In the testing process, the user is prompted to watch the clearly visible position, and eyeballs of the user are tracked. And judging whether the current focusing position of the eyeball of the user in the diopter test chart corresponds to the position of the normal diopter region according to the eyeball tracking, if so, judging that the current diopter value meets the visual requirement of the user, and entering step S480. If not, it is determined that the current diopter value does not meet the user' S vision requirement, and step S460 is performed.
Step S460, diopter is adjusted for the first time in the determined diopter adjusting direction, and whether the adjusted diopter value meets the visual requirement of the user is judged.
In the determined diopter adjustment direction, for example, the determined diopter adjustment direction is to increase the distance between the second lens and the display screen by a distance step a each time. The adjustment mode may be that the positions of the first lens and the display screen are kept unchanged, the second lens is gradually adjusted by the electric motor to move leftwards, or the positions of the first lens and the second lens are kept unchanged, the display screen is gradually adjusted by the electric motor to move rightwards, the distance between the second lens and the display screen is increased by a distance step a each time, and the distance L2 between the second lens and the display screen is adjusted to be A+a from the distance A corresponding to the current diopter value.
After the diopter is adjusted for the first time, the user is prompted to watch the position which can be seen clearly, and eyeballs of the user are tracked. And judging whether the current focusing position of the eyeball of the user in the diopter test chart corresponds to the position of the normal diopter region according to the eyeball tracking, if so, judging that the current diopter value meets the visual requirement of the user, and entering step S480. If not, the current diopter value is judged to be not in accordance with the vision requirement of the user, and the step S470 is carried out to further carry out diopter adjustment.
And S470, carrying out diopter nth adjustment in the determined diopter adjustment direction, and judging whether the adjusted diopter value meets the visual requirement of the user.
For example, the positions of the first lens and the display screen are kept unchanged, the second lens is adjusted to move leftwards through the electric motor for a plurality of times, the distance between the second lens and the display screen is increased by a distance step a each time, and the distance L2 between the second lens and the display screen is adjusted to be A+n x a from the distance A corresponding to the current diopter value. After each diopter adjustment, the user is prompted to look at a position which can be seen clearly, and eyeballs of the user are tracked. And judging whether the current focusing position of the eyeball of the user in the diopter test chart corresponds to the position of the normal diopter region according to the eyeball tracking until the current diopter value is judged to be in accordance with the visual requirement of the user, and entering step S480.
And step S480, saving the diopter value after the last adjustment as the diopter of the left eye lens corresponding to the user, finishing the diopter adjustment of the left eye lens, and switching to the right eye lens to perform diopter adjustment according to steps S440 to S470.
