This is one of the thinnest and flattest lenses in its power range and it also has the highest index among lenses currently manufactured in the Optical Industry. The smooth curve over the entire surface of the lens creates a more aesthetically pleasing effect; it makes the wearer’s eyes look more natural.

· Advantages of 1.74
· Super Hydrophobic coating
This special water and oil-repellent coating is layered on top of the hard multi-coating which is an
upgrade from conventional hydrophobic coating.
· Super Hydrophobic Ep coating
The surface is covered with a special thin layer of vinyl (causing it to be slippery) to enable precision
processing of prescriptions while protecting the lens from contamination during shipping and storage.
· Primer coating enables 1.74 lenses to be stronger and more resistant to impact.
· Edge thickness by index
· Edge thickness comparison
