Illustratively, the light source 101 is configured to emit light, and at least a portion of the light enters eyes of a user after being guided by the light path in the housing 100, so that the image capturing component 102 can capture image information of the eyes of the user. The image acquisition component 102 is used for acquiring eye image information of a user, and it is to be explained that the image acquisition component 102 is used as a component for shooting eyes, in the prior art, the image acquisition component 102 is mainly used for acquiring dynamic information of eyes during eye treatment, while in order to identify identity information of the user, an iris sensor is additionally adopted for acquiring image information, the two components are generally assembled and used independently, the image acquisition component 102 is multiplexed, the image acquisition component is used for acquiring the dynamic information of eyes under the action of the control system 103 on the basis of the original dynamic information of eyes during eye treatment, the identity information can be acquired through the specific characteristics of eyes under the conditions of unnecessarily high-precision identification of eye characteristics and unnecessarily high-complexity algorithm, for example, the identification of the outer circumference size of the iris of the user is adopted, in practice, the outer circumference size of the iris can be simplified into a circle shape, and compared with an organic individual, the outer circumference size of the iris is fixed relative to a specific age range, so that the image acquisition component can be used for identification of the identity; and because the specific characteristics of the eyes are identified without complex algorithm support, the method has the effect of low delay, and the response period is shorter; the image information comprises first image characteristic information of at least one eye of a user and/or second image characteristic information of both eyes of the user; the first image characteristic information includes iris size information and the second image characteristic information includes a binocular inter-pupil distance of the user.

Referring to fig. 2, since the center point relative distance D of the two lens barrels is a known calibration value when the apparatus is shipped, when the pupil distance is smaller than the center distance of the lens barrels, the deviation distance of the right eye from the center of the right lens barrel is D1, and the deviation distance of the left eye from the center of the left lens barrel is D2, the pupil distance d=d-D1-D2; referring to fig. 3, when the pupil distance is greater than the barrel center distance, the deviation distance of the right eye from the right barrel center is D1, the deviation distance of the left eye from the left barrel center is D2, and the pupil distance d=d+d1+d2.
Illustratively, the light emitted by the laser light source 201 has a first power and a second power that are directed sequentially to the eyes of the user, the first power being less than the second power. After the electronic device is started, the light emitted by the laser light source 201 is a first power light source, at the moment, in order to collect user identity information, the user identity information can be collected before the first power light source emits, the control system 203 receives a trigger signal of the proximity sensor 204, the image collecting component 202 is controlled to collect eye image information of the user, the identity information of the user is determined, at the moment, the user firstly contacts with the light emitted by the laser light source 201, adaptation is carried out in a needed time, the first power with smaller output power is used, the eye safety of the user can be ensured, and meanwhile, the pupil can be guided to reach the pupil size close to the pupil size when the light source irradiates under the second power under the irradiation of the light source with certain power, so that the validity of the eye entering power is ensured; after the identity information of the user is matched, the control system 203 controls the output of the laser light source 201 according to the identity information of the user, at this time, the treatment stage is that the light emitted by the laser light source 201 is of the second power, and the purposes of treating myopia, delaying and controlling the progress of myopia, relieving asthenopia and improving the naked eye vision are achieved by using red light with the wavelength of 630nm-700 nm.
The effect of the scheme provided by the invention is illustrated by measuring the pupil diameters of the test staff, wherein the pupil sizes of the 50 test staff under different illumination intensities are shown in the following table, the reference pupil diameters are set to be 4mm, the first power illumination with the power of 0.03mW and the second power illumination with the power of 0.2mW are respectively in no illumination, and the test data are shown as follows:
From the above table test data, it can be seen that with the first power light irradiation, the pupil diameter at the early stage is closer to that at the treatment stage, and there is a large difference from that in the absence of light irradiation. The average pupil diameter of 50 groups of testers is 5.9mm under no illumination condition, the average pupil diameter of the first power light source under illumination condition is 3.3mm, and the average pupil diameter of the second power light source under illumination condition is 3.0mm. For ease of calculation, assuming the pupil is a standard circle, the average pupil area of 50 groups of test persons is 27.8mm 2 under no illumination, the average pupil area under the first power illumination is 8.8mm 2, and the average pupil area under the second power illumination is 7.2mm 2. If the pupil area under the condition of no illumination, namely the pupil diameter collected before illumination, is used as an input parameter for calculating the emitted light power of the laser light source 201, the actual output light power is only 25.9% of the treatment design power, and the treatment effect is greatly reduced; the first power illumination condition eye image information capturing is increased, namely, the image information of the eyes of the user is acquired under the first power illumination condition and is used as the input parameter of the emitted light power of the laser light source 201, the actual output light power reaches 81.8% of the treatment design power, the treatment effect is close, fine adjustment is performed according to the adjustment strategy in the treatment process, the safety is ensured, the optimal treatment effect is achieved, namely, the power fluctuation adjustment is achieved in the treatment stage, so that the eye-entering light power is matched with the pupil size in the real state, and the optimal treatment effect is achieved in the whole light eye-entering process.
