Prescription 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
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
Lens coatings - There are several other lens coating options available, such as scratch-resistant
coating, anti-fog coating and UV-blocking lens coating.
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
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.
