With this beautiful weather, your sunglasses are a must-have. But they might not protect your eyes as effectively as you think. Brazilian scientists warn that sunglasses have an expiration date for their UV protection.
Sunlight gradually degrades the UV-blocking properties of your lenses. To ensure optimal protection, experts recommend replacing them every two years. In tropical regions, where sunlight is more intense—even in winter—sunglasses may degrade faster.
While your pair might last longer than two years, prioritizing eye health means staying proactive. It's the perfect reason to invest in a fresh set.
