The Hollis M1 Mask raises the bar for optical quality and distortion free vision. The lens is an extra clear glass which has advanced optical qualities.
Low iron content in the glass produces a higher light transmittance and a reduced green tint inherent in other glasses.
This makes the lens distortion free and helps improve colour and visibility in low light conditions underwater.
