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. (Essilor.com)
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. (essilor.com)

With ordinary plastic lenses, a strong prescription can result in a thicker lens. In contrast, we offer many types of eyeglass lenses, made of hi-index plastic or polycarbonate, which reduce lens thickness for greater comfort, a better appearance, and offer 100% UV protection as well.
Hi-index plastic is lightweight and thinner than most plastic. Essilor offers hi-index 1.67, 1.6, and 1.74 lenses that are thinner and lighter with more appealing aesthetics for greater comfort and a better look.
Polycarbonate lenses have superior impact resistance and are lighter than regular plastic lenses. Our eyeglass lenses are 20% thinner and 30% lighter than standard plastic lenses, yet super tough and very hard to break.
ADDITIONAL FEATURES & TREATMENTS
For every type of eyeglass lens, one or both sides of the lens can be treated to extend the longevity of the glasses and improve clarity of vision. Some of our advanced lens treatment options include the following:
Anti-Glare coatings—reduces reflections, allowing more light to pass through your lenses for better clarity, especially at night. Anti-glare coatings also help lenses look nearly invisible, reducing distraction and improving eye contact. Crizal® coatings and Xperio® polarized lenses provide this feature by reducing the effects of glare, as well as protecting against scratches and smudges.
UVA and UVB blocking—can help protect your eyes from the sun's damaging ultraviolet rays. Xperio® lenses, Transitions® lenses, and Crizal® coatings offer protection for your best vision under the sun.
Transitions Light Intelligent Lenses™—lenses that adjust from clear to dark, and every shade in between.
Polarization—a special filter that blocks intense reflected light. Xperio® polarized lenses eliminate blinding glare so you can see the outside world with sharper colour and greater depth.
