Eyes & Vision
Snow Blindness
A painful, temporary 'sunburn' of the eye's surface from intense UV light off snow, water, or sand — it heals on its own with rest in the dark.
Also known as: Photokeratitis, UV eye burn
📝 At a glance
Likely root causes: Intense UV light reflected off snow, water, ice, or sand; High-altitude sun without eye protection; Welding or sunlamps without proper eye protection.
First thing to try: Get out of the bright light and into a cool, dark room, and remove contact lenses.
See a doctor if: Pain or blurred vision that doesn't improve within a day or two
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Intense UV light reflected off snow, water, ice, or sand
- High-altitude sun without eye protection
- Welding or sunlamps without proper eye protection
- Not wearing UV-blocking sunglasses or goggles
Change what you can
- Get out of the bright light and into a cool, dark room, and remove contact lenses.
- Rest the eyes — keeping them closed — and use cool compresses over the lids for comfort.
- Use lubricating (artificial tear) drops; the surface heals on its own within a day or two.
- Don't rub the eyes, and prevent it next time with UV-blocking sunglasses or goggles.
- Avoid screens and bright light while the eyes are recovering.
- Take over-the-counter pain relief if the eyes feel achy or sore.
- Wear wraparound sunglasses even indoors near bright windows until symptoms ease.
- See a doctor if pain, light sensitivity, or blurry vision lasts more than two days, or vision doesn't return to normal.

★ Start here — our first-line pick, pinned for safety
Dark rest with closed eyes is the safest first step — nothing should be applied to the eyes themselves.
How to do it ▾
Why it works: Snow blindness is a surface burn from UV light, much like a sunburn on the skin, and the cornea heals itself within a day or two when shielded from further light and rubbing.
- Get out of the bright light and into a cool, dark room right away.
- Remove contact lenses if worn.
- Close the eyes and rest them, avoiding screens and bright light.
- Apply a cool, clean compress over the closed lids for comfort.
Rest for several hours, repeat compresses as needed · Continuous rest the first day, compresses every hour or two as needed
Caution: Never rub the eyes, as this worsens the surface injury. Do not apply anything other than a cool compress to the closed lids — nothing should go into or directly onto the eye itself.
When to get help: See an eye doctor promptly if pain or vision changes don't improve within a day or two, or right away for any chemical splash or impact injury.

The best way to prevent snow blindness from recurring.
How to do it ▾
Why it works: Sunglasses or goggles that block 99-100% of UV rays prevent the reflected ultraviolet light from ever reaching and burning the eye's surface.
- Choose sunglasses or goggles labeled to block 99-100% of UV rays.
- Wear them anytime you'll be around snow, water, sand, or at high altitude in bright sun.
- Keep a spare pair on hand for group outings so no one goes without.
- Replace scratched or damaged eyewear that no longer fits snugly.
Ongoing use during sun exposure · Every time in bright reflective conditions
Caution: Regular sunglasses that don't block UV can give a false sense of protection. Do not skip eye protection at high altitude even on cloudy days, since UV exposure is still strong.
When to get help: See an eye doctor promptly for any eye pain or vision change that doesn't resolve within a day or two despite prevention.

A gentle comfort measure to use alongside dark rest, using only plain lubricating drops.
How to do it ▾
Why it works: Lubricating drops replace natural moisture the irritated eye surface may lack, easing dryness and grittiness while the corneal surface cells regenerate.
- Wash hands before applying any drops.
- Use only plain lubricating (artificial tear) drops made for the eyes.
- Apply as directed on the product, typically a drop in each eye as needed for comfort.
- Continue rest in a dark room between applications.
A few seconds per application · As needed for comfort, several times a day
Caution: Use only plain saline-based artificial tears — never any other liquid, remedy, or substance in the eyes. Stop and seek care if drops cause increased pain or irritation.
When to get help: See an eye doctor promptly for pain, discharge, or a foreign-body sensation that persists beyond a day or two.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health...

🌿 Overview
Snow blindness (photokeratitis) is essentially sunburn of the cornea, caused by intense ultraviolet light reflected off snow, water, sand, or from welding without eye protection. It's painful but temporary, and the eye's surface heals on its own within a day or two.
Strong UV light burns the delicate surface of the eye, and a few hours later the eyes become painful, gritty, watery, and very sensitive to light, sometimes with blurred vision. It's common in skiers, mountaineers, and at the beach without good sunglasses.
The care is simple: get out of the bright light, remove contact lenses, rest the eyes in a dark room, and use cool compresses and lubricating drops for comfort. It heals within a day or two. UV-blocking sunglasses or goggles prevent it. Any pain or vision change that doesn't settle, or any chemical or impact injury, needs an eye doctor.
Common signs
- Painful, gritty, watery eyes a few hours after strong UV exposure
- Strong sensitivity to light and blurred vision
- Redness and a feeling of sand in the eyes
- Sometimes temporary loss of vision (it returns)
