Why can I buy reading glasses without a prescription?

[Colton]

I thought it still needs the prescription as the regular glasses do, but there is no need.Why?

[Bentley]

It is impossible for reading glasses without prescription. reading glasses are some what magnifying glasses specially made for who spend a great deal of time and have problem concentrating on material close-up. Most reading eyeglasses are made to a particular prescription,according to degree of myopia or hyperopia combined with astigmatism.

Reading glasses over-the-counter can help those people who have slightly hyperopia and presbyopia focus on near objects. So if your prescription is not strong, you can get reading glasses without a prescription over-the-counter.
