The present invention belongs to the technical field of myopia prevention and control, and specifically relates to a kind of intelligently adjustable defocus glasses, including a glasses frame and glasses legs connected to both ends of the glasses frame by hinges, the lower end surface of the glasses frame is symmetrically provided with two inner lenses and two outer lenses, and the outer lenses are located on the side of the inner lenses away from the glasses legs, the outer lenses are detachably connected to the glasses frame, and the inner lenses can be adjusted along their length direction on the glasses frame; the outer lenses and the inner lenses adopt Alveraz free-form surface design and realize 0~6D adjustable, the inner lenses include a central visual area and a multi-point defocus area surrounding the central visual area, and a plurality of micro-convex lenses are distributed in a multi-circular array in the multi-point defocus area. The shortcomings of the existing defocusing technology are overcome, and the curvature of the defocusing surface is smoothly changed by using the gentle movement of the inner lenses to improve the wearing comfort; through training, the eye axis growth rate can be controlled within 75%, and the eye contrast sensitivity and vision can also be improved.

To provide a subjective optometer capable of efficiently proceeding with subjective measurement of an eye to be examined.SOLUTION: A subjective optometer having subjective measuring means for measuring at least eyesight of an eye to be examined by presenting an examination target to the eye to be examined includes: first corrected eyesight value acquisition means for acquiring a first corrected eyesight value, which is a measurement result of measuring the highest eyesight value of the eye to be examined, in a state that eye refractive power of the eye to be examined is corrected by a predetermined correction degree; reference value setting means for setting a reference value for checking propriety of the correction degree for the eye to be examined on the basis of the first corrected eyesight value; second corrected eyesight value acquisition means for acquiring a second corrected eyesight value, which is a measurement result of measuring the eye to be examined using the subjective measuring means, in a state that the eye refractive power of the eye to be examined is corrected by the predetermined correction degree; and control means for executing predetermined control according to the propriety of the correction degree of the eye to be examined on the basis of whether the second corrected eyesight value of the eye to be examined exceeds the reference value.SELECTED DRAWING: Figure 1

A vision detection method and device, computer readable storage medium and terminal, the method comprising: determining the initial vision value of a user; according to the initial vision value, displaying at least two rounds of test icon groups to the user, and receiving the click instruction of the user on the test icon after each round of display; whenever there is a correct click in the click instruction in two consecutive rounds, displaying at least two rounds of test icon groups corresponding to the increased preset level vision value, and receiving the click instruction of the user on the test icon after each round of display, until there is an incorrect click in the click instruction in two consecutive rounds; when there is an incorrect click in the click instruction in two consecutive rounds, taking the reduced one-level vision value of the vision value corresponding to the test icon as the detection vision value of the user. The present application can enable the user to realize efficient self-service vision detection, and effectively improve the interest, convenience and accuracy of vision detection.
