Ordering Prescription Prism Glasses Online

Prism correction is part of a prescription, not a lens feature that should be added without one. If your prescription includes prism, Olet lets you enter both vertical and horizontal prism values, along with the required base directions, directly in the online ordering process.

Prism Correction Made to Your Prescription

Prescription prism glasses use prism values measured in prism diopters (Δ), together with a base direction such as Base In, Base Out, Base Up, or Base Down. Your prescription may contain prism for one eye or both eyes, and may include vertical, horizontal, or combined prism values.

Enter these details exactly as they appear on your prescription. If anything is unclear, upload the prescription instead of estimating the values. Prism should only be added when it has been prescribed by your eye-care professional.

What Do Prism Glasses Look Like?

Most prescription prism glasses look much like regular prescription eyeglasses because the prism correction is built into the lenses. The finished lens thickness and appearance can vary depending on the amount of prism, your other prescription values, frame size, and lens material.

Prism may be prescribed in some cases involving double vision or binocular vision alignment, but whether prism is appropriate—and the amount and base direction required—should be determined by your eye-care professional.
