FROM ORDINARY LENSES TO EXTRAORDINARY TECHNOLOGY
The Transitions photochromic technology becomes an integral part of the lens through one of two specialized processes.
One process is called imbibing. Derived from the Latin word imbibere meaning, to drink in, this method uses heat to draw the photochromic dye into the lens itself. After the imbibing is complete, a scratch-resistant coating is applied to the surface of the lens.
A number of lens materials do not imbibe readily. In these cases another method called Trans-Bonding™ is used. Where imbibing places the photochromic technology below the lens surface, the patented Trans-Bonding puts the photochromic technology on the lens surface.
Both the imbibing and Trans-Bonding methods provide the same uniform tint colour, regardless of lens thickness differences caused by lens prescriptions. At Transitions Optical we develop and adapt our processes for optimum photochromic performance, lens durability and compatibility with other lens treatments like anti-reflective coating.
