Abstract: Provided is a device for massaging eyes comprising a mask received in a compartment and comprising annular left and right guards surrounding rear portions of left and right eye portions respectively, and left and right diaphragms in the eye portions respectively; a pneumatic-powered cylinder assembly for converting rotating motion into reciprocating motion; and a plastic tube interconnected the mask and the cylinder assembly. In operation, air having positive or negative pressure is built in the cylinder alternately prior to communicating to the eyes for massaging. There are provided protrusions around a rear portion of each guard. In another embodiment, there are provided left and right soft spacers attached to rear surfaces of the diaphragms respectively.

Abstract: A vision correcting device comprises an eye shield, an air tube fastened at one end thereof with the eye shield, and a pressure apparatus fastened with another end of the air tube. The pressure apparatus comprises a motor, a speed-changing mechanism driven by the motor, an eccentric wheel actuated by the speed-changing mechanism, a roller, a push rod, and an air sac. When the eccentric wheel is actuated to turn clockwise, the push rod is actuated to cause the air sac to contract rapidly and relax slowly so as to bring about a positive pressure in the shield for the treatment of myopia. When the eccentric wheel is actuated to turn counterclockwise, the push rod is actuated to cause the air sac to contract slowly and relax rapidly so as to bring about a negative pressure in the shield for the treatment of hyperopia.
