Frequently Asked Questions

Yes! Magna Lens® offers magnetic adapter kits so that you can add magnetic attachment points to your existing earmuffs, which will allow you to use the Magna Lens® eyewear. This adapter kit is compatible with most models of popular earmuff brands. If you are unsure as to what option is best for you, or do not see an adapter for your brand of earmuffs, then please feel free to contact us. We may have a solution for you that is not listed on our website or we may be able to provide you with a customer magnetic earmuff adapter.

Our safety eyewear has adjustable side components so that they can fit just about any size face or head. Our ML Pro™ model of eyewear also comes with 3 sizes of magnetic temple pieces for an even more streamlined look.

Since they magnetically attach to the earmuffs, the tendency to slide down your nose is eliminated. You will be able to wear your eye ear protection for long periods of time without the need to keep adjusting or pushing up your eyewear.

If for whatever reason you are not thrilled with your Magna Lens® eyewear, then you may simply return them within 60 days and we will gladly issue you a full refund. Please do not hesitate to contact us with any questions.

Magna Lens® offers an optional snap-in prescription frame (Rx to be added by an optometrist or can be provided by us with a prescription - simply use our contact form to contact us for details). This prescription frame insert is easily installed on the inside of your Magna Lens® one-piece wrap-around lens. Please visit our "Instructions" page for a video demonstration.

Absolutely! Magna Lens® specialized technology enhances color, visual acuity, superior Blue Light and HEV (High Energy Visible Light) management, contrast and environmental performance.

Magna Lens® premium lenses increase the range of the visual light spectrum for magnified contrast of the target against the background environment. With consistent color manufacturing, Magna Lens lenses deliver true, sharp, edge-to-edge color and high resolution optical performance. Great for all tactical situations and shooting sports; clay, trap, skeet, hunting, pistol, rifle and more.

All Magna Lens® lenses meet or exceed all standards for optics, UV, blue and HEV blocking, ANSI impact and cosmetics.

ML Pro™ Grey
Luminous Transmission 25.3%

• Passes ANSI, ISO standards with 100% UV protection and Blue Light and HEV protection to 400 nm and beyond.
  

• Yes, Magna Lens® colored lenses provide 100% UV protection and additionally provide extra coverage of HEV (High Energy Visible Light).
• The sun emits 3 types of UV waves - UVA, UVB and UVC. Both UVA and UVB make it through to the earth's surface. UVC (the most dangerous) on the other hand is mostly absorbed by the earth's atmosphere.
• 95% of UV radiation that makes it to the earth is UVA (this is also what is used in tanning beds). The other 5% is UVB (which is what causes most sunburns). Both types of radiation have been found to cause damage if directly exposed to our eyes.

• Magna Lens® colored lenses provide Blue Light protection beyond most other lenses, with protection up to 420+ nm’s which includes protection from HEV – High Energy Visible Light (above 400 nm).
• High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.

No, both are blocking 100% of the sun's harmful UVA and UVB radiation. As long as your sunglasses offer this protection (like all Magna Lens® lenses do) you can rest easy and always perform your best!

Our Magna Lens® eyewear can be used with just about any brand of earmuffs. We offer our own earmuffs with built-in neodymium magnets to work with the Magna Lens® eyewear system. Our passive earmuffs are configurable from a full configuration to a slim configuration, and our electronic earmuffs come in either a full or slim configuration.

The Noise Reduction Rating (NRR) of the full size electronic and passive earmuffs in their full configuration is 25. Our slim size electronic earmuffs have a NRR of 21. These ratings are uniquely maintained with Magna Lens eyewear that does not disrupt the seal of the earmuff pads, preserving between 2 and 17 dB of sound attenuation compared to traditional eyewear.

Yes and No. While many earmuff models offer similar noise reduction ratings (without eyewear), the Magna Lens® design eliminates the gap in the earmuff cushion caused by eyewear. This gap can reduce your earmuff noise reduction rating anywhere from 2 to 17 dB depending on eyewear design. This means that your 25 NRR earmuffs may be performing as low as 8 NRR with traditional eyewear.

Here are some approximate noise ratings for various firearms (indoor range tests):

.22LR pistol 154-158 dB

.45 auto pistol 158-163 dB

.40 S&W pistol 158-161 dB

9mm pistol 160-163 dB

.357 handgun 167-172 dB

12ga shotgun 158-160 dB

.556 rifle 165-167 dB

The National Institute of Occupational Safety and Health (NIOSH) has a formula for calculating safe levels of noise exposure as related to high level noise impulses such as firearm discharges. Below are some of the acceptable exposures based upon this formula.

One 140 dB (decibel) noise impulse in a 24 hour period

Ten 130 dB (decibel) noise impulses in a 24 hour period

Thirty-two 125 dB (decibel) noise impulses in a 24 hour period

One hundred 120 dB (decibel) noise impulses in a 24 hour period

Three hundred and sixteen 115 dB (decibel) noise impulses in a 24 hour period

One thousand 110 dB (decibel) noise impulses in a 24 hour period

You want to keep your noise impulse exposure within the recommended levels shown above.  If you are using a standard set of earmuffs that have a 25 dB noise reduction rating, then you would subtract the NRR rating from the level of the noise impulses you are being exposed to. A .22LR pistol at an indoor range will generate an impulse of approximately 155 dB.  So when you subtract the 25 dB rating from the 155 dB noise impulse you will be exposing yourself to 130 dB.  According to NIOSH you will exceed your limit after ten rounds fired.

The Magna Lens® system will help preserve the noise attenuation of your earmuffs compared to traditional eyewear with an over-the-ear frame design, however even with the Magna Lens® system, it is important to remember that all earmuffs have their protective limits. As you see above, the risk increases with repeated sound exposures.

One smart safety option is to wear in-the-ear plugs along with over-the-ear earmuffs. If you add soft expandable earplugs, in addition to your earmuffs, you will add approximately 18-20 dB of additional protection on top of your earmuff rating. This will greatly extend your shooting time.
