S110, adjusting the brightness of the display screen according to ambient light;
in the embodiment, the screen brightness of the display is adjusted according to the incidence rate of the light source around the test environment to adapt to the vision test environment; because different environment light shines, the chart detects the peripheral incident illumination rate difference, can cause certain influence to the vision testing result, through adjusting all ring edge borders optics incidence rate in this embodiment in order to adapt to the test environment that vision detected, confirms that the user predetermines test distance simultaneously, and when the user that awaits measuring removes the settlement distance, the interface display stops the suggestion.
S120, determining a user selection result by user-triggered operation under the state of sequentially displaying vision detection symbols of different levels;
in the embodiment, the grade of the vision detection symbol to be displayed is determined according to the test distance, for example, E appears in normal vision detection, the display unit sequentially displays different opening directions E from large to small, the vision detection symbols sequentially decrease, and a user triggers a designated direction button of a display screen to determine a selection result;

In this embodiment, a preset test distance is determined, wherein the viewing angle is an included angle formed by light rays emitted from two external points passing through an intraocular junction (i.e., an angle formed by two points of an external object when the two points are incident into an eye and intersect with each other). Normally, the human eye can distinguish the minimum distance between two points to form the minimum viewing angle, i.e. a sub-viewing angle.
The newly-increased distance sensor of intelligence wrist-watch, eyes and intelligent wrist-watch keep at same water flat line, and when outwards moving certain distance, the suggestion stops appearing in the interface. The brightness of the intelligent watch is automatically adjusted to a proper value, and then different opening directions E are displayed from large to small.
The viewing angle calculation formula is as follows:
h is the picture height;
d is the sight distance;
θ is the viewing angle.
The unit directly obtained by the formula calculation is pi, and when the self-conversion degree is recalculated, the unit required to be input in the formula is CM.
According to the 5-point visual acuity chart calculation rule, as shown in fig. 2, the standard E visual acuity side length is scaled to D/5L (L is the visual acuity side length) according to the visual acuity D to obtain a set of standard E characters suitable for being displayed on a watch, and the visual acuity value of the child is calculated according to the measured minimum recognizable E character.
The algorithm for automatically adjusting the brightness of the mobile phone comprises the following three steps:
s001 establishing curve
Establishing a brightness (unit Lux) curve corresponding to illuminance (the illuminance is luminous flux irradiated on a unit area from a light source and is expressed by E, and the unit of the illuminance is Lux (lx for short)), so that the corresponding brightness value on the smart watch can be calculated according to the illuminance value transmitted by light sensation.
S002 sampling debounce
Collecting the illumination value in a period of time, and then calculating the illumination value in the period of time according to the illumination value in the period of time. The dither elimination is required in consideration of the dither (for example, in the case where the dither changes abruptly and then recovers, or in the case where the dither changes periodically, such as brightness and darkness).
The amplitude limiting average filtering method is adopted, the new data sampled each time is firstly subjected to amplitude limiting processing and then sent into the queue for recursive average filtering processing, so that the reasonability and the smoothness of the data are ensured, and the pulse interference deviation caused by pulse interference can be eliminated for the sporadic pulse interference.
S003 calculate luminance
Finally, the finally adjusted mobile phone brightness is obtained according to the following algorithm
Wherein the content of the first and second substances,
b is the brightness of the environment, and B is the brightness of the environment,
and L is the brightness of the screen of the mobile phone.
