Safety Glasses Goggles for Women and Men with Bifocal Photochromic Reading Lenses

This item features advanced bifocal reading sunglasses, where the upper optical area of the lens is designed for distant viewing, and the lower optical area is dedicated to near-range vision. These sunglasses are also equipped with photochromic lenses, commonly referred to as "light-sensitive" lenses.

Traditionally, glass lenses have incorporated silver halide to achieve photochromic properties. However, the current mainstream approach utilizes photochromic resin lenses, which involve the addition of spiro and other chemicals to the acrylic resin. This allows the originally colorless and transparent lenses to become tinted when exposed to bright light, providing enhanced protection and making them suitable for both indoor and outdoor use.

The frames of these reading sunglasses are crafted from TR90, a flexible and durable material that ensures safety. This versatile eyewear can serve as a combination of reading glasses, color-changing reading glasses, and transparent UV400 goggles, providing a comprehensive solution to address various visual needs.

The lenses offer a range of magnification options, including +0, +1.0, +1.5, +1.25, +1.75, +2.0, +2.25, +2.5, +2.75, +3.0, +3.25, +3.5, +3.75, and +4.0. This broad selection allows wearers to find the perfect fit for their specific vision requirements.

The product comes in two color options: clear and blue. Both variants feature arms that are designed to accommodate a variety of face sizes, ensuring a comfortable and secure fit. Each pair of reading glasses is accompanied by a matching soft pouch, which serves to protect the lenses from scratches and enables convenient portability.

In summary, these advanced bifocal reading sunglasses combine the benefits of photochromic technology, a flexible and safe TR90 frame, and a range of magnification options to provide a versatile and practical solution for both indoor and outdoor use. The inclusion of a protective pouch further enhances the overall user experience, making this eyewear an excellent choice for those seeking a multifunctional and durable reading solution.
