MAIVARDAY Men's Round Sunglasses, UV400 Protection, Lightweight, Stylish, Sun Protection, Blue Light Protection for Driving

What is blue light? Blue light is a type of visible light with a high scattering rate and high energy (blue light between 380nm and 495nm). It is also emitted by the increasingly common LED-backlit displays on computers and smartphones. Blue light has many harmful effects. To combat this, we recommend wearing blue light-blocking glasses.

Blue Light Blocking Glasses with UV400 Protection: These glasses feature high-quality blue light-transmitting lenses with high visible light transmittance and are JIS certified by the Japan Optical Inspection Association (JPO). They block harmful light from smartphone, TV, and computer screens, and offer over 99% UV protection for your eyes.

Spring Hinge: The spring hinge temples can be adjusted outward by 30 degrees to fit any face shape. The flexible adjustment naturally conforms to the contours of your face, providing a comfortable fit without feeling too tight, even when worn for long periods of time, reducing strain on your ears and temples. These sunglasses are ideal for long-term wear, such as driving, traveling, and outdoor activities.

Suitable for a variety of occasions: With just one pair, you can enjoy a variety of sports and outdoor activities, including driving, running, fishing, motorcycling, skiing, hiking, mountain climbing, and cycling. They're the perfect accessory for outdoor enthusiasts and a practical and wonderful gift.

Caution: ■ Regardless of the lens shade, 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 you may be burned by the hot frame or lenses. ■ Use a special eyeglass cleaner when cleaning. ■ Use caution when using an ultrasonic cleaner. Scratches on the surface of the sunglasses' lenses may worsen. ■ Store them in a hard case or soft pouch when not in use.
