Lens Technology

From any shooting discipline to fishing and hunting, quality lenses will not only protect your eyes from numerous hazards, they’ll actually elevate your performance and prevent your eyes from becoming fatigued. Those who are serious about the quality of their vision depend on Ranger lenses to perform, no matter the goal.

Although all Ranger lenses absorb 100% of UV rays and are molded at above industry standard thickness for your protection, the best advantages to wearing our lenses are enhanced definition and optical clarity. Unlike other shooting lenses, Rangers are made with distortion-free optical-grade polycarbonate. This gives you the level of protection you need while not compromising the quality of your vision.

We don’t have flashy names for our basic lens tints- An orange lens is called “Orange”. This straight-forward approach is designed to assist you in choosing the correct lens tint for any given situation. With over 15 tints to choose from, you can be sure you’ll find the tints you need to enhance your performance.

Choosing the right lenses

Any serious shooter or outdoor enthusiast will benefit from the right lens tints, although choosing which tints will work for you can be difficult. Here are 3 important factors to consider while selecting your tints:
Confidence Level – What tints have you used in the past? Most likely, the tint you’re most accustomed to will give you the most comfort and confidence while shooting.

Light Conditions – The trick is to get your eyes as focused as possible. Your pupils regulate the amount of light that enters your eyes – just like a camera shutter. In low light, your pupils enlarge to allow more light into your eyes. As a result, your eyes become less focused. In bright light, your pupils decrease in size and allow your eyes to focus on distant objects. A simple rule to get maximum focus on a target is to use a lens tint that lets as much light in as possible without squinting your eyes. To follow this rule, you’ll need different lens tints to use in varying light conditions.

Background – What background are your targets in front of? You’ll want to use different lens tints according to the colors of your background to highlight your target. For instance, if you’re shooting orange clay targets in front of green trees, you’ll most likely want purple or vermilion lenses that dull greens and highlight oranges. If your background has glare, such as water, you’ll most likely want to use a polarized lens. See the tint descriptions on the next page as a guide to help you choose the lenses that are right for you.

Over 15 tints are available, each named after the color of the lenses – to make it easy and efficient for you to choose. In order to select the best tint for you, we advise that you consider the light conditions and always use a tint that allows the maximum amount light to enter without needing to squint your eyes. You’ll also want to check that the lens tint spotlights your targets adequately against their background. Remember that each respective tint will upgrade performance under different conditions, and you may need to have a few tints of Randolph Ranger glasses on hand to compensate for changes in your surroundings. To cite a few popular examples of our lens tints:

  • Medium Yellow (our most common yellow tint) is highly effective at highlighting orange clay targets and upgrading contrast when light is minimal.
  • Brown is ideal for diminishing light under very bright conditions and for identifying the brown hues of game birds.
  • Vermilion is extraordinary for shooting when you’re surrounded by bright greenery. It spotlights orange hues while toning down the green, and it gives people with color vision deficiency a new edge on shooting well.
