Proper eye protection is ‘must-have’ gear for shooting sports. In addition to providing reliable impact protection, good shooting glasses should be comfortable, fog-free, and not interfere with your preferred hearing protection. Those who require corrective lenses also need to consider the various options available. In a past episode of their Weekly Gear Review, the 6.5 Guys discuss a variety of shooting glasses they have tried, including examples from DeCot, Oakley, and Wiley-X. Ed and Steve outline the key considerations when choosing eye protection, and then review practical aspects of eyewear design and construction that enhance comfort and functionality in the field.
The 6.5 Guys (Ed and Steve) offer a number of smart tips consider safety eyewear, helping you select the most effective safety glasses at an affordable price. Here are the 6.5 Guys’ KEY Take-aways when choosing shooting glasses, including prescription eyewear:
Key Things To Consider When Choosing Eye Protection
1. Avoid polarized lenses or lenses that reduce light transmission significantly (except for action shooting in very bright conditions with large, close targets).
2. Avoid frame designs that interfere with prone shooting.
3. Avoid designs that easily fog.
4. Avoid frame designs with thicker temples that are uncomfortable to wear underneath hearing protection.
5. Select lenses with an appropriate degree of ballistic protection. CLICK HERE to learn more about eyewear safety standards.
6. When you get your prescription, be sure your ophthalmologist includes the interpupillary distance. This is a critical measurement particularly for heavier prescriptions.
7. If you have a complicated prescription select a vendor who will actually spend time with you to address any concerns.
Horrific .50 BMG Kaboom — Eye Saved by Protective Eyewear
Think you don’t need eye protection? Watch this video starting at 4:10. The screw-on barrel “cap” (chamber closure) of the .50 BMG action flies into the shooter’s face. Without eye protection the shooter would have definitely lost his right eye. (See video at 5:20 for analysis).
Safety First — Your Eyes Are Irreplaceable
Accurate shooting begins and ends with the human eye. Your career as a marksman could be cut short if you don’t use good eye protection every time you go to the range and/or handle a firearm.
Every year, over 1,000,000 people suffer serious eye injuries. Shooting is hazardous; it is estimated that there are 30,000 firearms-related eye injuries each year (if you include paintball sports.) After paintball, general hunting accidents comprise most firearms-related eye injuries.
Quality eye protection need not be expensive. You can find comfortable, ANSI Z87.1-certified shooting glasses for under $10.00.
If you select shooting glasses carefully, and ensure that your eyewear is safety-certified, inexpensive shooting glasses can perform very well. But you need to avoid cheap, soft-plastic lenses that claim “impact resistance” without satisfying a testing standard.
With the price of premium scopes approaching $3400.00 (and beyond), it’s more important than ever to provide extra protection for your expensive optics. ScopeCoat produces covers that shield scopes with a layer of neoprene rubber (wetsuit material) sandwiched between nylon. In addition to its basic covers, sold in a variety of sizes and colors, ScopeCoat has a line of heavy-duty 6mm-thick XP-6 covers that provide added security. CLICK HERE to review the full line of ScopeCoats on Amazon.
Triple-Thickness XP-6 Model for Added Protection
The XP-6 Flak Jacket™ is specifically designed for extra protection and durability. The 6mm-thick layer of neoprene is three times thicker than the standard ScopeCoat. XP-6 Flak Jackets are designed for tall turrets, with sizes that accommodate either two or three adjustment knobs (for both side-focus and front-focus parallax models). To shield an expensive NightForce, March, or Schmidt & Bender scope, this a good choice. XP-6 covers come in black color only, and are available for both rifle-scopes and spotting scopes.
The heavily padded XP-6 Flak Jacket is also offered in a Zippered version, shown at right. This is designed for removable optics that need protection when in storage. The full-length, zippered closure goes on quick-and-easy and provides more complete protection against dust, shock, and moisture. The line of XP-6 Scope Covers run $23 – $34 on Amazon.
Special Covers for Binos and Red-Dots
ScopeCoat offers many specialized products, including oversize covers for spotting scopes, protective “Bino-Bibs” for binoculars, rangefinder covers, even sleeves for small pistol scopes and red-dot optics. There are also custom-designed covers for the popular Eotech and Trijicon tactical optics.

When shopping for a new riflescope or spotting scope it’s easy to get confused by all the technical terminology. Do you wish you had a better way to compare scopes — beyond just size, weight, and price? Well Swarovski Optik can help. The Swarovski Hunting Blog offers a helpful guide to technical terms used when comparing scope specifications. Here are some important definitions, expressed in layman’s language:
Objective Lens Diameter
The objective lens diameter determines the size of the optical system’s entrance pupil. The bigger the objective lens diameter, the more light the system can capture. However, the size of the objective lens does not determine the size of the field of view.
Exit Pupil
The size of the Exit Pupil is determined by the objective lens diameter and the magnification. If you look at the eyepiece from a distance of around 30 cm (11.8 in), the Exit Pupil appears as a bright disc.
For calculating the Exit Pupil the formula is:
Exit Pupil = objective lens diameter ÷ magnification (expressed in power number).
The larger the Exit Pupil, the more light will reach the eye.
Field of View
The Field of View is the size of the circular section of the area which can be observed when you look through a long-range optical device. In the case of rifle scopes, it is specified at a distance of 100 meters or 100 yards. For example, 42.5 m at 100 m or 127.5″ at 100 yards. As an alternative, the Field of View can also be stated in degrees (e.g. 6.6°).
NOTE: The technically-feasible size for the Field of View is essentially determined by the magnification. The higher the magnification the smaller the Field of View.
Twilight Factor
The Twilight Factor defines the optical system’s performance in poor light. The statement “the greater the twilight factor, the better the suitability for twilight” only applies if the exit pupil is larger than or at least as big as the eye’s pupil. The pupil in the human eye can only open to around 8 mm. As we get older, our eyes become less flexible, which limits our ability to see things in twilight or at night. Therefore [an optic’s] exit pupil cannot always be fully utilized.
For calculating the Twilight Factor the formula is:
Twilight Factor = root of ( magnification x objective lens diameter ).
NOTE: Spotting scopes have extremely high twilight factors because of their high magnification and large objective lens diameter. But [when used at high magnification] their small exit pupil can make them [somewhat difficult] to use in twilight.
The Swarovski Optik website features a blog with interesting technical articles. In the “On Target” series of blog stories, Swarovski has provided a handy explanation of how optics systems work, with exploded diagrams of rifle scopes, spotting scopes, and binoculars. CLICK HERE for Swarovski Optics Blog.
Scope Terminology Focusing Lens
The focusing lens is an adjustable lens inside the optical system for focusing the image at different distances…. In the case of rifle scopes, apart from focusing, the focusing lens also facilitates parallax compensation.
Diopter Adjustment
For rifle scopes, the reticle can be focused using the diopter adjustment on the eyepiece, thereby correcting any visual impairment. [Editor’s Note: Movable eyepiece diopter adjustment is not offered on all rifle scopes. It is a useful feature on Swarovski and other premium scopes. This allows shooters who need eyeglasses to get a sharply focus image even without wearing corrective lenses. Of course shooters should always wear ANSI-certified eye protection. With the diopter, folks who need correction can use inexpensive, non-Rx safety eyewear instead of expensive prescription safety glasses.]
Reversal System
The purpose of the reversal system is to reverse the image by means of prisms in binoculars and telescopes, and lenses in rifle scopes….The lens reversal system is needed in rifle scopes to control the variable magnification and move the exit pupil[.]
Parallax Explained
What is Parallax? What problems can Parallax create when you are shooting? Many novice shooters can’t answer those questions easily. Likewise, many folks don’t understand how to use their front or side-focus parallax controls most effectively. Yes the parallax control basically sharpen focus at different target distances — but there’s more involved. This video offers helpful insights.

Do you find that the crosshairs in your scope get blurry after a while, or that you experience eye strain during a match? This is normal, particularly as you get older. Focusing intensely on your target (through the scope or over iron sights) for an extended period of time can cause eye strain. Thankfully, there are things you can do to reduce eye fatigue. For one — breathe deeper to take in more oxygen. Secondly, give your eyes a break between shots, looking away from the scope or sights.
In our Forum there is an interesting thread about vision and eye fatigue. One Forum member observed: “I have noticed recently that if I linger on the target for too long the crosshairs begin to blur and the whole image gradually darkens as if a cloud passed over the sun. I do wear contacts and wonder if that’s the problem. Anyone else experienced this? — Tommy”
Forum members advised Tommy to relax and breath deep. Increase oxygen intake and also move the eyes off the target for a bit. Closing the eyes briefly between shots can also relieve eye strain. Tommy found this improved the situation.
Keith G. noted: “Make sure you are still breathing… [your condition] sounds similar to the symptoms of holding one’s breath.”
Phil H. explained: “Tom — Our eyes are tremendous oxygen hogs. What you are witnessing is caused by lack of oxygen. When this happens, get off the sights, stare at the grass (most people’s eyes find the color green relaxing), breath, then get back on the rifle. Working on your cardio can help immensely. Worked for me when I shot Palma. Those aperture sights were a bear! The better my cardio got the better and longer I could see. Same thing with scopes. Try it!”
Watercam concurred: “+1 on breathing. Take a long slow deep breath, exhale and break shot. Also make sure you take a moment to look at the horizon without looking through rifle or spotting scope once in a while to fight fatigue. Same thing happens when using iron sights.”
Arizona shooter Scott Harris offered this advice: “To some extent, [blurring vision] happens to anyone staring at something for a long time. I try to keep vision crisp by getting the shot off in a timely fashion or close the eyes briefly to refresh them. Also keep moisturized and protect against wind with wrap-around glasses”.
Breathing Better and Relaxing the Eyes Really Worked…
Tommy, the shooter with the eye problem, said his vision improved after he worked on his breathing and gave his eyes a rest between shots: “Thanks guys. These techniques shrunk my group just a bit and every little bit helps.”
Read more tips on reducing eye fatigue in our Forum Thread: That Vision Thing.
To avoid eye fatigue, take your eyes away from the scope between shots, and look at something nearby (or even close your eyes briefly). Also work on your breathing and don’t hold your breath too long — that robs your system of oxygen.

If you’re one of those folks who doesn’t wear eye protection, you need to check out the LuckyGunner Labs Eye Protection Test. For those who DO wear safety glasses — don’t assume that everything is OK. Just because you purchased name-brand “safety glasses” doesn’t mean that you are getting truly effective protection. In fact, many forms of protective eyewear sold today are flimsy, or poorly made. Consequently, they won’t stop even low-energy, slow-velocity fragments.
Two years ago, LuckyGunner Labs conducted very extensive field tests of 28 types of eyewear, ranging in price from $7 to $220. Remarkably, some of the most expensive safety eyewear performed no better than $10 items. Many of the products failed shockingly — with the lenses coming right out of the frames when hit with pellets. LuckyGunner recorded these kind of failures even with ANSI Z87-“approved” eyewear. The reason is that the Z87 test is not tough enough: “The basic ANSI standard is referred to as Z87, and you’ll see this marked in a number of locations on most eye protection marketed to shooters. However, the Z87 impact standard involves a .25″ steel ball traveling at 150 fps — this is fine for protecting eyes from debris that might fall or be thrown, but is not extremely relevant to shooters, who are dealing with objects traveling at much higher velocities.”
Standard
Impact speed
Caliber/Size
ANSI Z87.1-2003
High Velocity
150 feet/second
45 meters/second
0.25″ diameter steel ball
(25 caliber)
Mil-PRF-31013
Vo ballistic test
640-660 feet/second
195 meters/second
0.15 inch diameter steel projectile (15 caliber)
The testers recommend you select eyewear that meets military specification (above and beyond ANSI Z87). The MIL-PRF-31013 Standard covers projectiles up to 650 feet per second. This is much more stringent. Additionally, you want to replace often-used protective eyewear every year or so. Long-term exposure to UV radiation can weaken polycarbonate and lessen its ability to withstand impacts.
SUMMARY — What to Look for in Protective Eyewear
THE GOOD — Eyewear Protects Against Direct Hit with .22 Short Bullet
APEL Revision Sawfly eyewear was shot with a .22 Short, pushing a 29 grain bullet at 710 fps. That’s not powerful by modern firearm standards, but this might be fairly representative of a ricochet bullet fragment. The Sawfly lens stopped this 29gr bullet with minimal damage to the cheek area.
THE BAD — Remington Eyewear Lenses Separate. Right Lens Enters Eye Socket
The most gruesome example was the cheap Remington eyewear which shed both lenses back towards the eyes, one of which embedded itself into the eye socket. The real-world implications of this action are disturbing to say the least.
THE UGLY — Prescription Glasses Failed Miserably
Many ranges don’t see any need for protective eyewear beyond prescription glasses. However, most prescription lenses offer little if any protection. If the prescription lenses are glass, this can create more problems. As shown below, these prescription glasses offered no ballistic protection, and, in fact, proved more dangerous to the eyes due to the flying glass shards.
Results Chart, Video Clips, and Photos copyrightLuckygunner.com.
Summary and Conclusions:
For faster-moving projectiles such as ricochet fragments, you need high quality, tested eye protection. LuckyGunner recommends eyewear with a single (one-piece) lens for any activity where your face might be struck by small, fast-moving objects. Individual lenses detach from the frames once a certain level of force is reached, and they are driven back into the eye sockets, where considerable damage may be done. There are good examples of protective eyewear with two separate lenses, but a broad, one-piece lens distributes force much better.
A wide, comfortable, and preferably soft rubber nosepiece is critical. Along with good “arms”, this will serve to keep the eye protection in place and will also reduce the chances of the lens being driven down or back into the face with enough force to damage the orbital bones.
A frame that connects across the top of the lens, not individual arms which attach to the outside corners of the lens, is recommended. This will reduce the chances of the lens detaching from the frame under impact (it’s still possible, just less likely). Some types of eye protection actually use the frame to absorb impact and distribute force.

What is the most-used piece of equipment on this editor’s reloading bench? No it’s not my Rock-Chucker press, or even my calipers. The one item in near-constant use is a small, folding magnifying glass. Mine folds into a square case and offers 4X viewing with an 8X bifocal insert. With this handy tool I can inspect case mouths for burrs, check primer pockets, inspect meplats, and look for flaws on bullet jackets. I also use the magnifier to see rifling marks on bullets seated into the rifling, or check my bolt for galling. The number of uses is nearly endless. I keep one magnifier at my reloading bench and another in my range kit.
Folding magnifiers are so handy yet inexpensive that you should own a couple spares (including one in the range box). I bought my magnifier in a book-store, but you can also find them on the web at FoldingMagnifier.com and WidgetSupply.com starting at just $1.95. To see the finest details, Widget Supply offers a powerful 9X/18X slide-out magnifier with a built-in, battery-powered LED light. With that gadget, you can easily see any minute flaws in your barrel crowns. That’s important because crown damage can cause hard-to-diagnose accuracy issues. We’ve known guys who spend weeks tinkering with loads, when the real problem was a worn-out or damaged crown.

There is one subject as to which we should all be in agreement — the need to wear quality, protective eyewear whenever one uses a firearm. Sadly, it’s not uncommon, at the range, to see shooters wearing no eye protection, or wearing cheap, “dime-store” glasses that can shatter on impact.
This video from Luckygunner Labs shows what can happen with low-quality eyewear. When hit with pellets, the left lens came out and the right lens entered the eye socket!
Read Our Guide to Protective Eyewear
We’ve created a comprehensive Guide to Protective Eyewear. Forum member ChuckW2 told us: “That was the most important article that has ever been posted on this site. I am amazed how many people do not wear glasses while shooting or hunting. Great read….” If you haven’t done so already, read the story. We guarantee you’ll learn something new.
The Eyewear Guide explains the safety standards that apply to protective eyewear and reviews the best lens materials currently available including Polycarbonate, Trivex™, and SR-91. You may not have heard of Trivex, but it is probably the best material out there right now — it’s tough, lightweight, and has better optical properties than Polycarbonate. SR-91 is a good choice for those who need a polarized lens. Our Eyewear Guide also includes a section by Danny Reever on Prescription Shooting Glasses. Danny discusses the available options in lens materials and has many helpful recommendations.
Along with our reviews of lens materials, tint properties, and frame design, we highlight a study done by the NRA’s American Hunter magazine. 10 popular brands of eyewear were tested, with some very interesting results. The testers observed that price does not necessarily assure quality. Relatively inexpensive Bollé VX and Pyramex eyewear both worked better than some expensive brands.
On the other hand, don’t select eyewear simply because it’s cheap or easy to find. American Hunter editor Jeff Johnston observed: “It’s a mistake to assume that any plastic-lens sunglasses off the rack at the local 7-11 are made of polycarbonate and therefore are effective as shooting glasses—cheap plastics are not polycarbonates; in fact, wearing them could be worse than wearing nothing, as they can introduce sharp shards of plastic to your eyes in addition to the projectile(s) that caused them to break.”

Based on its external appearance, a modern riflescope may seem simple. It’s just a tube with two or three knobs on the outside right? Well, looks can be deceiving. Modern variable focal-length optics are complex systems with lots of internal parts. Modern scopes, even ‘budget’ optics, use multiple lens elements to allow variable magnification levels and parallax adjustment. We had a chance to look inside a riflescope thanks to a product display from ATK, parent of Alliant Powder, CCI, Federal, RCBS, Speer, Weaver Optics. ATK sliced open a Weaver Super Slam scope so you can see the internal lens elements plus the elevation and windage controls. We thought readers would like to see the “inner workings” of a typical modern rifle scope, so we snapped some pictures. The sectioned Super Slam scope was mounted inside a Plexiglas case, making it a bit hard to get super-sharp images, but you can still see the multiple lenses and the complex windage and elevation controls.
