Hey parents, let's talk about protecting those young eyes in style! These LIU·WEN sports sunglasses are specifically designed for active kids aged 4-12 who love being outdoors. The polarized lenses provide 100% UVA/UVB protection while reducing glare and improving contrast - super important for sports and beach days. The frame is made from soft, flexible silicone that's basically unbreakable, which means they can handle rough play without snapping. The included head strap keeps them securely in place during running, cycling, climbing, or any high-energy activities. The medium tint lenses allow about 20% light transmittance, so they're perfect for bright conditions without being too dark. Measurements are: lens width 57mm (2.24\), lens height 37mm (1.46\), bridge width 22mm (0.87\), frame width 115mm (4.53\), and arm length 118mm (4.65\). They come in various fashionable colors that kids actually want to wear, and the durable construction stands up to extreme outdoor conditions. We're so confident in the quality that we offer a 30-day money-back guarantee - no questions asked. Whether your child is into baseball, beach days, skiing, or just playing outside, these sunglasses provide both outstanding protection and cool style that'll make them excited to wear them.
