The invention relates to the technical field of myopia prevention and control, in particular to a phototherapy device for myopia prevention and control, which comprises a shell, a
light source and a light path module are arranged in the shell, and light emitted by the
light source passes through the light path module and then is emitted to the macular position of eyeballs of a patient is weakened. Light emitted by the
light source is projected to the
retina through the light path module,
blood flow and
blood supply are increased after the
choroid below the
retina is irradiated by the
red light with proper intensity, the original atrophic
choroid and
retina are restored,
sclera hypoxia is fully supplemented, and therefore myopia is effectively prevented and controlled. Meanwhile, as
choroid distribution at the macular position is denser than that of other parts and is more sensitive to light, the light path module is designed in a targeted manner, and energy of light emitted to the macular of the eyeball of the patient is weakened through different
modes such as shielding, scattering, reflection and distribution of
light guide points, so that the
treatment effect of the macular macular is improved. Damage and
calcification to macules in the process of using the phototherapy device for myopia prevention and control for a long time are avoided.
