Reading glasses with a prescription power of +2.5 diopters provide greater support
for near vision. They may be appropriate if books,
labels, or text on a smartphone can no longer be read comfortably with weaker
reading glasses.
Whether +2.5 is right for you depends not only on your age, but also
on your individual visual acuity, your usual reading distance, and
the specific activity you’re doing. The key is that you can read clearly and comfortably at the desired
distance.
What are +2.5 reading glasses used for?
Reading glasses with a prescription of +2.5 diopters help with near-
e tasks. These include, for example, reading
books, menus, labels, craft instructions, or
text on a smartphone.
Compared to +2.0, +2.5 provides stronger support, and
may be suitable for shorter reading distances. For activities
at greater distances—such as working on a screen that is farther away
—a lower power may be more comfortable.
Important to Know
Ready-made reading glasses have the same power in both lenses. If your
eyes have different powers, you cannot see clearly at a distance
, or you have other vision problems, a pair of glasses customized
may be a good option.
