Description
Technical Field
The invention relates to an eye care system and a training method for visual training.
Background
Some studies have demonstrated that myopic patients have more lag in accommodation for the myopic eye than non-myopic patients, and insufficient accommodation of the lens can lead to deviation of the conjugate focus of the retina when looking at near objects for a long time, resulting in different degrees of hyperopic defocus on the retina. The hyperopic defocus enables compensatory eyeball growth of teenager eyeballs in a development period, and causes myopia to occur and develop. Myopic patients have reduced sensitivity to blurred images, inaccurate adjustment, and more prone to lag adjustment.
In farming and animal husbandry and field environments, people frequently switch and adjust their eyes to view distant objects while they are active, and the eye adjustments are relatively in place, such as when hunting or protecting against dangerous animal attacks, where the eyes will adjust very precisely. However, most of the time is indoors, people do near vision activities for a long time, and especially when people watch electronic products, eyes rotate inwards, the refractive power of crystalline lenses is large, muscles are in a continuous tension state, and eye fatigue is caused. The probability that the teenagers need to carefully identify the remote details in learning and life is low, the ability of identifying the remote details is reduced, and the myopia rate is high.
To improve the accommodative ability of the eye, there are many visual training methods. For example, CN101695463B discloses a spectacle frame with vision training function, which comprises a spectacle frame, a nose bridge, a pile head and spectacle legs, wherein the spectacle frame, the nose bridge and the spectacle legs are all provided with a light emitter, one of the spectacle legs is provided with an adjusting switch, and the other spectacle leg is provided with a chamber for placing a battery and a charging hole; the nose bridge or the glasses legs are provided with chips for controlling the luminous bodies to flash or extinguish in sequence according to a program; the luminous body, the chip, the battery and the regulating switch are connected through a flexible circuit board; the angle between the glasses frame and the glasses legs can be adjusted at will by 180 degrees, and when the angle between the glasses frame and the glasses legs is 180 degrees, the light emitters on the glasses legs and the nose bridge are positioned on the same straight line. The spectacle frame with the visual training function takes the movement vision as the theoretical basis, and exercises the eye muscles, protects the eye regulation and effectively prevents and controls the occurrence and the development of myopia through the training of the eyeball movement.
However, as the age is short, the self-control force is poor, many people cannot complete the visual training seriously, and the existing method cannot detect whether the eyes are adjusted in place; in some vision training, for example, the revolving horse lamp is used as the sighting mark to rotate according to a certain track, so that the eyes of the trainee are guided to rotate or do infinity and other motions, and the details in the distance do not need to be seen clearly. Teenagers lack interest in this mechanical, repetitive, lack of interactive training, affecting the training results.
