Shipping & Delivery

Orders are processed within 24–48 hours. Once your order ships you'll receive a tracking number by email. Delivery times and costs are calculated at checkout based on your location.

6 months Warranty

All ReFramed lenses are covered by a 6-month warranty against manufacturing defects. If anything is wrong with your lenses, contact us and we will make it right.

How to Install

Replacing your lenses takes just a few minutes: gently push the old lenses out from the inside of the frame, then snap the new ones in starting from the nose side. Step-by-step guides for your specific model are available on our blog.

Bring your Costa Bayside back to life with precision-cut replacement lenses that snap into the original frame. Polarized to kill surface glare, rated 100% UVA/UVB, and cut from impact-resistant polycarbonate — the performance the frame shipped with, at a fraction of the brand price.

Compatibility

Cut specifically for the Costa Bayside frame. Confirm your model by reading the name stamped inside the temple (the arm over your ear) before you buy.

Lens options

  • Stealth Black — polarized tint with full UV protection
  • Tidal Blue MirrorShield® — polarized tint with full UV protection
  • Titanium MirrorShield® — polarized tint with full UV protection
  • Adapt Gray Photochromic — darkens in bright sun and lightens in shade — one lens for changing light

All lenses are UV400 rated (100% UVA/UVB), polarized to cut glare, and made from lightweight impact-resistant polycarbonate that outlasts glass or acrylic. Covered by a 2-year warranty.

No tools needed — each lens snaps into the original Costa Bayside frame in seconds.

FAQ

Are the lenses polarized? Yes. Every tint listed here is polarized and blocks 100% UVA/UVB.

How do these compare to buying from Costa? Same core performance — polarized, UV400, impact-resistant — at a fraction of the brand's replacement price. ReFramed isn't affiliated with Costa.
