Why Does Sunscreen Irritate Your Eyes? Here’s What You Need to Know

Sunscreen is a must-have for protecting your skin from harmful UV rays—but anyone who’s ever gotten sunscreen in their eyes knows it can be intensely uncomfortable. If you’ve felt the sting, watering, or burning sensation that can come from sunscreen near or in your eyes, you’re not alone. So, what causes this irritation, and how can you avoid it?

What Causes the Stinging Sensation?

The primary reason sunscreen can irritate your eyes comes down to its active ingredients. Most sunscreens fall into two categories: chemical and physical (mineral) sunscreens. Each works differently and has its own pros and cons when it comes to eye sensitivity.

1. Chemical Sunscreens and Eye Irritation

Chemical sunscreens use ingredients like:

• Oxybenzone

• Avobenzone

• Octinoxate

• Homosalate

• Octocrylene

These compounds absorb UV rays and convert them into heat, preventing skin damage. However, many of these ingredients can be irritating to the mucous membranes in and around the eyes.

Even if you don’t apply sunscreen directly near your eyes, sweat or water (from swimming or humidity) can carry the sunscreen into your eyes, causing stinging, redness, tearing, and discomfort.

2. Physical (Mineral) Sunscreens: A Gentler Option

Mineral sunscreens, which use:

• Zinc oxide

• Titanium dioxide

sit on top of the skin and reflect UV rays. These ingredients are less likely to cause eye irritation, making them a better choice for people with sensitive eyes or skin.

That said, even mineral sunscreens can cause discomfort if a large amount gets directly into the eye, simply because it’s a foreign substance.

Why Are Eyes So Sensitive?

Your eyes are protected by a delicate mucous membrane called the conjunctiva, which is highly sensitive to foreign substances—especially chemicals. Sunscreen, especially when combined with sweat or water, can easily migrate and come into contact with this membrane, triggering the body's response to flush out the irritant—hence the watering, stinging, and redness.

Tips to Prevent Sunscreen Eye Irritation

1. Choose the right formulaOpt for mineral sunscreens or ones specifically labeled “non-irritating” or “for sensitive skin.” Some products are even marked “eye-safe.”

2. Use a stick sunscreenStick formulations tend to stay put better than lotions or sprays, reducing the risk of migration into the eyes.

3. Apply carefully and avoid the eye contourApply sunscreen up to—but not on—the orbital bone (the area surrounding your eye socket). You can use sunglasses or a hat for extra protection around the eyes.

4. Let it absorbGive your sunscreen 10–15 minutes to absorb before heading out or sweating, which can help keep it from running.

5. Reapply with careWhen reapplying, especially during outdoor activities, be mindful of your forehead and brow area. Sweat can carry sunscreen downward.

What To Do If It Gets in Your Eyes

If sunscreen does get in your eyes:

• Rinse thoroughly with clean water or a saline solution.

• Avoid rubbing your eyes, which can make irritation worse.

• Use lubricating eye drops if needed.

• If irritation persists after rinsing, seek medical advice.

Final Thoughts

Sunscreen is essential—but it shouldn’t come at the cost of comfort. Knowing why some formulas sting and how to avoid it can help you protect your skin and keep your eyes happy. When in doubt, go for mineral options and apply with care. Your future self—and your eyes—will thank you.
