Austria Experts Warn of Eye Damage and Expired Sunscreen Risks This Summer

Prim. Felix Buder, head of ophthalmology at the Pyhrn‑Eisenwurzen Klinikum in Steyr, explains that UV‑A and UV‑B radiation can irritate the eyes, cause painful conjunctivitis and, over time, raise the risk of cataracts and retinal changes. He advises using sunglasses with a verified UV‑400 filter, especially for children, people with light eyes, and anyone spending time outdoors in reflected sunlight such as on water or in the mountains.

Consumers are also reminded to check the PAO symbol on sunscreen tubes, which indicates how many months the product remains effective after opening—typically twelve months. After this period, UV filters degrade, reducing protection and potentially increasing skin‑cancer risk. Visible signs of spoilage such as off‑odors, texture changes, or discoloration also signal that the sunscreen should be discarded. Proper storage away from heat and light prolongs product life.
