How eyeglasses work
Eyeglasses improve vision by refocusing light to the eyes in a way
that will counteract a visual impairment. Lenses are shaped according to the
vision problem.
Frame and Lenses Options
A variety of lens and frame options gives consumers the choice of
glasses that are both practical and attractive. Frames available in many
styles, shapes, and colors fit practically every personality. The plastic
lenses of today are lighter, thinner, and more durable than the glass lenses of
yesterday, and they can even contain special filters to block ultraviolet light.
Common types of lenses include:
- Polycarbonate lenses – Durable lenses able to withstand harsher use
- Photochromic & tinted lenses – Clear when out of sunlight, tinted within. Takes the place of both regular eyeglasses and prescription sunglasses.
- High index plastic lenses – Relatively light and thin glasses for higher prescriptions
- Aspheric lenses – Exceptionally thin and flat lens providing a large useable area
If you need to correct several vision impairments, you can get
multiple prescriptions in one pair of glasses. Multifocal lenses such as
bifocals (2 prescriptions) or trifocals (3 prescriptions) can be crafted
without seams so that they look like ordinary lenses.
Care of Eyeglasses
To ensure the maximum use of your eyeglasses, keep them in a clean,
dry, and safe place; clean them; and make yearly visits to the optometrist to
check their prescription.
How Can I Save Money on Vision Care?
Proper vision care is vital for both adults and
children, yet it is often overlooked because of the cost. You may be able to save a substantial amount of money through an insurance program, such as the vision plans offered through HumanaOne.
