Sunscreen application is a necessary practice for protecting the skin from damaging ultraviolet (UV) radiation, but it often leads to a common and uncomfortable side effect: stinging or burning eyes. This irritation happens when the product migrates into the delicate mucosal membranes of the eye, typically due to sweat, water, or accidental rubbing. The immediate discomfort, which can include watering, redness, and temporary blurry vision, frequently causes people to skip applying protection to the sensitive skin around their eyes altogether. However, the skin surrounding the eyes is thin and highly susceptible to sun damage, making protection in this area particularly important for long-term skin health.
Selecting Sunscreen Formulas for Sensitive Areas
The primary reason sunscreen causes eye stinging is the presence of certain chemical UV filters in the formula. Ingredients like avobenzone, oxybenzone, octinoxate, and homosalate are known irritants when they come into contact with the eye’s surface. Even if the product is not applied directly near the eye, these ingredients can easily migrate with the skin’s natural oils and moisture.
A better option for the eye area is a mineral, or physical, sunscreen formula. These products use zinc oxide and titanium dioxide as active ingredients, which work by sitting on the skin’s surface to physically block and reflect UV radiation. Because these mineral compounds are inert, they are less likely to cause stinging if they accidentally enter the eye. Look for products labeled for sensitive skin or those that come in a thicker stick or balm format, which helps keep the formula stationary.
Proper Application Techniques to Prevent Migration
Applying the product correctly is important to prevent migration into the eyes. Start by applying a small, precise amount of sunscreen only to the bony ridge around the eye socket, known as the orbital bone. Avoid placing any product directly on the eyelid or too close to the lash line, as movement and blinking will naturally cause the product to spread.
Use a gentle patting or dabbing motion instead of vigorous rubbing to ensure the formula stays in place. For better control, consider using a separate sunscreen stick, which is thicker and less likely to flow than a liquid or cream. Allow the sunscreen several minutes to fully set and dry before engaging in activities that cause heavy sweating or swimming. Wearing physical barriers, such as UV-blocking sunglasses and a wide-brimmed hat, offers additional protection for the orbital area.
What to Do If Sunscreen Enters the Eyes
If you experience stinging, immediate action can help minimize discomfort and irritation. The first step is to avoid rubbing your eyes, as this can spread the sunscreen residue and worsen the irritation. Instead, gently flush the eyes with cool, clean, lukewarm water for several minutes.
You can use a clean cup to pour a steady, gentle stream over the open eye, or hold your head under a low-pressure faucet or showerhead. The goal is to dilute the irritating chemicals and wash them away from the eye’s surface. After flushing, artificial tears or lubricating eye drops can soothe the eye and rinse out any remaining particles. If the pain, redness, or blurred vision persists after rinsing, seek medical attention.
