The following is

1. What is
presbyopia?
Presbyopia is a natural, easily
correctable part of aging that effects all adults sometime after the age
of 40. Presbyopia leads to difficulty in reading, sewing, and other
daily near point tasks. To read more about presbyopia, click here .
2. How do
I know what strength I need?
The best way to determine the correct
strength is to have an eye exam. If you do want to select a strength,
start by selecting a low strength. You should see printed
material clearly at a distance of about 14 inches from your eyes.
If the print is not clear, you can increase the strength
in .25 increments until it is at the 14 inch range.
The important thing to remember is to stop when the print
becomes clear and not to use too much magnification.
3. What are diopters?
Diopter is the unit of measurement for lenses, which measures the refractive
power of a lens. Ready-to-wear reading glasses come in diopters ranging from +0.75
to +4.00. The higher the diopter, the higher level of
magnification.
4. What are aspheric lenses?
Lenses that are curved flatter than normal (spherical) lenses. Aspheric
lenses are lighter weight, reduce distortion, and do not magnify your
eye.
5. What is the difference
between ready-to-wear reading glasses and prescription glasses?
The main
differences are that ready-to-wear readers have the same prescription in both lenses.
Also, the optical centers of the lenses are not placed individually
for each wearer.
6. Can I wear readers over my
contacts?
Yes, many individuals prefer to use readers
and contacts rather than using a progressive lens of bifocal.
7. Will I
still need reading glasses after laser vision
correction?
Yes, laser vision procedures known as
LASIK and PRK will correct for myopia (nearsightedness), hyperopia
(farsightedness), and astigmatism but not presbyopia.
