A review of adjustable lenses for head mounted displays

Adjustable lens technology has the potential to improve Head Mounted Displays (HMDs) through style and comfort by providing optical prescription correction and focussing mechanisms integrated within the HMD. It can also reduce simulator sickness and user experience of 3D through resolution of Vergence Accommodation Conflict, and age-related user problems (presbyopia). We review the available technology and the design constraints to show how a fluid filled lens may be appropriate for AR and MR, and an Alvarez lens may be appropriate for VR.
