AF4 Anti-fog Coating:
Provides excellent fog
prevention in high humidity environments where sudden
shifts in temperature occur.
Clear:
Provides excellent optics for general
applications where impact protection is required.
85% VLT.
Light Grey:
Serves the same purpose as grey lens,
yet allows more visible light through the lens for
indoor/outdoor use. Reduces glare from artificial
light such as halogen and fluorescent. 62% VLT
Grey:
For outdoor applications where light and
glare can cause eye strain and fatigue. 12% VLT.
Gradient:
For outdoor use where overhead glare
may interfere with visual acuity. 18% VLT.
Amber:
Blocks the blue portion of the visible
light spectrum, creating maximum contrast
enhancement, particularly in low light. 85% VLT.
Dark Green:
A general purpose lens that protects
from excessive glare and ultraviolet radiation.
12% VLT.
Fire, Blue Diamond, Emerald, Rainbow, Blue,Silver,
Banana Mirror and Copper:
For outdoor use where

Brown:
Outdoor applications where sunlight and
glare cause eye strain and fatigue. Meets color
traffic signal recognition requirements. 12% VLT.
Indoor/Outdoor Clear Mirror:
Allows more visible

for indoor inspection. 55% VLT.
Light Blue:
Allows more visible light through the lens
for indoor/outdoor use. Reduces glare from artificial
light such as halogen and fluorescent. 70% VLT.
Blue Ice:
Protects from excessive glare, high levels
of hazardous visible light and ultraviolet radiation in
outdoor applications. 33% VLT.
Filter Shades:
Protects against ultra-violet and
infrared radiation generated when working with
molten metal, and in welding, cutting, soldering
and brazing.
Polarized:
