Ophthalmologist warns counterfeit sunglasses can cause permanent eye damage

An ophthalmologist has warned that a large share of sunglasses sold during the summer months lack adequate ultraviolet protection and can cause lasting eye damage. Dr. Sinan Göziyev said consumers should look for products labeled UV400, 100% UV protection, or carrying a CE mark. Göziyev noted that ultraviolet exposure accumulates without being noticed, with roughly 80% of a person's lifetime UV dose received by age 18. He said short-term risks include retinal burns and photokeratitis, which can develop within hours, while long-term effects include cataracts, age-related macular degeneration, and cancers around the eye. The specialist cautioned that dark-tinted lenses can dilate the pupil, allowing more harmful radiation to enter the eye. He recommended Class 2, 3, or 4 filters depending on use, and noted that polarized lenses reduce glare but do not provide UV protection on their own. Göziyev advised buying sunglasses only from optical stores, where lens quality and warranty documents can be verified.
