Transition Photochromic Rectangular Frame Bifocal Reading Glasses For Men Women

The upper optical area of the lens in advanced bifocal reading sunglasses is used for the far view, while the lower optical area is employed for the near view. Photochromic lenses, also known as "light-sensitive lenses," have evolved from the traditional glass lenses containing silver halide to the now mainstream photochromic resin lenses. These resin lenses incorporate spiro and other chemicals, allowing the originally colorless and transparent lenses to become tinted when exposed to bright light, providing protection and suitability for both indoor and outdoor use.

The new brand design offers a STYLE that is Suitable For Any Face, enabling you to showcase your unique and high-end taste. The comfortable, lightweight body design ensures that the glasses will not hurt your nose, and the free cleaning cloth and case keep your glasses always clean and well-protected.

With a responsible after-sale service, we promise a 30-day replacement and a lifetime warranty. In the event of any problems within 30 days, please feel free to contact our customer service, and we will provide the best solutions until the customer is fully satisfied. You can try our product with no risk.
