MAIVARDAY Men's Polarized Photochromic Sunglasses with UV Protection for Sports, Driving, Baseball, Golf, Running, Outdoor Activities, Fishing, and Mo

Open/Close Frame: The flexible closure allows for a natural fit to the shape of your face. It's not too tight, so it doesn't feel too tight, even when worn for long periods of time, and it doesn't put strain on your ears or temples. Ideal for extended wear, such as driving, traveling, and outdoor activities. Photochromic Lenses: Enjoy two different views with one pair. The photochromic lenses darken in bright light and clear in dark conditions, keeping your eyes looking their best. Protect your vision in any lighting environment and reduce eye fatigue. Note: The photochromic effect may be weaker in areas with low UV radiation, such as indoors or overcast skies. TAC Polarized Lenses: TAC polarized lenses effectively filter out reflected light from roads, water, snow, and other surfaces, providing a comfortable, clear view. The TAC material is lightweight, durable, and resistant to scratches and breakage. This allows for safe use in everyday wear and harsh outdoor environments. UV400: TAC polarized lenses block 100% of UV rays (UVA/UVB), providing effective protection from harmful UV rays. This protects your eyes even during extended outdoor activities. Caution: ■ Regardless of the lens tint, do not look directly at strong light, such as sunlight or welding light. ■ Do not store sunglasses in places where temperatures exceed 60°C (140°F), such as inside a car in the hot sun, in a sauna, or near a stove or heater, as there is a risk of burns from the hot frame or lenses. ■ When cleaning, use a detergent specifically designed for glasses. ■ Be careful when using an ultrasonic cleaner. If there are scratches on the surface of the sunglasses lenses, they may worsen. ■ When not in use, store them in a hard case or soft pouch.
