Conversion offers a fast and seamless shift between tinted and clear allowing Conversion to compete with the market leading photochromics. Conversion’s photochromic properties are in-mass, which means that its quality performance will stay truer longer. The special monomer used will not yellow over time, unlike the lenses that use coatings. Additionally, the use of a monomer solution retains the shift-speed (rate from light to dark and back to light) longer than coatings that start to decrease their shift-rate as soon as after six months of use.
