Abstract
A lens for a head mounted display is configured for directing and collimating image light from pixels of an electronic display to a pupil of a user's eye to lessen a pupil swim effect. A method of configuring a lens for directing and collimating image light from an electronic display to a pupil of a user's eye includes configuring the lens to lessen a difference between observed distortions of imagery displayed by the electronic display at different gaze angles of the user's eye.
