There are several different kinds of lenses available, and each has their advantages.glasses

  • Plastic– The most inexpensive lenses we have. They are not scratch proof, but are lighter than glass.
  • Polycarbonate– A lighter, thinner material that is scratch-proof
  • Crizal– These almost invisible lenses are extremely durable, scratch resistant, and very easy to clean. Newest technology, non-glare properties are joined with double-sided scratch protection and a finish that repels water. Crizal lenses remove reflections that cause eyestrain and fatigue, especially from fluorescent lighting and computer screens. They resist dust and smudges, so you do not have to clean them as often.
  • Transitions– lightweight plastic lenses that feature a scratch-resistant coating, UV filter, and a special tint that quickly changes in response to various light changes.
  • Single vision– For eyeglass wearers who only need one type of correction. There is only one prescription in these, so it either corrects nearsightedness or farsightedness.
  • Bifocal– Eyeglasses with two ocular powers and a distinct line separating them. It corrects two different prescriptions in one pair of glasses.
  • Trifocal– Eyeglasses where the lenses have 3 regions to correct for distance, intermediate, and near vision.
  • Progressive– Perfect for people who don’t like to switch from reading glasses to distance vision eyeglasses. Progressive glasses are the clear choice for distance and reading vision because there is no definitive line like the line seen in bifocal prescription eyeglasses.
  • High index– Lenses that take the thickness out of strong prescriptions
  • Aspheric– Help to reduce both lens thickness and “magnification” in strong prescriptions, so that your eyes appear more normal in size.
  • Anti-reflective coatings– Cut glare for activities such as working at a computer or driving at night, and enhance the appearance of eyeglasses by making lenses almost invisible.
