VR TECHNOLOGY-BASED METHOD FOR OPTOMETRY AND SIMULATION

摘要

A VR technology-based method for optometry and simulation, which comprises the following steps: for the same imaging point of an observed object, defining various possible different field of view directions g in one vector space K, and defining a specific field of view direction g in conventional optometry in another vector space K'; defining a mapping matrix T of the two spaces: K'→K; converting various parameters of the specific field of view direction g into parameters of the K space by means of the mapping matrix, thereby obtaining the optimal imaging parameters of a lens comprising the various different field of view directions; the lens made according to the optimal imaging parameters of the lens may meet actual usage requirements; even if the eyeball of a wearer turns to the field of view direction at an edge of the lens, the imaging effect of the lens is still very good.
