Introduction In humans, prolonged contraction of the ciliary and medial rectus muscles during close reading will result in eye strain. On the other hand, eye strain will not occur if the ciliary and medial rectus muscles do not contract during close reading. About 2cm in front of the eye, the Near-Eye Display (NED)[1] technology of Augmented Reality smart glasses (AR glasses) projects computer generated images/informations(CGIs) directly onto the retina, and this provides a passive way for our eyes to acquire information. Figure 1. Projection of CGI onto the retina Factors contributing to eyestrain and myopia In the medical community, the main factors considered to causing eye fatigue and myopia are as follows: 1. Long-term contraction of the ciliary muscle. 2. Long-term contraction of the medial rectus muscle. 3. Insufficient exposure of the retina to sunlight.[2] 4. The eye not exhibiting peripheral myopia.[3] 5. Peripheral visual field deprivation.[4] Disease prevention "Evidence is mounting that myopia is growing around the world, with a recent study estimating that on average, 30% of the world is currently myopic and by 2050, almost 50% will be myopic, that’s a staggering 5 billion people." https://myopiainstitute.org/myopia/ Augmented reality smart glasses have the potential to play an important role in the prevention of asthenopia and myopia. Termination of asthenopia When using AR glasses, its translucent display allows your eyes to receive two light sources at the same time, one is ambient light from the real world, and the other is projected by the NED. When the display becomes opaque, light from the real world will not penetrate, and your eye will only receive the light from the NED. Similar in principle to an ophth...
