6over6 is the developer of GlassesOn, a digital healthcare platform that enables users to perform their own vision test. Its simple-to-use apps are designed to enable a complete and accurate measurement of the refractive error of the eye for prescriptions for eyeglasses or contact lenses. The company's apps are clinically proven to be as accurate as an optometrist's exam.

Using only a smartphone, users can accurately measure the refractive error of their eyes through the manipulation of light. GlassesOn users can get a complete prescription for farsighted or nearsighted vision, pupillary distance, and astigmatism.

GlassesOn is registered as a Class 1 Exempt Medical Device on the US FDA's Medical Device Listings. However, it does not provide medical advice and does not replace a full eye health exam.
