Ordering Two Pairs: What One Prescription Per Order Means

A useful glasses purchase starts with a specific question. This guide helps you work through second pairs before you choose your next pair.

By the Fast Eyeglasses team · October 25, 2026

Decide who the order is for

Two styles for one wearer are different from two people’s glasses. Fast Eyeglasses uses one prescription per online order. A family should not enter one person’s numbers while adding another person’s frame and expect checkout notes to turn that into two separate prescriptions. Ask the store about separate orders instead.

Check each pair independently

A second frame still needs its own model, color, size and lens selections. Copying the first pair’s style preference does not establish that the second frame fits. Review both lines of the cart and the selected coatings or tints before payment.

Understand the discount target

COUPON20 discounts one lowest-priced eligible complete pair when two or more eligible pairs are ordered together. It includes selected upgrades and excludes prescription-strength charges. It is not a blanket percentage off the whole order and cannot combine with Fast Cash. Read the full terms and final total.

Prepare one clear prescription packet

Use the current genuine prescription and the wearer’s measured PD for the intended use. If the two pairs are intended for different optical tasks, ask before assuming the same information fills both orders. A discount should never determine the measurement or lens powers entered.
