You can get prescription lenses for your Spectacles for as little as $29

Snap Inc.'s Spectacles are the latest craze (assuming you can buy a pair). But if you regularly wear glasses, it can be a bit of a challenge to use the Snapchat sunglasses, which aren't available with prescription lenses.

Thankfully, online glasses company GlassesUSA.com is aiming to help that, offering prescription Spectacle lenses starting at $29 for single vision lenses, although that cost can rapidly increase depending on tinting, UV protection, and prescription type. Still, it's potentially a much cheaper option for those looking to upgrade their Spectacles to full-out prescription glasses.

Although Rochester Optical may have beaten GlassesUSA.com to the punch in offering prescription Spectacle lenses, their lenses started at $99 — almost as much as the $129 Spectacles themselves. The company originally required you to ship your Spectacles to its store in Rochester, NY to install the lenses, but now it's offering a self-installation option.

The GlassesUSA.com Spectacles lenses are available now, and ship in 10–12 days with an included tutorial for popping out the old lenses to replace them with your new prescription.
