Abstract
The apparatus comprises: an adjustable lens module, configured to image an object viewed by eyes an eye; an analysis and processing module, configured to determine whether time during which a change amount of a distance between a gaze point of the eye and the eye is within a set range exceeds a set threshold, and when the time exceeds the set threshold, send adjustment triggering information to a parameter generating module; the parameter generating module, configured to generate adjustment information of an imaging parameter of the adjustable lens module according to the adjustment triggering information; and a lens adjustment module, configured to adjust the imaging parameter of the adjustable lens module according to the adjustment information of the imaging parameter. A probability of occurrence or deterioration of a sight problem, e.g., nearsightedness, due to improper use of eyes is reduced without affecting work, study, entertainment, etc. being currently performed by a user.
