Rx: Other Frequently Asked Questions
Can I use discount codes or gift cards on my prescription order?
Discount codes can't be used on prescription orders, and Rx orders aren't included in sitewide sales or promotions. Knockaround gift cards can be used on Rx orders.
Can I get prescription lenses put in Knockaround sunglasses I bought in the past?
We don't add prescription lenses to sunglasses you already own. All prescription glasses must be a new order placed with an up-to-date prescription.
If you'd like prescription lenses in your current Knockarounds, a local optical shop may be able to fit them. Please note that damage to frames or lenses during third-party installation isn't covered by our warranty.
Does Knockaround offer photochromic lenses?
Not at this time.
Can I get bifocal lenses?
No Bi-focal lenses. We currently only offer Progressive and Single Vision lenses.
Can I move my prescription lenses into another Knockaround frame?
We don't recommend it. Prescription lenses are cut to fit one specific frame, and forcing them into another frame, even the same style in a different color, can crack the lenses or the frame. Damage from swapping lenses isn't covered by our warranty. To wear your prescription in a different frame, please place a new Rx order.
Why do prescription lenses cost more than regular sunglasses?
A prescription lens is made to your exact prescription, measurements, and frame. Each pair is crafted and checked before it ships to make sure your vision is crystal clear. We've priced our Rx to stay affordable compared with similar prescription sunglasses.
How often should I update my prescription?
Most prescriptions are valid for 1–2 years. Check the expiration date on yours. If you notice tired eyes or blurry vision, it may be time for an eye exam.
If my prescription changes, can I get new lenses for my frames?
You'll need an updated prescription from your eye doctor and a new Rx order. A changed prescription isn't covered under warranty.
What's the difference between prescription glasses and readers?
Readers use the same magnification in both lenses and are made to fit a wide range of people. Prescription glasses are made for your eyes specifically, including any differences between your eyes, astigmatism, and your pupillary distance (PD), so your vision is as sharp as possible. Because of that, prescription glasses won't work as well for someone else, while readers can be shared.
