Bifocal Glasses for Mountain Biking with Photochromic Lenses Model TIGER SUN READING
How many times have you found it difficult to read your GPS, heart rate monitor, or speed computer during your running or cycling sessions? DEMON has considered all athletes who struggle with this issue during their performances, creating the TIGER SUN READING. These bifocal mountain biking glasses feature photochromic lenses and are equipped with a graduated bezel on the underside of the lens, allowing users to read even the smallest screens with ease.
The wide field of vision allows you to use them like regular sports glasses, utilizing the bezel only when necessary. The TIGER SUN READING represents the evolution of sports bifocal glasses.

Description
The frame features an aggressive and trendy design, crafted from TR90—a special blend of nylon and carbon fiber that makes our cycling glasses 20% lighter than conventional materials while enhancing resistance to accidental impacts, traction, and stress. This material offers high resistance to chemical agents and is biocompatible, making it safe for prolonged skin contact.
Adjustable hypoallergenic rubber nose pads ensure a secure fit for every facial shape. Rubberized grips on the temples gently wrap around your head, preventing micro-slips caused by vibrations on the road.
The lenses are made from high-quality polycarbonate, providing UV protection and exceptional clarity. Their anti-breakage, decentralized, and optically perfect nature enhances visibility and safety.
The bifocal sports glasses TIGER SUN READING come with lenses available in various strengths: +1.5, +2.0, and +2.5.
The photochromic lenses automatically adjust their tint based on UV radiation or sunlight, darkening in bright conditions and lightening in darker environments. This automatic adaptation ensures continuous optimal visibility during varying light conditions, supporting uninterrupted performance.
