Description

Technical Field

[0001] The present invention relates to the technical field of red light amblyopia treatment instruments, and particularly relates to a red light amblyopia treatment instrument with an optometric flipper function. Background Art

[0002] A red light amblyopia treatment instrument is an amblyopia treatment device that stimulates the fovea centralis with red light of a specific wavelength. It uses a red light wavelength of 640nm - 660nm, a transmittance of not less than 65%, and a flicker frequency of 150 times / min. It is mainly applicable to the amblyopia rehabilitation treatment of children over 3 years old. This instrument adopts a glasses-type design, and its red light wavelength range (640nm - 660nm) matches the sensitive characteristics of cone cells. By high-frequency flickering, it inhibits the eccentric fixation points and promotes the restoration of normal visual function.

[0003] By stimulating the cone cells in the fovea centralis with red light flickering, and taking advantage of their high sensitivity to red light, it inhibits the eccentric fixation points of amblyopia patients and reshapes the normal visual pathway. Since rod cells are not sensitive to red light, they can avoid interfering with the treatment process.

[0004] However, it still has the following disadvantages: The functions of the red light amblyopia treatment instrument are monotonous, and the lack of core functions is mainly reflected in aspects such as accommodation ability training, binocular vision function integration, and dynamic visual stimulation.
