but the medical term is usually photokeratitis: UV injury to the clear front surface of the eye (the cornea) and sometimes the surrounding conjunctiva. It can happen after strong sun, reflected UV from snow or water, tanning beds, welding arcs, or certain UV lamps.
Eye pain, light sensitivity, tearing, a gritty feeling, redness, or blurred vision after UV exposure should be assessed promptly by an eye-care professional or urgent-care service. Do not try to treat a suspected eye sunburn with numbing drops, leftover antibiotic drops, or an eye patch at home.
Key Takeaways
- “Sunburn in the eyes” usually means photokeratitis, a UV injury to the cornea.
- Symptoms often start hours after exposure, not necessarily while you are outside.
- Common signs include pain, a gritty or sandy sensation, tearing, red eyes, light sensitivity, and blurred vision.
- Remove contact lenses, get out of UV exposure, avoid rubbing your eyes, and seek prompt professional advice.
- Sudden vision loss, severe pain, a chemical exposure, or a foreign body in the eye needs emergency assessment.
- Proper UV-blocking sunglasses and close-fitting protective eyewear are the main prevention tools.
Can your eyeballs get sunburned?
Not in the same way skin does, but UV can injure the surface of the eye. The cornea absorbs UV, and a strong dose can damage its surface cells. That injury is called photokeratitis or ultraviolet keratitis. It is sometimes known as snow blindness when reflected UV from snow is the trigger.
Photokeratitis has a well-supported causal association with solar UV exposure in humans. [Dolin and Johnson, Ophthalmic Epidemiology, 1994]
Sunburned-eye symptoms
Symptoms are often delayed. You may feel fine outdoors, then develop discomfort several hours later. Both eyes are commonly affected after environmental UV exposure, but one-sided symptoms can point to a different problem, such as a foreign body or contact-lens issue.
- Eye pain or burning
- A gritty, sandy, or foreign-body sensation
- Tearing or watery eyes
- Redness and swollen eyelids
- Light sensitivity (photophobia)
- Blurred or reduced vision
- Headache from keeping the eyes closed or avoiding light
A recent photokeratitis case series documented delayed eye pain, redness, tearing, and light sensitivity after recreational UV exposure. [Chan et al., JAMA Ophthalmology, 2024]
What to do if you think you have sunburn in your eyes
Stop UV exposure and reduce light
Go indoors or into shade. Use sunglasses outdoors and dim indoor lighting if bright light worsens symptoms. Do not keep testing your eyes by looking toward the sun or bright lamps.
Remove contact lenses
Take out contact lenses and do not wear them again until an eye professional says it is safe or symptoms have fully resolved. Contact lenses can worsen irritation and make it harder to judge what is happening on the eye surface.
Do not rub, patch, or medicate the eye yourself
Rubbing can worsen a corneal injury. Avoid anesthetic or “numbing” eye drops, leftover antibiotics, steroid drops, redness-relief drops, and homemade rinses unless prescribed for this episode. Do not patch the eye. An eye professional may recommend lubricating drops or other treatment after examining you, but the right choice depends on the diagnosis.
Arrange prompt assessment
Call an optometrist, ophthalmologist, urgent-care service, or local medical advice line, especially if you have pain, light sensitivity, or vision change. They can check visual acuity and use fluorescein staining to look for corneal surface injury or another cause.
When to seek emergency care
Get emergency help now for sudden or marked vision loss, severe pain, a chemical splash, an object in the eye, a penetrating injury, severe headache with nausea and eye pain, or symptoms that are rapidly worsening. Eye symptoms can overlap with infections, acute glaucoma, corneal abrasion, uveitis, and other conditions that should not be self-diagnosed as sunburn.
How long does photokeratitis last?
Many uncomplicated cases improve within one to three days once UV exposure stops, but you should not use that timeframe to delay an eye assessment if vision is affected or pain is significant. Recovery depends on the severity and whether another eye condition is present.
If symptoms do not improve, worsen, or return when you resume contact lenses, get re-evaluated.
Common causes of eye sunburn
- Strong direct sun, especially at high altitude
- Reflection from snow, water, sand, or ice
- Not wearing UV-blocking sunglasses
- Tanning beds or UV lamps
- Welding or industrial UV sources without appropriate eye protection
What can feel similar to an eye sunburn?
Photokeratitis is only one reason an eye can be painful, red, watery, or sensitive to light. Contact-lens overwear, dry eye, a trapped eyelash or foreign body, viral conjunctivitis, allergy, chemical irritation, and a corneal abrasion can overlap with these symptoms. That is why a history of UV exposure is useful, but it does not confirm the diagnosis.
Do not assume a red eye is harmless because both eyes are involved, and do not share towels, makeup, or contact-lens cases if an infection has not been ruled out. Eye professionals can distinguish these conditions with an examination.
Clouds do not reliably block enough UV to protect eyes. Our guide to tanning when it is cloudy explains why. Checking the UV index can also help you plan eye protection on high-exposure days.
How to prevent sunburn in the eyes
Choose sunglasses labeled to block UVA and UVB or provide 100% UV protection. Larger frames or wraparound styles reduce light entering around the sides. Add a wide-brimmed hat and seek shade, especially around reflective surfaces or at high altitude.
Regular sunscreen protects the skin around your eyes but does not protect the eyeball itself. Apply it carefully so it does not run into the eyes. For skin protection, see can you tan with sunscreen? and our guide to sunblock options to prevent tanning.
How to choose protective sunglasses
Prioritize the UV-protection label over lens darkness or price. Dark lenses without reliable UV filtering can make pupils open wider while still allowing UV exposure. A comfortable pair that stays on your face, covers the eye area, and is used consistently is better than a fashionable pair left in a bag.
Frequently Asked Questions
Can you get eye sunburn through sunglasses?
Yes, if the lenses do not provide genuine UV protection or if significant UV enters around the sides. Choose properly labeled UV-blocking eyewear and a frame that covers the eye area well.
Can I use artificial tears for sunburned eyes?
Lubricating drops may be appropriate for some eye irritation, but persistent pain, light sensitivity, or blurred vision after UV exposure needs professional assessment. Do not use anesthetic, steroid, antibiotic, or redness-relief drops unless prescribed for the current problem.
Is photokeratitis contagious?
No. Photokeratitis is a UV injury, not an infection. However, red, painful eyes can also be caused by contagious conjunctivitis or other conditions, so do not assume the cause without an assessment.
Can tanning beds cause eye sunburn?
Yes. UV from tanning beds can injure eyes if appropriate protective goggles are not worn. Closing your eyes is not a substitute for purpose-designed protection.
Final Thoughts
Eye sunburn is a real UV injury, not just a little eye strain. Treat pain, light sensitivity, tearing, or visual changes after strong UV exposure as a reason for prompt eye-care advice. UV-blocking sunglasses, a hat, and shade are simple habits that help prevent it.
