Standard Lenses—Clear, Amber, and Neutral Gray
All Gentex standard visor lenses offer advanced protection while enhancing visual acuity.
Basic ballistic and impact protection is provided with Gentex clear lenses. Using specially developed dyes and colors, Gentex also offers Amber and Neutral Gray lenses to enhance visual acuity in more demanding flight or terrain conditions. In addition to the protection offered by our clear lenses, our amber lenses are engineered with yellow hue to offer basic contrast to the field of view in hazy or foggy conditions, and our neutral gray lenses were developed to provide sun glare protection.
For more advanced mission needs, Gentex has developed high-contrast and gradient lenses.
High Contrast Lenses
Specially engineered for use in snow, haze, and fog conditions, Gentex high contrast lenses provides aircrew with a heightened and enhanced field of vision when flying in low-light conditions, such as foggy, overcast, hazy, or cloudy environments. Gentex Filtron technology-absorber dyes that are molded into the polycarbonate optic renders the lens a unique yellow color, and filters certain invisible and visible wavelengths for the wearer. This advanced lens creates a viewing field where all blue components appear black or very dark, and other color components are nearly normal.
Engineered specifically for protection against sun glare, Gentex gradient lenses allow aircrew to see instrumentation clearly. The tinted and standard neutral gray color at the top of the lens transitions to clear at the bottom.
