High Index 1.74 Lenses: Ultra Thin Prescription Glasses

Why Is a 1.74 High Index Lens Right For Me?

High Index Lenses are an advanced type of optical lens that provides higher prescription wearers with a slimmer and more streamlined shape. You no longer have to worry about lacking a stylish frame, and low profile lens, just because you have a high prescription. Perfect for anyone with +/- 2 prescriptions or higher, RX-Safety uses Younger Optics lenses made of high-tech plastics, which keeps them strong and affordable. 

Our 1.74 lenses are the highest index you can currently get on the market, without changing to a more expensive and rigid material. RX-Safety also now offers these lenses in Transitions Gray and Brown so you can see safely in the sun while you work or play.
