By automatically adjusting the lens placed in front of users, the legendary Apple smart glasses can make AR / VR users see more clearly, and can also improve the comfort of long-term close viewing. It is reported that some advanced AR / VR systems have introduced adjustable lens mechanisms.

Through the fluid and pressure to quickly adjust the extendable lens to reduce the user’s workload accordingly. < / P > < p > as shown in the figure, the charging pump can pump or pump liquid into the chamber when necessary, and then push out the lens or bend it. By changing the optical characteristics of the mirror group, it can meet the needs of more users. < / P > < p > depending on the arrangement of lenses, various elements can form catadioptric reflection, and the thickness depends on the filling part of the liquid. In addition, by installing multiple actuators around the flexible lens, the shape of the lens can be adjusted more precisely. < p > < p > it is reported that apple is developing some form of AR / VR headgear, and many people speculate that it is the legendary Apple glass smart glasses. The truth remains to be tested. IPhone 12 whole family barrel model exposed: it’s a tribute to iPhone 4
