Description

Technical Field

[0001] This utility model relates to the field of vision training technology, and in particular to a vision training device with a small-volume folded optical path. Background Technology

[0002] The occurrence of myopia is directly related to prolonged close-range use of the eyes. Children and adolescents have strong eye accommodation, but prolonged close-range reading, writing or looking at electronic products will keep the eye muscles in a state of tension. Over time, this will lead to a decline in accommodation and eye muscle spasms, which will eventually develop into myopia.

[0003] Currently available vision training devices on the market are not mature enough, have poor user experience, and low user compliance. Traditional optical path vision training devices are bulky and cumbersome to wear, and the imaging position is still too close, resulting in a poor experience and failing to achieve the desired training effect.

The vision training module, left dark chamber, right dark chamber, flexible FPC, reflective lens, and circuit board are arranged between the middle frame and the rear shell.

[0008] Multiple light source devices are arranged in a spiral on the flexible FPC, and the flexible FPC is wrapped around the outer surface of the vision training module. The vision training module is equipped with light guide plates that correspond one-to-one with the positions of the light source devices. The left dark chamber and the right dark chamber are respectively located on the left and right sides of the vision training module, and reflective lenses are installed on both the left and right dark chambers.

[0009] The flexible FPC, vision training module, reflective lens, left dark chamber, right dark chamber and lens device together constitute the optical path system.
