Single Vision Standard Lenses
The most common prescription lens. Standard single-vision lenses correct for one focal distance — either near or distance vision. Made from lightweight CR-39 plastic.
Single vision lenses have a single power throughout the entire lens. They're the most commonly prescribed lens type and are used for:
- Distance vision — for people who are nearsighted (myopia)
- Near vision — for reading glasses and farsighted prescriptions (hyperopia)
- Computer distance — mid-range single vision for screen work
Standard CR-39 Material
Standard single vision lenses are made from CR-39 plastic — a lightweight, impact-resistant optical plastic that has been the industry standard for decades. It provides excellent optical clarity at an affordable price.

Who Should Choose Standard Single Vision?
If your prescription is in the mild-to-moderate range and you wear your glasses for either reading or distance (not both), standard single vision lenses are the most cost-effective choice. For stronger prescriptions, consider a higher-index lens to reduce thickness.
