Lens Designs

Our optician considers the design and function for every type of eyeglass lens. Does the wearer need them to see far away or up close? Are we correcting a vision problem, such as astigmatism? Here are just some of the lens designs to meet those vision needs.

  • Single vision lenses—These lenses are made for one focal power to correct a single vision need. This can be for distance correction, reading, or computer glasses.
  • Bifocal lenses—Bifocal lenses help you see near and far objects clearly in one set of glasses. The visible line helps you know where to look and provide a wide area for reading. Bifocals do not correct for intermediate vision, which is for computer use.
  • Trifocals—Trifocal lenses look and perform similar to bifocal lenses, with an added viewing zone to help correct vision in the intermediate field. They have two visible lines where the viewing zones change.
  • Progressive lenses—A Progressive lens has multiple prescriptions for all three areas of vision, but without visible lines. Progressive lenses gradually change prescription power as you look up and down.

Materials

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 and a better appearance.

  • Hi-index plastic is lightweight and thinner than most plastic. We offer hi-index 1.67 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

  • Anti-reflective coating— These help reduce reflections, allowing more light to pass through your lenses for better clarity, especially at night. Anti-reflective coatings also help lenses look nearly invisible, reducing distraction and improving eye contact. Crizal® lenses provide this feature by reducing the effects of glare, as well as protecting against scratches and smudges.
  • UVA and UVB blocking—Lenses with UV blocking help protect your eyes from the sun's damaging ultraviolet rays. Xperio UV lenses, Transitions® lenses, and Crizal lenses offer protection for your best vision under the sun.
  • Adaptive Lens Technology—This feature allows eyeglass lenses to automatically adjust from clear indoors to dark outdoors. With Transitions Light Intelligent Lenses™, you get just that—lenses that adjust from clear to dark, and every shade in between.
  • Polarization—a special filter that blocks intense reflected light. Xperio UV polarized lenses eliminate blinding glare so you can see the outside world with sharper color and greater depth.
