SmartBuyGlasses’ mission is to bring customers the top brands in eyewear at the best prices. The website provides an interactive service to find the right prescription glasses and contact lenses for you. It does this through cutting edge technology, like its free Prescription Lens Scanner app. This scans the lenses in your glasses to reveal your prescription. It also has a free online tool to measure your Pupillary Distance (PD) to help you get the perfect fit. And there’s a free virtual try-on glasses tool, which lets you see what you look like wearing different frames.
