 The following is a list of common questions regarding
reading glasses. If this page does not answer your
questions, or you would like more information, please

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.
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
Is it me, or is the print getting smaller?
For many, middle age is when a lot of things come into
focus, except that is, newspapers, magazines, and computer
screens.
Usually beginning in their 40's, people experience blurred
vision at near points, such as when reading, sewing, or
working at the computer. There's no getting around it, this
happens to everyone at some point in their life. Even if
they never had a vision problem before.
Signs of Presbyopia
When people develop presbyopia, they feel they need to hold
books, newspapers, menus, and other reading materials at
arm's length in order to focus properly. When they perform
near work, they may have headaches or eyestrain, or feel
fatigued.
What Causes Presbyopia
Presbyopia is caused by an age related process in which
there is a slow loss in the flexibility within the lens
inside your eye. These age-related changes occur within the
protiens of the lens, making the lens harder and less
elastic with the years. Age-related changes also take place
in the muscle fibers surrounding the lens.
Presbyopia Treatment
Reading glasses are a very common correction for presbyopia
and can be custom made for each individual through an
optical dispenser, or they can be purchased "ready-made"
from a store like Readerwear. Ready-made readers are less
expensive than custom eyewear, allowing you to own several
pairs for a small amount of money. Pre-made reading glasses
also allow you to stash extra pairs in different rooms of
the house, as well as in the car, the boat, the office, and
so on.
