Contact lens questions
Do I need a prescription to order contact lenses?
Yes. Federal law requires a valid, unexpired contact lens prescription. We verify every order with your eye doctor before it ships.
Can I use my eyeglass prescription?
No. A contact lens prescription is different: it includes the brand, base curve, and diameter, and the powers often differ from your glasses because the lens sits directly on your eye. If you only have a glasses prescription, ask your eye doctor for a contact lens prescription.
How does prescription verification work?
After you order, we contact your eye doctor's office to confirm your prescription. Under federal rules, your doctor has eight business hours to respond. Uploading a copy of your prescription with your order usually speeds things up.
My prescription has expired. Can I still order?
We can't fill an expired prescription. You'll need an updated exam from your eye doctor. Heavyglare does not perform eye exams.
Can I switch to a different brand or a cheaper lens?
Only with your eye doctor's approval. Lenses fit and perform differently, so your prescription names a specific lens. If you want to try another brand, ask your doctor to update your prescription.
How fast will my lenses arrive?
Your order ships once your prescription is verified and your lenses are fulfilled. Expedited shipping shortens the delivery time after your order ships; it doesn't speed up verification or fulfillment.
