These are polarized sunglasses. Thank you for viewing. [Product Description] Have you ever been bothered by strong sunlight, wind, or the discomfort of debris getting into your eyes? Securing your vision and protecting your eyes safely are essential for outdoor activities such as fishing, skiing, and driving. This product is an over-the-glasses type of polarized glasses that can be worn over your regular eyeglasses. The full-coverage design prevents direct sunlight and dust from entering, ensuring a comfortable field of vision. With UV400 protection, the UV cut performance is perfect. It reduces eye strain even during long outdoor activities. The polarized lenses suppress reflected light, reducing glare on the water surface when fishing and allowing you to spot fish shadows. For driving, racing, and cycling, they reduce road reflections, sunlight, and the glare from headlights of oncoming vehicles at night, improving visibility. The frame is made of lightweight plastic material, designed for comfort even during long wear. As long as your eyeglasses fit within the compatible size, you can wear them without changing glasses. The full-coverage design also guards against light and debris from the sides. You can feel secure in situations where sand or snow might fly, such as during climbing or skiing. This one product solves the problems of "light and wind leaking from the gaps with regular sunglasses" and "not wanting to take off my glasses." Please experience the practicality and peace of mind for all outdoor sports. --- [Compatible Situations] Mountaineering / Fishing / Skiing / Racing / Driving / Cycling / Climbing / All other outdoor sports --- [Materials] Material: Plastic [Available Sizes and Colors] Size: Height 45mm / Width 145mm / Depth 155mm (Compatible eyeglass size: Height 38mm / Width 140mm or less) Color: Frame = Black, Lens = Yellow or Gray *Note: We cannot accept size or color changes after purchase. *The size and color of the actual product delivered will be as stated in the product name. --- [Shipping Information] We will ship for free.
