Single Vision

Single vision is the most common type of prescription lens. This lens type features a single field of vision, or one prescription power throughout the entire lens, for correcting nearsightedness (myopia) or farsightedness (hyperopia).

Single-vision lenses are also used for reading glasses. Reading glasses may either be prescription or over-the-counter. Over-the-counter reading glasses are the same power in both eyes, and often use powers such as +1.00, +1.50, +2.00, or +2.50 (or quarter steps in between). Prescription reading glasses are tailored to you, and may require some math to order.
