Optometer for comprehensively detecting diopter and visual function of eyes and optometry method

Abstract

The invention relates to an optometer for comprehensively detecting diopter and visual function of eyes. The optometer comprises an optometry lifting table, a seat, a computer optometer, a control panel, a function control button, a function execution mechanism and a sighting target assembly, and is characterized in that the sighting target assembly comprises a front sighting target plate and a rear sighting target plate which are provided with sighting target windows, as well as a sighting target card with sighting targets, wherein, the front sighting target plate and the rear sighting target plate are suspended on a near sight test rod; and at least one group of the sighting targets among all the sighting targets are single sighting targets. The optometer further comprises an adjustment sensitivity checking device. The optometry method using the optometer mainly comprises the following steps: (1) diopter detection; and (2) visual function detection. The sighting targets in the structure are changed into single sighting targets so as to improve the judgment accuracy; and meanwhile results can be accurately and effectively checked by the added adjustment sensitivity checking device in a non-hand-held manner. Therefore, by adopting the optometry method, the diopter and the internal visual functional status of eyes can be more comprehensively checked so that the visual health state of eyes can be assessed comprehensively and a reasonable solution can be made further.

Description

technical field [0001] In particular, the invention relates to a refractometer and a refraction method for comprehensively detecting the diopter and visual function of eyes. Background technique [0002] The existing optometry method is mainly to check the diopter of the eyes, only from the diopter can not find the internal visual function problems well, and it is often these factors that lead to symptoms such as deepening of the diopter, visual fatigue, discomfort wearing glasses, etc., the traditional diopter There are many detection methods, but there is a certain error in the accuracy, and the error often occurs because the optometry method is too simple. [0003] Currently on the market, there are many optometry equipment disclosed, such as comprehensive optometry, automatic optometry, etc., and the above optometry cooperates with advanced computer control programs. The standard group is often composed of multiple optotypes. For example, in the vision test we usually d...

[0002] The existing optometry method is mainly to check the diopter of the eyes, only from the diopter can not find the internal visual function problems well, and it is often these factors that lead to symptoms such as deepening of the diopter, visual fatigue, discomfort wearing glasses, etc., the traditional diopter There are many detection methods, but there are certain errors in the accuracy. The error often occurs because the optometry method is too simple.

[0003] Currently on the market, there are many optometry equipment disclosed, such as comprehensive optometry, automatic optometry, etc., and the above optometry cooperates with advanced computer control programs. The standard group is often composed of multiple optotypes. For example, in the vision test we usually do during physical examination, each line of it consists of several optotypes. When these optotypes are tested, customers often see double images. This can easily affect the customer's judgment

[0004] The flip shot used to check and adjust the sensitivity, none of the existing refractometers are equipped with supporting devices, and most of them use manual flip to complete the detection of the check and adjust sensitivity. The flip shot needs to be operated by hand, so there is poor stability. When it is turned over, it is easy to cause defects such as inaccurate lens position, which will affect the inspection results
