Hunters - Choosing a Lens Color

If you’re a shooter, you already know that shooting safety glasses are an absolute necessity every time you hold a gun, whether it’s at the shooting range, in the field, or as part of your job. There’s no mystery surrounding why shooting glasses are a critical accessory – your eyes are precious, and you need to protect them. Yet, there can be some mystery around the many lens color options you have to choose from for your shooting safety glasses. 


Different safety glasses lens colors enhance your vision in various lighting conditions, helping you see with more clarity and accuracy – two characteristics that every shooter needs. Let’s break down your shooting glasses lens color options:
Yellow/Orange Shooting Glasses: Yellow and orange tinted safety glasses, tend to block out “blue light”, such as light on a cloudy day, but bring out the orange color of a practice target. These colors tend to create a more detailed line of vision, helping you to better perceive depth, and thus improve accuracy.
Amber Shooting Glasses: Amber lenses, are a very popular lens color, and they work best in low light, cloudy days. The amber tint creates exceptional contrast between colors, helping the orange of the target stand out to you, even on those dreary days.
Purple Shooting Glasses: If you’re at a shooting range with a backdrop of beautiful trees around you, you’ll want the help of a purple safety glass tint. This color helps improve contrast, particularly against greens (trees/grass) and oranges (the target), keeping your eyes focused on the target, and only the target.
Brown Shooting Glasses: Many hunters and shooters prefer brown lenses, as they call attention to orange targets. They work best in fields or other open areas, and particularly in bright sunlight.
Which shooting safety glasses lens color is ideal for you, and why? Every shooter has their preferred color they feel most comfortable with and would recommend, and we’d love to hear from you on the lens colors that work best for your shooting conditions. Start taking notice of the different lighting and landscape conditions around where you shoot, and match these characteristics up to the lens color that would be just right for you.

Improve Visibility with Randolph Eyewear Ranger Collection - Yellow Lenses increase Contrast


My eyes often feel tired after staring at the computer all day. So I'm wondering if glasses designed for computer use actually help (for example, those yellow-tinted glasses I've seen on Randolph Eyewear. They seem pricey and I'm a little skeptical about all the claims, but I also want to protect my vision. 

Vision problems are unfortunately one of the hazards of too much screen time. In fact, theVision Council found that 70 percent of US adults in one survey reported having some kind of digital eye strain (strained, dry, or red eyes; blurred vision; headaches; back pain; neck pain; or general fatigue) as a result of using digital devices for hours at a time.P
We've previously noted several ways to prevent or reduce eyestrain, including using the 20-20-20 rule to regularly give your eyes a break and ergonomically optimizing your workstation. In addition to those essential tweaks, computer eyewear could also alleviate or prevent digital eyestrain, depending on your situation. I talked to several eye health experts to find out more about these special glasses, and also did a two-week trial comparing new specially-coated glasses with older ones. Here's what I learned.

Computer glasses are special-purpose eyeglasses meant to optimize your eyesight when you're looking at digital screens. They're designed to: reduce glare (a major cause of eyestrain), increase contrast, and maximize what you see through the lenses—making it easier to look at a screen for longer periods of time. P


Validating my experience, Dr. Jeffrey Anshel, an optometrist and computer vision consultant (who was also the technical adviser for Gunnar Optiks), points out that when it comes to coatings, you have two general choices: old and new. Older ones do peel and "craze," resulting in unsightly cracks, while newer ones wear very well and have a one-year warranty. So when you're at the eye doctor, you'll want to ask for the latest coating—and perhaps buy new glasses even if your prescription hasn't changed in the last few years, because coatings definitely have improved.
PAnti-reflective (AR) coating
: Anti-reflective coatings reduce glare bouncing off screens and from light sources. Specially-designed Randolph Ranger Sporting Eyewear offers these coatings and prescription glasses can get anti-reflective coatings as well. 
Color tints: Some computer glasses also have an unmistakable (usually yellow) tint designed to increase the contrast on the screen and filter out the uncomfortable/harsh light spectrums so your eye muscles relax. 
P
The Yellow lenses found on Randolph Eyewear are perfect for sitting in front of the computer for long amounts of time, and perfect for dusk-night driving.  These glasses increase contrast and make it safer for you to be on the road.  They are also perfect for sporting activities like hunting, hiking, fishing, biking, and anything else you might be doing ourdoors.  Randolph Eyewear makes is safer for your eyes all day and transitioning into the night.

Sunglasses are more than a Fashion Statement


Sunglasses aren’t just fashion accessories. They are a necessary protection for the eyes. Most consumers know about the danger of sun exposure to the skin, but many are unaware that the sun’s rays can damage the eyes. To correctly shield the eyes, the right type of sunglasses must be worn, especially since wearing the 
wrong type can cause more damage than not wearing glasses at all. 
The eyes are susceptible to being burned by sunrays. The cornea, lens, and retina are all vulnerable to overexposure of ultraviolet (UV) rays. Over time these UV rays—invisible to the human eye—can harm the eye if left unprotected. Workers who are heavily exposed to sunlight should protect their eyes with UVblocking sunglasses.Sunglasses help in two important ways. They filter light and protect the eyes from damaging UV rays. Long-term exposure to UV rays can lead to cataracts, macular degeneration, or skin cancer around the eyelids. Sunglasses should be worn outdoors to protect the eyes.

Choose Your Color Wisely
Different lens tints filter different wavelengths of light. Some may enhance or distort colors and affect contrast. Select tint based on need.
• Green—Allows true color perception and good contrast in bright light; reduces eyestrain in bright light.
• Gray—Allows true color perception, but does not enhance contrast; good for cycling or running.
• Brown—Good in hazy sun, enhances contrast; good for high-glare environments.
• Amber—Brightens cloudy, hazy, or foggy skies; excellent for contrast; minimizes eyestrain; distorts color (images look yellow-orange).
• Yellow—Improves contrast and depth perception in low light; good for overcast days.
• Red—Excellent depth perception in low light; contrast objects against blue or green backgrounds.
• Mirrored—Reflects high-intensity light to reduce glare; available in various colors.

Do those sunglasses for specific sports really make a difference?
Yes. Sports eyewear in general tends to be safer than regular sunglasses because the lenses and frames are made of special materials that are unlikely to shatter if struck and can give you the benefits of both sunglasses and protective eyewear.
Also, certain lens colors in performance sunglasses can enhance your vision for certain sports; brown, for example, is popular with golfers because it provides nice contrast on those very green golf courses.
Randolph Eyewear is some of the best made eyewear on the market today.  Every pair is handmade in the USA using the best materials available.  Randolph gives a lifetime warranty on their solder joints, which means this may just be the last pair of sunglasses you will ever have to buy.  These glasses were first made to protect the eyes and increase visibility for air force pilots, and now they are available to the general public.
