Reading Glasses

When you reach the point of not being able to
read up close without stretching your arms to the limit, you may need to consider single-vision reading glasses. Reading glasses come in two main styles:
full frames, in which the entire lens is made in the reading prescription, and half-eyes, the smaller
"Ben Franklin" style glasses that sit lower down on the nose.
Full reading glasses are suitable for people who spend a great deal of time concentrating on
material close-up. If you try to look up and across the room through the reading lenses, everything appears blurry.
In contrast, half-eye reading glasses allow you to look down and through the lenses for near work, and up
and over them to see in the distance. Generally, people who have never needed glasses in the past will start out with a pair of reading glasses rather than
bifocals
or no-line progressive lenses
(which are usually a better choice if you have a need for distance as well as near correction).
Handy accessories for temporary use, such as an evening in a dimly lit restaurant,
include tiny foldable readers that fit in pen-sized cases and magnifiers that hang
around your neck like a pendant. You may have even seen plastic lenses mounted in credit card-sized holders that slip easily in
a wallet horrible for reading a book, but fine for those moments of desperation when you just want to know
if the menu says "filet de boeuf" or "foie gras."
Also available are tinted reading glasses with UV protection for wearing outdoors in
the sun; a popular type is the sunglass bifocal, with a nonprescription upper half for looking far away and a reading prescription in
the lower half for close up.
Why Custom-Made Reading Glasses Are Usually Better Than Pre-Fabricated Ones
Reading glasses can be custom-made for each individual through an optical dispenser, or they can be purchased "ready-made" at a pharmacy or department store. Ready-made readers became popular in the 1990s: three times
more pairs were purchased during that decade than ever before, at an estimated rate of 30 million pairs per year. They are
less expensive than custom eyewear, allowing you to own several pairs for a small amount of money.

Ready-made reading glasses are available in lots of fun styles and colors, too, so you can experiment with fashion,
purchasing a somewhat outrageous pair of glasses without risking a lot of money. If you don't like the style, you can
always get another inexpensive pair with a more conservative look. Pre-made reading glasses also allow you to stash
extra pairs in different rooms of the house, as well as in your car, office, briefcase, purse, boat, and so on.
One drawback to purchasing ready-made ("drugstore") reading glasses is that they are essentially "one-size-fits-all" items.
The prescription is the same in both lenses, and the location of the optical center of the lenses is not customized for each wearer.
Most people do not have exactly the same prescription in both eyes, and almost everyone has at least a small
amount of astigmatism correction
in their prescriptions. Headaches, eyestrain, and even nausea can result from wearing reading glasses that are too far off
from your actual prescription or that have optical centers too far away from the center of your pupils. If you experience these
problems, visit your eye doctor for a customized reading glasses prescription.
