Yet studies reveal that many popular sunglasses fail to meet safety standards, potentially increasing rather than reducing eye damage. Protecting your vision in summer starts with understanding how to choose sunglasses that offer real protection—not just style. Studies have found that the pass rate of sunglasses sold on the market is less than 10%, and the failure to provide protection may cause more damage to the eyes.

But according to a new study published shows that only 1 in 12 sunglasses on the global market meet basic safety standards for ultraviolet (UV) protection. This means that what many consider a routine accessory might be giving a false sense of security, leaving eyes vulnerable to severe damage. UV radiation, particularly UV-A and UV-B, doesn’t just harm the skin. It can damage the cornea, lens, and even the retina, contributing to cataracts, macular degeneration, and photokeratitis—commonly referred to as “sunburn of the eye.” The more exposure accumulates over time, the higher the risk for long-term vision loss. Unfortunately, price and lens darkness are not reliable indicators of safety. Experts from the American Academy of Ophthalmology emphasise that even inexpensive drugstore sunglasses can offer complete UV protection, as long as they are clearly labelled “100% UV protection” or “UV400.” In contrast, luxury sunglasses without proper labelling may provide minimal protection. Another related study warns that dark lenses without UV filters can be especially harmful. Because they cause the pupil to dilate, more harmful rays can enter the eye, increasing the risk of internal damage. Additionally, children and women may be more susceptible to UV-related eye issues due to thinner ocular tissues and more time spent outdoors without adequate protection. To properly evaluate sunglasses, check for UV400 certification and ensure they cover the entire eye area. Oversized frames or wraparound designs provide extra protection by reducing peripheral UV exposure. While polarised lenses reduce glare, they do not guarantee UV protection unless stated explicitly. Symptoms of acute UV eye damage include redness, dryness, tearing, and a gritty sensation—similar to having sand in your eyes. In severe cases, exposure can lead to photokeratitis, which may cause blurred vision and extreme discomfort for up to 48 hours. Nearly 90% of people wear sunglasses, but they don’t know how to choose ones that can truly protect against UV rays.

Regular eye exams are also essential, especially for individuals with high sun exposure or early signs of eye strain. As temperatures and UV indexes climb, protecting the eyes is as critical as applying sunscreen. A good pair of sunglasses is not just about comfort or aesthetics—it is an essential part of daily health maintenance.
