Embodiment Construction

[0018] Normal vision of adolescents is increasingly becoming a scarce resource. In the evaluation of entering higher education, vision is recorded as 10%. Students have 600 points for cultural classes and 60 points for vision. Therefore, students attach great importance to vision, and the school attaches great importance to vision. Every semester is at least common throughout the school. The visual acuity is tested once, and each person must be converted into visual acuity scores each time, which is used as the basis for school performance assessment and student performance assessment. This test is done by an independent health department. The calculation of the visual acuity measurement value can be written as a formula

[0019] z=c-ax-by-d-e (1)

[0020] In formula (1), z is the total visual acuity score value, c is the base value of the score when the visual acuity is normal, a is the coefficient of the visual acuity change x value during the semester, b is the coefficient of t...

Abstract

The invention discloses an assessment method for entering high school and the visual acuity test device combining with the test of vision, fundamentally solving the problem that the existing visual acuity test method can not fast and correctly reflect the actual condition of the vision, and is favorable for fast and correctly measuring the vision in bulk, to make it possible that the correct vision level is combined as one part of the grade for entering high school.

Description

Technical field [0001] The present invention relates to a method for restraining the trend of vision decline, a method of visual acuity detection by the user himself, and a visual acuity measuring device. Specifically, by including a certain percentage of visual acuity scores in the college entrance examination results, sufficient attention has been paid to myopia prevention; To this end, multiple methods and devices for quickly and objectively measuring eyesight are required, through the rotation of the eye chart and the positioning of the chin to achieve objectivity, and the single board computer automatically generates test items to achieve rapid testing. Background technique [0002] In recent years, due to the popularization of televisions and computers, coupled with the partiality of the evaluation method of learning, the rate of myopia among young people has been increasing. For this reason, it is necessary to draw attention to the evaluation of vision in the evaluation of...
