Fig. 27 Not recommended for baseball or softball. Left of dividing line: The “C Flap” type of protector for baseball and softball batters is not recommended. When impacted from the front (center), there is direct impact of the ball onto the eye. When impacted from 45 degrees, directly onto the C flap, the flap contacts the eye. Both impacts with soft (RIF 1) baseballs at 68 mph. Right of dividing line: Both of these protectors, advertised for youth baseball, fail when tested to ASTM F803 for youth baseball.
