How thin can I process Trilogy lenses and keep good optical performance?
Trilogy lenses can be ground down to 1.0 mm center thicknesses and still retain excellent optics. Do Trilogy lenses process more like hard resin or polycarbonate products? Although they can be processed in a variety of ways, they appear to process more like polycarbonate. Can Trilogy lenses be tinted? Absolutely! You may need to experiment a little with color and time, but Trilogy lenses tint quite rapidly. Use soap and water to clean the lens prior to tinting. Do not use acetone to clean the uncoated surface because it can lead to uneven tinting. For best tint results, the surface must be properly polished. Do Trilogy lenses need backside coatings? While Trilogy lenses are not as scratch-resistant as hard resin lenses, test results indicate that Trilogy lenses have inherent scratch resistance equal to or better than many mid-index products regularly processed without a backside coating.
