2-In-1 Convertibles
The TrueBlue “Convertibles” styles offer you “two glasses in one” as they come with a frame-fit Photo-Stress lens to protect your vision from artificial blue light while indoors, and instantly convert to a polarized sunglass by fitting the wire-frame clip on sunglass lenses for outdoor protection. By simply pressing on the brow-bridge of the wire frame, it expands the clip for easy placement on the main frame, resulting in a customized sunglass fit.
