Eyeglasses and Your Eyes
 Eyeglasses
today are fashion accessories, as stylish as purses and belts. In fact,
you'll find familiar names – Gucci, Vera Wang, and Calvin Klein just to
name a few - on your choice of frames these days. So don't fret if contact
lenses irritate your eyes. Instead, scope out the latest fashion frames at
Total Family Eyecare to give your face a fresh look.
What Types of Lenses Are Available?
As technology advances so, too, do eyeglass lenses. 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. The following modern eyeglass lenses are
lighter, thinner, and more scratch-resistant than glass lenses or the
older, common plastic lenses. All eyeglasses and lenses are warranted for
two full years.
* Polycarbonate lenses. These eyeglass lenses
are impact resistant and are a good choice for all children, people who
regularly participate in sporting activities, or work in a job environment
in which their eyeglasses may be easily scratched or broken.
* Transitions and tinted lenses. Made typically from polycarbonate
or plastic, these eyeglasses change from clear to tinted when exposed to
sunlight. This eliminates the need for prescription sunglasses.
* 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.
* Aspheric lenses. These eyeglass lenses are unlike typical lenses,
which are spherical in shape. Aspheric lenses are made up of differing
degrees of curvature over its surface, which allows the lens to be thinner
and flatter than other lenses. This also creates an eyeglass lens with a
much larger usable portion than the standard lens.
What Are Multifocal Eyeglass Lenses?
People who have more than one vision problem (for example, have difficulty
seeing both far away and up close) often need eyeglasses with multifocal
lenses. Multifocal lenses, such as bifocals, trifocals, or progressives,
are eyeglass lenses that contain two or more vision-correcting
prescriptions. In years past, you could spot a multifocal lens by the line
separating the two sections. But today multifocal lenses can be made to
look seamlessly attractive. No one but you and the doctor will ever know!
Bifocals. Bifocals are the most common type of
multifocal lens. The eyeglass lens is split into two sections; the upper
part is for distance vision and the lower part for near vision. They are
usually prescribed for people over the age of 40 whose focusing ability
has declined due to presbyopia.
Trifocals. Trifocals are simply bifocals with a
third section used for people who need help seeing objects that are within
an arm's reach.
If you have questions about which eyeglass lens is
right for you, talk to Dr. Lampert or Dr. Sheiner. They can help you
choose the lens that best fits your lifestyle and vision needs.
How Should You Care for Your Eyeglasses?
* Always store eyeglasses in a clean, dry place away from potential
damage.
* Clean your eyeglasses with water and a non-lint cloth, as necessary, to
keep them spot free and prevent distorted vision.
* See Dr. Lampert or Dr. Sheiner annually to check your eyeglass
prescription. Remember, eyeglasses can correct most common vision
problems simply, without surgery, eye drops or fuss.
