Light weight ophthalmic lenses include a curved back lens attached to a curved front lens assembly having a functional element. An ophthalmic lens includes a curved front lens assembly and a curved back lens. The curved front lens assembly has an essentially constant thickness, forms an external world-side convex surface of the ophthalmic lens, and includes a functional element operable to modify an image of a real world scene viewed via the ophthalmic lens. The curved back lens forms an external user-side surface of the ophthalmic lens, has a world-side convex surface that is shaped complementary to and interfaced with the front lens assembly, and provides a prescribed vision correction.

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.

The disclosed techniques relate to improving sensor data collection/reporting at an automatic replenishment device (ARD). For example, sensor data associated with the item stored at an ARD may be collected. The ARD can calculate a change in the amount of the item stored by the ARD from the sensor data. If the change is over a reporting threshold, the sensor data (or the amount of change) may be transmitted to a back-end system. Reporting may not occur if additional sensor data (e.g., accelerometer data and/or images captured at the ARD) is not commensurate with a user interaction. If the difference is under the reporting threshold or unlikely due to user interaction, the ARD may refrain from transmitting the sensor data. These techniques conserves power at the ARD, relieves the back-end system from needless processing, and enables more accurate indications of the amount of the item stored by the ARD.
