Abstract: Proposed is a vibration unit available for eyesight recovery glasses, the vibration unit being mounted on any one side or each of left and right eye sides of a frame unit of the eyesight recovery glasses, wherein the vibration unit is configured to generate ultrasonic waves through vibration. Accordingly, ultrasonic waves in a low frequency band are directly transmitted to the eyeball rather than inducing an eye movement, thereby being capable of providing the vibration unit available for the eyesight recovery glasses realizing a substantial eyesight recovery effect. In addition, the ultrasonic waves transmitted to the eyeball may help to relieve eye strain, to increase blood flow, and to activate eye cells.
