Transition Bifocal Reading Glasses Photochromic Gray Eyeglasses

This item consists of Photochromic Gray Bifocal Reading Glasses. The top portion of the lens is clear, while the bottom section offers a range of magnification options to suit your reading needs, whether you're perusing a book, newspaper, or magazine. These versatile lenses adapt to your environment, transitioning from indoor reading glasses to outdoor reading sunglasses as the light conditions change. They also function as standard photochromic sunglasses, providing comprehensive radiation and UV protection.

The Bifocal Gradient Glasses Readers feature a frameless, titanium construction that offers UV400 protection and anti-radiation properties. The dimensions of the frames are 127mm (5.0 inches) wide, with 138mm (5.4 inches) arms and 52x31mm (2.0x1.2 inches) lenses.

The Transition Photochromic Gray Bifocal Reading Glasses utilize optical glass containing silver halide microcrystals. This technology enables a photochromic, reversible reaction that causes the lenses to darken under sunlight and UV irradiation, absorbing both ultraviolet and visible light. Once the light source is removed, the lenses gradually restore to a colorless, transparent state.

The photochromic properties of these glasses are triggered by the presence of sunlight and UV radiation. In bright, outdoor conditions, the lenses will darken, shielding your eyes from glare and harmful UV rays. When you transition indoors or to less-illuminated environments, the lenses will gradually revert to a clear state, allowing you to read comfortably without the need for prescription eyeglasses.

This versatile design caters to a wide range of lighting conditions, ensuring you can enjoy clear, unobstructed vision whether you're outdoors or indoors. The bifocal feature further enhances the reading experience, providing the necessary magnification for close-up tasks while maintaining a clear, uninterrupted view of your surroundings.

The combination of photochromic technology, bifocal lenses, and a lightweight, durable titanium frame makes these reading glasses a practical and adaptable choice for individuals who value convenience, comfort, and eye protection. Whether you're an avid reader, a frequent traveler, or simply someone who appreciates the benefits of versatile eyewear, these Photochromic Gray Bifocal Reading Glasses offer a comprehensive solution to your visual needs.
