Abstract
Systems and methods are disclosed for augmented reality devices with prescription lenses. An example augmented reality device may include a frame and a lens coupled to the frame. The lens may include a prescription lens configured to refract light, the prescription lens having a first index of refraction value, a waveguide encapsulated in the prescription lens, the waveguide having a second index of refraction value, and a first coating layer disposed on a first side of the waveguide, the first coating layer having a third index of refraction value. The third index of refraction value may be less than the first index of refraction value, and the first index of refraction value may be less than the second index of refraction value.
