Separate prescription from dispensing
Ordering glasses involves both lens powers and placing the lenses correctly in a suitable frame. The College of Optometrists highlights measurement and fit concerns in online purchases, especially for progressives. Its cited research is older and does not score every present-day seller.
Before entering your details
Our order checklist asks whether the prescription is current, whether every sign and axis has been copied correctly, and who will obtain the required measurements. Ask the seller to explain unclear fields. Do not fill an unknown value with an average simply to complete checkout.
Ask who handles adjustments
Find out how the frame will be fitted after delivery, how a suspected prescription or measurement problem is assessed, and who pays for any remake or shipping. Keep the exact lens specification and service terms in writing before ordering.
Check the delivered pair
Use familiar everyday tasks to describe the result: a distant sign, your screen and your usual reading material. If something remains wrong, contact the supplier with a specific account and arrange an appropriate eye-care review. A low price does not resolve an unresolved fitting problem.
