Prescription lenses come in a variety of shapes and sizes. Over the years,
new technology has developed to create unique prescription lenses to correct
specific vision problems. Whileprescription glasses are most common for vision correction,LASIK eye surgery can eliminate the need for glasses.
Before you purchase your next pair of prescription lenses, educate yourself
on the many lens options.
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
Reading glasses - As we age, fine print can become more difficult to read.
Presbyopia, which causes they eyes to lose their ability to focus, is developed with
age. Reading glasses that magnify fine print can be purchased at many
stores. If the vision in each of your eyes is different, have astigmatism,
or if you require bifocal lenses, your eye doctor will need to prescribe
corrective lenses for reading.
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.
Multifocal lenses - Bifocals and multifocal lenses are a vision correction solution for those
whose vision varies based on distance. If you need one prescription to
focus on reading and another for driving or viewing at a distance, you
are likely a candidate for multifocal lenses. Progressive lenses, also
called “no-line bifocals,” provide a gradual shift in prescription
strength, without a visible line in the lens.
Polycarbonate protective lenses - For athletes, protective eyewear can prevent up to 90% of sports-related
eye injuries. Polycarbonate plastic lenses 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.
