While your contact lenses and eyeglasses prescriptions may seem the same, they usually have some differences, even if they seem minor.
Contact lens prescriptions have additional parameters for the diameter and curvature of the lenses, which aren’t needed for glasses. However, even the power strength fields (SPH, CYL, AXIS) are often quite different between your own glasses and contacts prescriptions.
We recommend that you get both prescriptions from your doctor if you want to purchase both eyeglasses and contact lenses. They belong to you:
For contact lenses only, the law requires us to contact your doctor’s office to verify your prescription and make sure that it’s valid and accurate.
Warranty type will be determined by the date of contact. All Refunds/Credits will be issued on date of receipt. Returned items must be in original condition in the hard case you received from us. However you may keep any accessories as our free gift.
