    Red Dots vs. Green Dots

    To understand red vs green, let’s get into some science.

    First, it’s important to know that light is measured in wavelengths. The distance between the peaks is called nanometers. Those distances correlate to a number, and every color has a number.

    Since we’re talking about red vs green, we’ll keep to those colors. So, red is 625nm-740nm, while green is 520nm-565nm.

    Human vision cone spectrum
    Human vision spectrum, S=Small Cones, M=Medium, L=Long

    The long and medium cones in human eyes peak at 560nm and 530nm. As you can see in the image above, both are in the green area.  

    Yes, most of us can see red (sorry colorblind, pals), but we tend to be able to see more green — both in terms of shades and vibrance and also depth. In fact, the average person can see 30x as much green as any other color.

    So, our brains are wired to pick this color up faster and process it more easily.

    Decades of trial and error experimentation have proven that green delivers the best depth perception, which is why you’ll see it in night vision goggles and sights.

    Night Vision Cat
    Night Vision Cat through Gen 3 NVG

    Our eyes are basically designed to see more shades of this color, making it ideal for stealthy nighttime optics.

    But Why Aren’t All Dots Green, Then?

    You may be wondering why green isn’t more prevalent if our eyes do better with it…

    Science aside, it depends a lot on the person behind the optic.

    Everyone’s vision is a little different. You might do better with green, but your buddy’s eyes might work with red better.

    Sig Sauer P238 Shooting
    Editor-in-Chief Jacki has pretty bad astigmatism, so traditional red dots just don’t work for her.

    Generally speaking, though, if you’re older, have poor eyesight, or suffer from astigmatism — a green dot might work better for you.

    Personal factors aside, battery and close are other reasons these aren’t as popular.

    Trijicon MRO Green Dot Color Demonstration
    Green vs. Red in the Trijicon MRO.

    It takes a lot more power to run a green dot than it does a red. With a lot of consumers wanting long battery life and since most can see red dots fairly well, optics companies tend to produce red dots more.

    Also, the price of green dots is a little more than their red dot counterparts.

    Now that we’ve talked about red vs. green dots, let’s run through some of our top recommendations…

    5 Best Green Dot Optics

    1. Holosun HE510C-GR Elite

    Holosun is known for making affordable optics of good quality, and the Holosun HE510C-GR Elite is no exception.

    Holosun HE510C GR Elite (2)
    Holosun HE510C GR Elite

    This feature-rich model offers three reticle settings, a Titanium-alloy hood, solar battery assist, and Shake Awake.

    It also sports an internal battery tray which means you can replace batteries and not have to re-zero. That alone is a win.

    Holosun HE510C GR Elite (1)

    Speaking of battery life, the HE510C brings 50,000 hours of max battery life. That comes out to over 5 years or so. Not bad!

    In addition to an impressive battery life, this optic has a 32mmx24mm lens, offering plenty of visibility to see your target.

    The only thing you might want to watch out for is that exposed emitter. IMud, debris, or other junk could block it. That hasn’t happened to us yet, but it’s worth mentioning.

    Overall, we really dig this model and its durability. It’s a good blend of price and features.

    2. Trijicon MRO

    We can’t talk optics and not mention one of the biggest names in the game…Trijicon.

    This company is known for producing durable, reliable, and high-quality optics, and the MRO is no exception.

    Trijicon MRO on BCM 15 Studio
    Trijicon MRO on BCM 15

    Though its features err on the side of basic, this reflex sight really earns its keep in how bomb-proof it is. In terms of what it has to offer, it comes with a 25mm lens, great glass quality, and eight brightness levels.

    Battery life for the MRO sits at around a year.

    Trijicon MRO Point Firing

    Additionally, this optic comes with two night vision compatibility settings, so if night vision is your jam…look no future.

    The only downside to the MRO is the price. Edging closer to $500, it is a little pricey but it’s well worth the coin.

    3. Holosun HE507K-GR X2

    The Holosun HE507K-GR X2 is a great green dot perfect for your carry pistol.

    The 507K comes with multiple reticle settings and features solar battery assist, Shake Awake, and 50,000-hour battery life.

    Holosun HS507K X2 Shooting

    Additionally, the HE507K-GR X2 brings Lock Mode technology. This mode locks the buttons and prevents users from accidentally changing settings. This is a great way to ensure your settings don’t get messed with in your range bag.

    This Holosun also sports a side-mounted battery tray, so you don’t have to dismantle the whole thing to swap batteries. I really like this feature because, let’s face it, it’s a hassle to remove your red dot just for a battery change.

    Overall, the HE507K-GR X2 is a reliable and affordable option for those looking for a good pistol optic.

    4. Sig Sauer MSR Green Dot

    If you’re looking for an option to test the waters, then we highly recommend the Sig Sauer MSR.

    This optic is super budget friendly…like around $100. It’s a great way to dip your toes in the green dot pool and see if this option is the right one for you.

    Sig Sauer MPX K Shooting
    Sig Sauer MPX K topped with the MSR.

    The MSR ops for a 20,000-hour battery life as well as two night vision modes. It also comes with lens covers and a top-mounted battery compartment. We already talked about the convenience of battery compartments that are easy to access and don’t require removing the whole optic.

    To top it off, the MSR comes with a mount, so you’re ready to rock and roll with it straight out of the box.

    To put it simply, we think this is one of the best budget green dots on the market.

    5. EOTech XPS2-0GRN

    Want a holographic style but need that green dot? The EOTech XPS2-0GRN is the way to go.

    This optic is like most other EOTech designs in that it’s built to be durable. Seriously, these are pretty bomb-proof.

    We have even shattered the glass of an EOTech optic before, in the name of science, and it still ran.

    EOTech EXPS 3 Lens
    Science is fun!

    That’s about as good as it gets, folks.

    The dot itself is a nice, bright green that appears very crisp — even when magnified.

    Trijicon MRO Green Dot Color Demonstration Versus EOTech

    Battery life on this model is less than previous optics mentioned, sitting at around 600 hours BUT holographic sights pull some serious power.

    So, it’s not a surprise, and for a holographic and green dot, 600 hours is still pretty good.

    6. Viridian RFX35

    Viridian has a long-standing name in the green dot world and the RFX35 is a great addition to their lineup. The 6061 aluminum housing looks very similar to the Trijicon SRO and the footprint is the same as well.

    With that design, the shooter gets a large window, allowing for quick access and sight picture. The glass is also multi-coated to aid with visual clarity.

    Arex Delta M

    The RFX35 has a 3 MOA green dot and features instant on when moved. The buttons allow you to manually adjust between 8 daytime and 2 night vision settings.

    Of course, the green dot is IPX6 waterproof, and it is powered by a 2032 battery. Combining the instant on with a 2-minute back to sleep cycle, the RFX35 gets approximately 30,000 hours of use.

    Arex Delta M

    We tested this optic out with the Arex Delta Gen 2 and found it to be daylight bright, and very durable. Despite repeated efforts, we couldn’t beat the awake feature while drawing!

    Final Thoughts

    Green dots are a great way to get into optics if traditional red dots just don’t work for your eyes.

    Not to mention, for some, they can improve target acquisition times, offer better contrast, and an overall sharper reticle.

    Trijicon MRO Size Comparison with Other Optics

    While battery life and the larger price tag may be a limiter for some, we think these are solid models for those looking to jump into the green dot game.

      I just purchased the red and green dot Sig Sauer Romeo MSR and I am liking the green color better. I don't have astigmatism but I can pick up the green dot much better in any light situation. I paid the same amount for both. They say that the green will eat the battery life faster than the red, but you have to remember that using a green dot does not have to be as bright as a red dot to pick up. Just my opinion. I enjoy using both of them.

      "This hasn’t happened to either of my Holosuns so far, but I can certainly see the potential.

      Whenever this happens, I just wipe away the dirt and everything is good to go again. It’s a minor inconvenience, but it doesn’t distract or detract from my shooting in any way."

      Wait. So has it happened to you or not? This is very confusing because you appear to immediately contradict yourself.

      One added point. I served in USASOC in the late 90s. Red Dots were the rage (think old school COMP-Ms - ooh shiny!). Fast forward 20 years and that same red dot is bouncing all over the target. Why? Stigmatisms. 3 in the right, 2 in the left. So here's the choice - pay $750+ per eye to clear up my stigmatisms (and I will still need bifocals in less than 10 years), or get a combo red/green dot for a reflex site for 1/2 price, or get a straight green dot for 1/3 of the price. Choices and decisions.

I think I might prefer the multiple reticle version as well, since my G17 is mated to a MCK. Now to find the best deal. [crosses fingers]

      Green dots are just easier on my eyes, been preferring the larger MOA ring with a dot. 65 MOA ring for rifle, and 32 MOA ring for PCC. You left out the Sig Romeo5 with the predator green triangle... fun!

        Some finger nail polish on front irons is an old school way of getting some more contrast on ccw guns.

        Not sure it would help much on an AR since the front sight is further out.

        Can't hurt to try though.

      I recently put an Eotech XPS3 on a M4. It’s a great optic, the sight picture is phenomenal. I really debated on green or red, If my primary use was in daylight, I really think I would prefer green. However I decided on red for low light conditions.

        Yes, which is partly why I exchanged a Holosun 515GR for the red version. I also found I had an easier time associating red with "go" on targets, but I'm sure that could be trained away if I wanted.

        I bought one for my Scorpion and exchanged it for a red one. The optic is pretty solid, passing some pretty rough tests. The color is up to personal preference.

        If you are on the fence I suggest getting a cheap red and green optic with multiple reticles to test color preference. That also helped me learn circle dot reticles look cleaner to my eyes than single dots.
