A Guide to Prescription Eyewear Options

polarized lenssmPrescription lenses come in a variety of shapes and sizes, and the frames
and lenses are manufactured from a number of different materials. Over
the years, new technology has developed to create unique prescription
lenses to not only correct specific vision problems, but designed to address
various lifestyle tasks and to be more durable. Before you purchase your
next pair of
prescription eyeglasses or sunglasses, educate yourself on the many lens and frame options available.

Lens options and add-ons

  • Computer lenses – Designed to reduce glare for individuals who spend long periods of time
    in front of their computer screen. Computers can cause the eyes to strain
    when trying to focus on electronic words and images. Eyewear with anti-reflective
    coating and a tint can help reduce glair from the computer screen and
    overhead lighting.
  • High-index lenses – The days of thick, “coke-bottle” lenses are gone. Thanks to
    new technology, even many of the strongest vision prescriptions can be
    put into thinner, lighter high-index lenses. Aspheric lenses are another
    option for individuals with strong prescriptions. Aspheric lenses are
    thinned on the sides to avoid thickness of the lens.
  • Polycarbonate and Trivex lenses – For athletes, protective eyewear can prevent up to 90% of sports-related
    eye injuries. Polycarbonate plastic lenses and Trivex lenses are lighter
    and are 10 times stronger than other lenses, and better able to withstand
    direct contact during sports like racquetball, hockey and baseball.
  • Colored lenses – Lenses tinted with yellow are popular with skiers, snowboarders, cyclists
    and other athletes as they are known to help produce a sharper image in
    low light. Green-colored lenses are worn by many golfers and are thought
    to heighten contrast, making the white ball stand out against the green.
  • Polarized lenses – Designed to reduce glare from reflected surfaces. Sunglasses with polarized
    or mirrored lenses are popular with boaters, water skiers and snow skiers
    as they limit light coming into the eye in bright conditions.
  • Anti-reflective lenses – The anti-reflective coating is a popular add-on. This option reduces lens
    reflections that interfere with eye contact and glare that can inhibit
    night vision.
  • Lens coatings – There are several other lens coating options available, such as scratch-resistant
    coating, anti-fog coating and UV-blocking lens coating.

Frame options

  • Hypoallergenic frames – Most frames are made of plastic or metal, but if you suffer from skin allergies,
    you may need hypoallergenic frames, which are made of materials such as
    titanium or stainless steel. These materials will help avoid contact dermatitis
    caused by skin allergies.
  • Snap together frames – If you’d like the option to change the frame style based on your
    outfit and accessories, you may like eyeglass frames that snap together,
    allowing you to “mix and match” the temple pieces with the
    front frames.
  • Flexible frames – Especially beneficial for the active person, frames that are made to be
    flexible, or that are made with spring hinges are more durable and will
    reduce the potential for breakage.

In addition to these lens and frame options, ask your eye doctor about
eyewear designed for specific sports. Performance sunglasses, diving masks
and swim goggles, ski goggles, shooting glasses and safety goggles are
examples of other eyewear options available.
