The world’s first bi focal photochromic sunglasses, featuring high impact UV activated photochromic lenses.
*Available in transition from clear (Cat0) in low or no light to grey (Cat2) in full sun.
* High definition Photochromic Copper (Cat1) which darkens to
Brown (Cat3) in full sun.
* Blue Mirror (Cat3).
The bi focal magnification which is moulded discretely into the rear of the lens is available in +1.50, +2.00 and +2.50 powers.
Non magnification lenses are:
* Photochromic Clear (Cat0) which darken to Dark Grey (Cat3) in full sun.
* High Definition Copper (Cat1) which darkens to Brown (Cat3).
* Blue or Fire Red mirror which stay (Cat3).
The TR90 super light weight (less than an ounce) hybrid frame has dual moulded non slip flexible temples ideal for wearing under open or full face helmets.
The adjustable non slip nose piece ensures optimum fit and comfort for all face shapes.
The lens may not darken when under a full face helmet with the visor down as generally the visors are UV treated - but once it is raised they will darken in less than 30 seconds.
