However, most of the existing virtual glasses can not be automatically adjusted according to the eyeball situation, and manual adjustment is needed, which is relatively easy to have errors. The adjusted image is not quite matched with the human eyeball. After all, the human body feels less accurate and easy to wear. Eye fatigue occurs for a while; at the same time, there are still some problems in the smoothness of the existing virtual glasses.
