Hi-Index and Polycarbonate Lenses

PLASTIC VS.
HI-INDEX LENSES

Hi-index lens material reduces lens thickness, making these lenses more comfortable and better looking by minimizing the size of visible lens edges for nearsighted wearers and reducing the magnified “bug eye” appearance associated with farsighted wearers. Essilor offers a variety of hi-index 1.67 and 1.74 lenses that are thinner and lighter than plastic—like select Eyezen™+ lenses, which are available in hi-index materials.

Polycarbonate lense technology.

LIGHTER, STRONGER, AND MORE DURABLE

Polycarbonate lenses are less likely to fracture than plastic lenses or hi-index, so they are a great option for kids' glasses. Essilor’s polycarbonate lenses are 20% thinner, 30% lighter, and 12x more impact resistant than standard plastic lenses. Anti-Glare coating—such as Crizal Sapphire® 360° UV—can be added to Essilor’s polycarbonate lenses.
