Embodiment Construction

[0036] The following is attached Figure 1-2 The application is described in further detail.

[0037] The embodiment of the present application discloses a method for controlling an optometry instrument.

[0038] refer to figure 1 , a control method for optometry, according to the people's eyes in the fatigue state, the sensitivity of the pupils of the eyes to light is increased, so that under the same light intensity, the diameter of the pupils of the eyes in the fatigue state is smaller than that in the normal state between the pupils of the eye. After the subject's eyes are aligned with the optometry body, the main process of the control method of the optometry is described as follows:

[0039] S1: Obtain the first illuminance information. The first illuminance information is the light intensity around the subject. For the light intensity, an illuminance sensor can be installed on the optometry body, and the first illuminance information can be obtained through the illum...

Abstract

The invention relates to a control method of an optometry unit. The method comprises the following steps of: acquiring first image information; presetting a first minimum threshold value, a second minimum threshold value and a maximum threshold value of the diameter of the pupil according to the first image information; acquiring detection information; judging whether the detection information is adjustment information or not; if yes, adjusting a sighting mark and an auxiliary objective lens according to the adjustment information; if not, acquiring second image information, which is the diameter of the pupil of the current eye; judging whether the second image information is larger than the first minimum threshold value of the pupil diameter or not; if not, giving an alarm to remind the detected person of detection after rest; and if so, completing the detection. The method has the effect of improving the accuracy of vision detection.

Description

technical field [0001] The present application relates to the field of vision detection equipment, in particular to a method for controlling a refractometer. Background technique [0002] With the advent of informatization, the use of electronic products has gradually become popular in our lives. While the electronic age brings convenience to our lives, some users frequently use electronic products, and even stay up late to use electronic products such as mobile phones and computers, which causes eye fatigue and vision loss. [0003] At present, the relevant technology discloses a refractometer, which includes a keyboard, a refractometer body and a combined optometry table. Both the keyboard and the refractometer body are installed on the combined optometry table, and the keyboard is electrically connected to the optometry body. Send instructions to the refractometer body through the keyboard, and the refractor automatically switches the visual mark and auxiliary lens accor...
