How can I differentiate reading glasses from prescription glasses?

Reading glasses are designed to address presbyopia. This condition is caused by reduced lens elasticity, mostly found in people aged 40 and above. They cannot see objects from a close range, hence requiring reading glasses to magnify the writing for easier reading. On the other hand, prescription glasses are designed to correct vision in line with a person's specific vision problem. These glasses must be prescribed by an eye doctor and cannot be purchased over-the-counter like reading glasses.
