These sunglasses feature high-quality TAC polarized lenses. They effectively suppress reflected light from surfaces like roads, water, and snow, reducing glare while providing a clear view with natural color tones. The transparent, non-mirrored lenses cut down on scattered light, allowing only comfortable light to enter, which reduces eye strain. They also mitigate the glare from LED headlights of oncoming cars and streetlights, making them comfortable to use in a wide range of conditions, including sunny, cloudy, and rainy days. The frames are made of lightweight AL-MG alloy, weighing approximately 26g. They are comfortable to wear for extended periods and feature an elegant texture that resists peeling. I've used them a few times, but I'm selling them now. There are no noticeable scratches or stains, and they are in overall good condition. 【Included Accessories】 ・Dedicated case ・Eyeglass cloth 【Recommended Uses】 Driving, fishing, outdoor activities, travel, motorcycling, mountain climbing, hiking, skiing, etc. They are lightweight and comfortable to wear, making them suitable for everyday use and outdoor activities.
