Traditional eyewear frames are designed to accommodate a wide range of prescriptions. This includes the ability to include strong corrective lenses of significant thickness. However, augmented reality (AR) glasses with integrated displays can be much more constrained in terms of thickness, weight, and mechanical features since they have to accommodate a much larger number of components. As a result, traditional eyewear lens installation methods and features may not be feasible in AR glasses. This disclosure describes an ophthalmic lens edge profile and frame construction that minimizes mass and volume. The lens edge combined with the frame construction that includes an outer frame, an inner frame, and a step bevel, allows for a slim and compact solution that can accommodate prescription lenses.
