AOSafety Beyond The Standard Eyewear Lens - Manual

Beyond The Standard™
EYEWEAR LENS COLOR REFERENCE GUIDE
For Industrial application purposes, this Lens Color Reference Guide will help you understand the
functionality of “task-specific” lenses and how to determine what type of lens is best for your
application and environment.
It is important to understand why there are more lens color options ,
often necessary, than a Clear, Gray or Mirror lens. The basic rule of thumb for choosing a lens is to
consider color opposites.
Blue is opposite of Yellow and Red is opposite of Green . Therefore, Red lenses
will absorb Green light and Yellow Lenses will absorb Blue/ Ultraviolet light, and vice versa . Try on the
different AOSafety lenses and learn for yourself the differences, functions and benefits of
the different lens colors.
Yellow/Contrast Amber Lens – absorbs Blue and Ultraviolet light
Use a Contrast Amber lens when sharpness, acuity and contrast are needed and to block high
intensity blue lighting such as UV and in Curing Operations. #1 Use is UV absorption.
•
Filters out hazy light that is hard on the eyes (everything seems brighter)
• Good for working outside at Dawn and Dusk
• Good for hazy, overcast or foggy days (because of the blue/gray light, similar to the function of a
fog light)
• Should not be used where protection from infrared radiation is required or for night time driving
Red / Vermilion Lens – absorbs some Green light
Sharpens visual acuity and provides a contrast similar to the Contrast Amber lens. Some people
prefer the Vermilion to the Amber lens when choosing a lens to sharpen visual acuity.
•
Good for inspections because you can see defects better – circuit boards, miniature components,
assembly items, etc.
• Filters out light that is hard on the eyes
• Not as good for outside at Dawn or Dusk as a Contrast Amber lens
Green/I.R. Shade Lens – blocks Red/Infrared (I.R.) light
Use any place where there is heat.
•
Good for metal making, furnace work, trash incineration and open flames
• Protects against glare, ultraviolet and infrared radiations
• Available in Shade 3.0 or 5.0
Gray/Silver Mirror/Blue Mirror Lenses – reduce glare and bright light
Use to reduce glare and/or to decrease visible brightness
•
Good for outdoor applications where a task specific lens is not required
• Can still recognize traffic and warning signals
• Provides good color recognition (utility workers and linespeople)
• Mirror reflects light, reducing the amount of light that passes through the lens
