Prescription sunglasses

If your two priorities are realistic virtual try-on and a painless path from frame to prescription sunglasses, I’d focus on these:

My take

Warby Parker is probably the smoothest if you want the process to feel like normal retail: pick a frame, virtually try it on, then select prescription lenses. Its current site specifically supports virtual try-on for sunglasses and offers prescription sunglasses, with UV-blocking prescription lenses and lens coatings included in its eyewear offering.Warby Parker+1

Zenni is particularly good if you care about accurate scaling. Its virtual try-on uses biometric scaling and PD information, and it explicitly supports prescription sunglasses, different tints, polarization and mirrored lenses. Zenni nevertheless recommends checking the actual frame measurements—the virtual preview isn't a guarantee of physical fit.Zenni Optical+1

EyeBuyDirect is a good budget alternative: its virtual try-on is designed to help you assess the frame on your face, after which you simply add your prescription lenses.EyeBuyDirect

A recent 2026 hands-on comparison from NCOA also found all four—Warby Parker, Zenni, EyeBuyDirect and GlassesUSA—to offer virtual try-on, while noting that prescription-sunglasses costs can rise substantially with polarization and other lens upgrades.National Council on Aging

One important caveat: virtual try-on is much better at answering “Do these look good on my face?” than “Will these physically fit perfectly?” For the latter, compare the listed lens width, bridge and temple measurements with a pair you already own.

If you tell me your prescription strength (roughly), budget, and whether you want polarized lenses, I can narrow these down to 2–3 retailers and compare the actual lens-upgrade costs.
