Sun allergy in eyes: what to know

Polymorphic light eruption is an immune reaction that can follow ultraviolet exposure, often after skin has had less sun. The eyelids and nearby skin are delicate, so swelling, a fine rash, burning, or itch may be more noticeable there. Dry eyes, allergic conjunctivitis, infection, or another eye condition can feel similar. A clinician may need to look at the eye itself, especially if pain or vision change is present.

Move into shade and use wraparound sunglasses that block ultraviolet light. A broad-brimmed hat can protect the eyelids, while a cool clean compress may calm discomfort. Avoid rubbing the eyes and pause newly applied cosmetics or fragranced products until the area settles. If a rash keeps returning, record the timing, outdoor exposure, medicines, and products used; a dermatologist can discuss options such as carefully selected topical treatment or supervised light-based prevention. Explore [Sun Sensitivity](/symptoms/sun-sensitivity/) for related symptoms.

Get urgent medical help for severe eye pain, marked light sensitivity, blurred or reduced vision, a new halo around lights, pus-like discharge, or swelling that makes it hard to open the eye. Seek prompt advice if facial swelling affects breathing or swallowing. Arrange a routine assessment when episodes recur, involve only one eye, or do not improve after leaving the sun, because the cause may not be a sun allergy.

Ask whether the rash is on the eyelid skin or involves the eye surface, whether any medicine or cosmetic could be contributing, and which sunscreen or treatment is suitable for this sensitive area. You can also ask whether [Narrowband UVB Phototherapy](/treatments/medical-dermatology/narrowband-uvb-phototherapy/) or [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) has a role.
