Single Vision Glasses - Prescription Eyeglasses with Single Vision Lenses

Single vision glasses have lenses with a single prescription power, which can correct for nearsightedness, farsightedness, or astigmatism.

Lens materials for single vision glasses include plastic, polycarbonate, and high-index lenses.

If you only need glasses for one type of vision, your optometrist may prescribe single-vision glasses to you. People under 40 usually have this type of lens as they’re more likely to have just one type of visual requirement.
If you’re over 40, you may need to have separate glasses for separate things, such as one pair for seeing far away, like when you’re driving, and one pair for close-up tasks, like reading.
