An organic light emitting diode display and a stereoscopic image display using the OLED display are disclosed. A cover member is pivotally attached to the upper ends of the side arms allowing the arch bar to be collapsed rearwardly if the craft is approaching an overhead obstruction. When the trigger is pressed, the high pressure air drives the cylinder move downwardly to open the head valve for guiding the high pressure air to drive the piston downwardly move to hit nails. Each light-emitting structure includes a base, a conducting element, a light-emitting element and an encapsulation element. The eyewear further includes a head strap attached to the frame and at least one retroreflective element attached to the head strap to be visible by others in low-light conditions.
