S2: and determining a maximum threshold value and a minimum threshold value of the brightness according to the first illumination information. The maximum threshold value of the light brightness is the sum of the first illumination information and an allowed deviation value; the minimum threshold value of the light brightness is the first illumination information minus an allowable deviation value.

If the second illuminance information is not between the maximum threshold and the minimum threshold of the brightness, step S12 is performed, otherwise step S13 is performed.
And S12, sending an alarm to remind the detector to adjust the brightness. The optometry instrument body gives an alarm to remind a detector to adjust the brightness around the detected person. After the examiner adjusts the brightness around the examinee, the operation returns to step S10 to obtain the second illuminance information again, and if the obtained second illuminance information is not between the maximum threshold and the minimum threshold of the brightness, the optometry apparatus continues to give an alarm until the brightness around the examinee is between the maximum threshold and the minimum threshold.

And S14, judging whether the second image information is larger than the first minimum threshold of the pupil diameter, if so, executing the step S15, otherwise, executing the step S16.
And S15, finishing the detection. When the second image information is larger than the first minimum threshold value of the pupil diameter, the eyes do not enter a fatigue state, the detection result is accurate, and the optometry apparatus body judges that the detection is finished.
And S16, sending an alarm to remind the tested person to test after rest. When the second image information is smaller than the first minimum threshold value of the pupil diameter, the eyes enter a fatigue state, and the optometry instrument body gives an alarm to remind a detector to arrange the detected person to detect after rest.
