Yes — almost every frame in our sunglasses collection can be made prescription. Choose your frame, upload your Rx at checkout, and we'll make single-vision, bifocal, or progressive lenses. Prescription sunglasses typically ship in 7–10 business days.

UV400 blocks harmful ultraviolet radiation (UVA + UVB) that damages your eyes over time. Polarization is a separate lens treatment that reduces horizontal glare — think: sun bouncing off a wet road or lake surface. You want UV400 always; polarized is a preference (great for drivers and anyone near water).

Round faces look best in angular frames (square, rectangle). Square faces suit softer shapes (round, oval, cat-eye). Oval faces work with almost anything. Heart-shaped faces balance with bottom-heavy frames (aviator). See our full face shape guide for measurement tips.

If you drive daily, spend time on water, or are light-sensitive: yes, polarized is worth the $10–15 upgrade. If you're mostly in the city and not light-sensitive, standard UV400 tinted lenses do the protection job at a lower price.
