In another embodiment the front attachment is a gasket that extends for the entire width of the shield and seals against liquid entering between the shield and the helmet. The face shield can have a varying thickness profile to correct for optical aberrations, the thickness profile taken from a center toward one lateral end that has a first region that sinusoidally decreases, and then an adjacent second region that sinusoidally increases to a third region adjacent the second region that sinusoidally decreases.
