ESS developed the Crossblade Spectacle to offer a more form fitting frame style with thinner ear pieces which fit under over-the-ear hearing protection.
There are clear and smoke grey lenses and the NARO lens and nosepiece sizes fit narrower faces which helps mitigate fogging experienced when too large lenses are worn. The lenses and nose pieces are interchangeable for a more custom fit.
The lenses feature ClearZone Dual Flow coating to eliminate fog inside and prevent scratches outside. They also conform to Federal OSHA, ANSI Z87.1-2015, CE EN 166 and U.S. MIL-PRF-32432A standards.
The Crossblade and Crossblade NARO are on the US Army Authorized Protective Eyewear List and are RX compatible.
