Adafruit 2-in-1 Photochromic Glasses
These glasses combine blue-light filtering with photochromic lenses that darken outdoors and clear indoors. They are built for anyone who spends long hours at a screen and also steps outside regularly. The TR90 frame with metal hinges keeps the weight low and the fit secure.
Indoor workers who also face bright sun
Suitable for office staff, students or remote workers who want one pair for desk work and daylight commutes. Not intended for buyers who need prescription correction, specialised safety ratings or polarised lenses for driving glare. The bifocal area carries zero magnification top and bottom.
8-second photochromic transition
The lenses shift from clear to grey in roughly eight seconds when exposed to UV sunlight, then fade back quickly inside. This single speed figure tells you whether the reaction matches your daily moves between indoors and out.

Questions about this item
How much heat do the TR90 frames and photochromic lenses generate when worn all day?
The ultra-light TR90 material and photochromic lenses produce no measurable heat during extended wear.
What prescription lenses must I already own for the 0-degree bifocal sections to work?
The lenses carry 0 diopter power above and below the bifocal line, so no prescription lenses are required for them to function.
Will the 8-second colour change still activate if I keep older UV-coated prescription glasses underneath?
The photochromic layer reacts directly to ultraviolet sunlight; any UV-blocking layer beneath it will prevent the lenses from darkening.
