Since Crystal Blue Pro includes built-in reading magnification in the lower lens zone, wearing them over prescription contact lenses may cause conflicting corrections. If you already wear contacts for distance vision, consult your optometrist before using these glasses.

Shipping typically takes 7 - 14 business days. With fast processing and tracking included, you’ll receive your Crystal Blue Pro quickly and reliably.

We offer a 30-day money-back guarantee. If Crystal Blue Pro isn’t the right solution for you, you can return it hassle-free for a refund.
