The Vision fatigue /A Near Sight Treating Device generates photo pulses with fixed frequency as well as electrical pulse with fixed frequency and range to massage and stimulate central nerve system and peripheral nerves in muscles adjusting vision so as to yield the following treatment results: (1) improve the circulation and blood supplies of the local blood vessels, and relax eye muscles to recover the vision fatigue (asthenopia), and then to prevent the development of near sight (myopia); (2) prolonged usage can stimulate vision refractive system to regulate the depth of front room (camera oculi anterior) of eye balls, shorten the eye axle, i.e. improve the refractive errors (ametropia) of near sight, recover light near sight. The advantages of the device are its high portability, low cost, easy to be used, and effective for vision fatigue recovery of computer operators, long distance drivers, especially for the treatment of young students write false near sight (false myopia).
