S30, the feedback information for obtaining the tester, and judge according to the feedback information eyesight shape of the tester
Condition.
In the present embodiment, intelligent terminal includes but not limited to smart mobile phone, tablet computer, and has gesture identification or language
Sound identification function.Original testing scheme is transplanted on intelligent terminal real by the present invention with reference to existing visual chart test method
Existing.
Existing visual chart is designed according to the principle at visual angle, so-called visual angle be exactly by extraneous 2 points of light sent out,
It is formed by angle through intraocular node.Under normal circumstances, human eye can tell the minimum range of point-to-point transmission and be formed by visual angle and be
Minimal visual angle, i.e. one point of visual angle.Visual chart is exactly to be designed as unit of one point of visual angle.
Standard visual acuity chart is according to measurement distance and measures function and is divided near vision test type and distant vision test chart, near vision test type measure away from
From being 25 centimetres, survey is near vision；Distant vision test chart measurement distance is 5 meters, and survey is distant vision.Usual visual chart is positioned over lamp
In case, lamp box brightness is generally not less than 200 candelas/every square metre.Improved, the present invention, which also has, surveys near vision and distant vision
Function.Very similar due to surveying near vision and the method for distant vision, only measurement distance is different, and the present embodiment is only to survey distant vision
It is described further.
In step S10, intelligent terminal obtains intelligent terminal at a distance from tester.When measurement, tester can be first in intelligence
Transmission range in energy terminal, then goes to the position of respective distance, starts to test.In the intelligent terminal that some have distance measurement function
