Apple's AR glasses may come with adjustable lenses to deliver image correction similar to prescription lenses
Apple may be working on adjustable lenses to use in its Apple Glass AR device. A patent granted to Apple explains that the company is researching the use of stacks of liquid crystal and non-liquid crystal lenses inside its upcoming AR/VR devices. The physical properties of the liquid crystal lenses could be altered using multiple electrodes to adjust how light interacts with the lenses. For instance, by applying an appropriate amount of electricity to specific electrodes, the lenses could be altered to correct near/far-sighted vision, among other visual defects.
More interestingly, Apple posits that the method can be used to fine-tune the level of adjustment to "reduce disorienting visual sensations caused by changes in magnification." According to the patent application, the eye-tracking system built into the device would, in theory, determine where the user is trying to focus and adjust the area of the lens that is in user's direct line of sight.
Patents don’t always end up in products soon after they are granted. So, don’t take this information as any sort of confirmation that Cupertino will outfit the Apple Glass with such lenses.
