In bright sunlight outdoors, they become dark like sunglasses, reducing glare. On the other hand, in spaces without UV light, such as indoors, they become clear lenses like regular eyeglasses, ensuring a bright field of vision. 【What are Polarized Lenses?】 Recommended for fishing, motorcycling, cycling, etc. Highly recommended for all marine sports, winter sports such as skiing and snowboarding, dealing with glare on golf course greens, and for strong summer sun or winter snow glare. ● Color Black Frame Light Gray (Smoke) Lenses ● Size Lens width 48 / Bridge width 15 / Temple length 148 / Front width 138 / Height 48 (mm) ● Material Plastic ● Condition Unused, New Please refrain from purchasing if you are sensitive about condition. ● Comes with a soft case for simple storage.
