Retinal imaging laser eyewear with focus-free and augmented reality

Abstract

Retinal Imaging Laser Eyewear has a miniature laser projector inside the frame which provides the wearer with digital image information through the pupil using the retina as a screen. This compact universal-design eyewear features focus-free and augmented-reality image independent of the wearers' visual acuity and point of focus. This paper describes the background of this technology, the principle of focus-free imaging, the device with a trademark of RETISSA®, and its laser safety analyses based on international guidelines and standards.
