Vintage Sports Square Eyewear Bifocal Reading Glasses for Men

These photochromic glasses offer both beautiful styling and UV400 protection. The lenses start off clear when indoors or at night, but automatically darken to a sunglasses tint when exposed to UV sunlight. As soon as they are away from UV light, the lenses will begin to clear and become mostly clear within a few minutes. This helps protect your eyes from harmful UV radiation.

The glasses feature a bifocal design, with the upper portion of the lenses used for distance vision and the lower portion used for near vision. This makes them suitable for a variety of activities, from driving to reading.

The sports-style frame is both lightweight and durable, with a wraparound design that provides increased side protection and peripheral vision. This makes them a great choice for active lifestyles and outdoor use. The flexible, super-light frame ensures long-term comfort.

Photochromic lenses, also known as "light-sensitive lenses", work by using chemicals added to the lens material. Traditionally, glass lenses had silver halide added, but nowadays the mainstream is photochromic resin lenses, which have spiro and other chemicals added to the acrylic resin. This allows the originally colorless, transparent lenses to darken when exposed to bright light, providing protection, and making them suitable for both indoor and outdoor use.

The package includes not only the reading glasses, but also a protective case and a cleaning cloth. This ensures you can keep your investment looking and performing its best.

These glasses come with a 30-day money-back guarantee. If for any reason you encounter a problem, you can simply return them and receive a full refund, with no questions asked. This gives you the freedom to try the glasses with confidence, knowing you have no risk.

In summary, these versatile photochromic reading glasses combine style, function, and safety. The bifocal design, lightweight yet durable frame, and automatic lens tinting make them a great choice for a wide range of activities and environments. And with the added protection of the wraparound design and the 30-day guarantee, you can purchase these glasses with peace of mind.
