Human eye health state judging system and method

Abstract

The invention relates to a human eye health state judging system. A graphic processing calculation module is utilized to calculate the diameter of the iris in a far point face image and the diameter of the iris in a near point face image, then calculate a sight distance of the single eye at the far point according to the diameter of the iris that the far point face image corresponds to and calculate a sight distance of the single eye at the near point according to the diameter of the iris that the near point face image corresponds to, and then calculate the diopter at the far point and the diopter at the near point according to the two sight distances. The difference between the two diopter values is the adjustment amplitude, and finally the eye health state of a consumer is judged according to the difference between the adjustment amplitude and the empirical value. According to the system, the presbyopia diopter can be measured by a user or an optical store, the influence of subjective factors of consumers in the traditional glasses preparation process is avoided, and the glasses preparation process is simplified. Each consumer can grasp the degree change clearly, so that the consumers can perform eye exercises according to suggestions in diet and life provided by software.

Description

technical field [0001] The invention belongs to the technical field of monitoring the health status of human eyes at a certain moment, in particular to a system and method for judging the health status of human eyes. Background technique [0002] The eye is the visual organ of the human body. External objects are imaged on the retina, and then through the adjustment of the cerebral cortex and the influence of life experience, people can clearly see external objects, and the lens in the eye structure itself is elastic. At the same time, the lens has a certain adjustment ability, which can make people adapt to the distant and near view. When people are young, the adjustment ability of the eyes is strong. With the increase of age, the adjustment ability will gradually decline, and when people use their eyes due to long-term fatigue, irreversible lesions will appear, such as: myopia, hyperopia, etc. At this time There will be lesions that are blurred and cannot be seen clearly,...

AI Technical Summary

Problems solved by technology

[0010] In actual use, it is found that: 1. Both the first method and the second method require complete correction of refractive error, that is, suitable lenses need to be worn, which means that firstly, special equipment such as a refractometer needs to be used for refraction, and then Experienced optometrists carry out the deployment of lenses, otherwise the step of completely correcting the refractive error cannot be achieved

The above-mentioned refractometer is expensive, cannot be popularized, and is not portable. It can only be used in hospitals and is highly professional. Ordinary users cannot regularly test glasses

2. After the first method and the second method have completely corrected the refractive error, they still need to use an eye chart, and the follow-up steps can only be completed under the guidance of a doctor. cumbersome questions

3. The second method and the third method are only suitable for the average value with a large population base, that is, they cannot represent the eye health status of people with different living habits and different working environments.

4. No matter which one of the four methods is used, there are defects that it is impossible to repeat the test multiple times in a short period of time, and to test repeatedly at multiple locations

[0011] To sum up, the existing four methods have different or the same defects, which make it impossible for people to fully measure and record the changes in the adjustment range of the eyes, and it is impossible for people to know the degree of eye fatigue in a period of time at any time. Or the degree of aging, it is not conducive to adopting correct health care methods to recover from eye fatigue, nor can it guide people how to use eyes normally and healthily anytime and anywhere
