The E-Vent's lens system is a very advanced and optically
correct lens. Although at first glance it looks like a 'flat
lens', it actually changes in thickness to maintain the
best optical quality possible.
Lens is an extremely safe quick release system. It can
be replaced in seconds, but yet is held very securely into
the mask and frame. Unlike other quick release systems,
the E-Vent's lens fits in under the nose piece. This means
the nose area doesn't deflect in when shot, so it prevents
the ingress of paint into the goggle under the lens.
