You have picked out the perfect frame for your glasses, but what about the lenses? With so many options available, the perfect lens combination can quickly become overwhelming. Our staff is trained to help you determine the best materials and options for your specific prescription and lifestyle.

Lens Types

  • Single Vision Lenses are designed to correct vision at a distance. They can also be used as reading glasses, which will correct vision up close but result in blurry distance and mid-range vision, or computer glasses, which will correct mid-range vision but result in blurry distance and near vision.
  • Lined Bifocal Lenses have powers for viewing at two distances, with a line dividing the two sections. In most situations the top of the lens allows clear vision at a distance, and the bottom of the lens allows for clear up close vision.
  • Lined Trifocal Lenses have powers for viewing at three distances, with a line dividing each section. This allows patients to see clearly at a distance through the top of the lens, intermediate/computer distance through the middle section, and up close/reading through the bottom section.
  • Progressive Lenses, also sometimes called no-line bifocals, gradually change power beginning at the top of the lens (which provides clear distance vision) to the bottom (which provides clear near vision). Progressive lenses are considered cosmetically superior to bifocals and trifocals and provide a greater range of clear vision.

Lens Materials

  • Hard Resin/Plastic is usually considered the basic lens material. It can easily be scratched, though it is typically ordered with a scratch-resistant coating. It is lightweight and can be tinted easily.
  • Polycarbonate is a thinner, lighter-weight lens than plastic and is scratch-resistant. This material is considered a safety lens, particularly for children and for safety glasses, as it is impact-resistant.
  • Trivex is a newer material on the market and considered a "mid-index" lens. It is thinner than plastic, similar to polycarbonate, and is scratch-resistant. It is also considered a safety lens for its impact-resistance. Trivex is also free from distortions or aberrations that are commonly found in polycarbonate lenses.
  • High-Index Lenses allow patients with high prescriptions to have cosmetically appealing lenses. They are lightweight, come in varying degrees of thinness compared to other lens materials, and reduce the magnification or minification of the eyes due to a high prescription.

Lens Options

  • Scratch-Resistant Coatings consist of a layer of resin that protects the lens from many surface scratches.
  • Ultraviolet (UV) Coatings are designed to filter out UV light, protecting the eye from potentially damaging UV rays indoors and outdoors.
  • Anti-Reflective (Anti-Glare) Coatings increase visual acuity because they eliminate internal lens reflections. They help to reduce glare from overhead lighting, oncoming headlights when driving at night, and computers/mobile devices (which also helps with eye fatigue). In addition, observers see the wearer, not reflections!
  • Mirror Coatings reflect some of the light striking the lens, increasing the density of the lens.
  • Photochromatic Lenses are designed to darken outside and lighten inside. The degree of darkness differs with the brand of photochromatic, and polarized photochromatic lenses are now available as well.
  • Polarized Lenses, a type of sunglass lenses, are tinted with a polarization filter and block vertical light from causing stress to the eyes. They help reduce glare from sunlight - for example, when driving, fishing, or going to the beach.
