Alphacool Photochromic Transition Glasses TR90 2 in 1 accessory

SKU CH-7FTH-BCH62

Photochromic lenses darken outdoors and clear indoors while blocking UV and blue light

  • Automatic lens darkening in bright light filters UV
  • Lenses clear indoors for sharp vision without switching glasses
  • Lightweight TR90 frame with PC front resists impact
  • Flexible TR90 temples fit different face shapes securely
  • 100 % colour reproduction from high-definition resin lenses

Product and audience

These photochromic transition glasses combine distance and near vision in one frame, automatically darkening outdoors and clearing indoors. They suit men and women who move between lighting conditions and want UV protection without swapping eyewear.

Fit and adjustment

The TR90 temples flex to fit various face shapes while integrated nose pads add stability. Lightweight PC frames and resin lenses are easy to clean, but the glasses are not reading glasses and will not correct presbyopia on their own.

Lens limits

Photochromic response depends on UV intensity, so lenses may stay lighter behind a car windscreen that blocks UV. Transition speed varies with temperature, and the coating does not replace dedicated sunglasses for extreme glare.

Questions about this item

How can I verify the photochromic transition lenses are darkening properly outdoors?

Step outside into strong light and watch the lenses darken to filter ultraviolet rays; they should return to transparency when you move back indoors or into weak light.

What comes in the box and do I need to buy a case or cleaning cloth separately?

The product is supplied as the TR90 frame with integrated nose pads and high-definition resin lenses; any case or cleaning cloth would be a separate purchase.

Are these suitable as reading glasses or only for distance and driving?

The manufacturer notes they are not reading glasses; they are photochromic far and near glasses designed for driving and varying light conditions.
