Introduction: The smart glasses of the future
In a world where we spend hours a day staring at screens and are exposed to constantly changing light conditions, the need for functional accessories is growing. This is where non-prescription photochromic blue light filtering glasses come into play: They combine style, health protection, and technology in a unique way.
1. What are photochromic lenses?
Photochromic lenses react to UV light – they automatically tint in sunlight and remain clear indoors. The tint is based on molecules such as spiropyran or naphthopyran , which change their structure when exposed to UV radiation.

2. What does the blue light filter do?
Blue light filters block HEV (high-energy visible light), which is primarily emitted by screens. Too much of this can disrupt sleep and cause eye strain.
