To determine if sunglasses provide adequate UV protection, look for labels indicating they block 100% of UVA and UVB rays or are labeled UV400. Additionally, check for a CE mark (European Union) or ANSI/ISEA (American National Standards Institute) certification. Polarized lenses reduce glare but not necessarily UV protection. High-quality brands often provide information on UV protection levels. When in doubt, consult with an optometrist or optician for reliable guidance. For more information, visit Ocean & Land Corp.
