Eyeglass Lenses

A brief description of the types of lenses available at Vision Source Eye Center of the Triad in Greensboro.

With so many lens options available, it can get very confusing. That’s why Vision Source Eye Center of the Triad provides trained professionals to help ensure you get the lenses to match your needs. Below are just some of the options our professional opticians will discuss when you visit.

Lens Style

The first decision to be made is which lens style fits your needs. The three main lens styles used today are single vision lenses, multifocal lenses, and occupational lenses.

  • Single Vision Lenses: A single-vision lens, also sometimes called a “unifocal lens”, is a lens that has the same power of correction across its whole surface. It can be used to correct “simple” vision defects such as myopia, hypermetropia, and astigmatism. Examples of single vision lenses are lenses that correct for distance only or readers.
  • Multifocal Lenses: Multifocal lenses are lenses that have more than one prescription. The most common multifocal lenses are bifocals and progressives. Bifocal lenses provide a distinct near and far viewing area, but no intermediate area (3-20 feet away). The different viewing areas are separated by noticeable lines that can be awkward, abrupt, and frustrating to the wearer. With progressives you get smooth, continuous vision at near, middle, and distant focal ranges, with no lines or unsettling image jumps. In today’s technology driven society, most patients prefer the progressive lens design to the bifocal design.
  • Occupational Lenses: Occupational lenses come in different styles and offer solutions to many different problems. Most patients spend a great deal of time at the computer today and benefit from specific computer progressive lenses with larger computer and reading areas than a standard progressive lens. We also prescribe Anti-fatigue lenses for patients who don’t yet need a full progressive, but often develop eye fatigue after working on a computer or reading all day. This lens has a small bump of power to help ease tension in the eye and create a more comfortable experience. Have a conversation with one of our optometric technicians, doctors, or opticians to learn more about the many occupational lens options available.

Lens Materials

In the past, eyeglass lenses were made exclusively of glass. Today, most eyeglasses are made of high-tech plastics. These new lenses are lighter, do not break as easily as glass lenses, and can be treated with a filter to shield your eyes from damaging ultraviolet light.

  • Polycarbonate lenses: These eyeglass lenses are impact-resistant and are a good choice for people who regularly participate in sports, work in an environment in which their eyeglasses may be easily broken, and for children who may easily drop and scratch their eyeglasses. Polycarbonate lenses also provide ultraviolet protection.
  • Trivex lenses: These lenses are made from a newer plastic with similar characteristics of polycarbonate lenses. They are lightweight, thin, chemical resistant and impact-resistant and may result in better vision correction than the polycarbonate lenses for some people.
  • High index plastic lenses: Designed for people who require strong prescriptions, these eyeglass lenses are lighter and thinner than the standard, thick “coke bottle” lenses that may otherwise be needed.
  • Blutech lenses: BluTech indoor lenses provide protection from sources of harmful high-energy blue light, such as harsh fluorescent lighting, computer screens, and personal electronics, while also giving you soothing vision.
