Here is a full breakdown of what happens when sanitizer gets in your eyes:

What Happens When Sanitizer Gets in Your Eyes

Hand sanitizers contain 60-80% alcohol (ethanol or isopropanol). The moment it contacts your eye, it starts causing damage through two main mechanisms:

Immediate Effects

  • Burning and stinging - intense, almost instant pain
  • Reflex tearing - the eye floods with tears trying to flush the irritant out
  • Redness (conjunctival injection) - blood vessels in the white of the eye dilate
  • Photophobia - sensitivity to light
  • Blurred vision - temporary, from the disruption of the tear film and corneal surface

What the Alcohol Does to Eye Tissue

The high-concentration alcohol strips away the protective tear film that coats your cornea and conjunctiva. It then disrupts the delicate cell membranes on the corneal surface. In mild exposures (a small splash, quickly rinsed), this heals within 24-48 hours. In more prolonged or heavy exposures, the corneal epithelium (outer layer) can be damaged more significantly, causing a chemical keratitis (corneal inflammation).
According to the FDA's safety communication, sanitizer in the eyes can cause serious injury, and this type of injury increased significantly during the COVID-19 pandemic as sanitizer use rose.

Severity Factors

The degree of injury depends on:
  • How much sanitizer entered the eye
  • How long it stayed before rinsing began
  • Concentration of alcohol in the product
  • Whether contact lenses were being worn (lenses can trap the chemical against the eye)

First Aid - What to Do Immediately

  1. Rinse immediately - flush the eye with clean, lukewarm water for at least 15-20 minutes. More is better. Hold the eye open and let water flow from the inner corner outward.
  2. Remove contacts - if you wear contact lenses, remove them before or during rinsing if possible.
  3. Do not rub - rubbing spreads the chemical and can scratch the cornea.
  4. Call Poison Control - in the US: 1-800-222-1222. They can assess the severity over the phone.
  5. See a doctor - go to an eye doctor or emergency room, especially if symptoms persist after rinsing (ongoing pain, blurry vision, light sensitivity, or visible redness).

When to Seek Emergency Care

Go to an emergency room or eye specialist if:
  • Pain or burning continues after 20+ minutes of rinsing
  • Vision remains blurry after rinsing
  • The eye looks visibly red or swollen
  • A child was exposed (children are at higher risk and less able to cooperate with rinsing)
  • A large amount of sanitizer entered the eye
As Mayo Clinic notes, any significant chemical splash in the eye warrants emergency evaluation by an ophthalmologist.

Prognosis

Most cases from incidental splashes resolve completely with prompt irrigation. Serious permanent eye damage is rare but possible with prolonged, unrinsed exposure. The key factor is how fast you rinse - every second counts in reducing the extent of injury.
Do not use eyedrops, milk, or other substances to rinse. Plain water or saline is ideal. If saline eye wash is available (common in first aid kits), use it.
