Red Dot VS Green Dot

In the world of optics, I often come across the debate about green dot and red dot sights. Both have their advantages, and it usually comes down to personal preference. But there's more to it. I will explore the differences between these two illuminations to help me determine which is the best choice for my needs.

My decision between red and green dot sights should be based on my specific needs, preferences, and the conditions where I will use the sight. I should try both types if possible and choose the one that feels right for me.

Green Dot Sight

  • Green dot sights: increasing in popularity due to better visibility in various lighting.
  • Daylight use: green dots are easier on the eyes, reducing eye fatigue.
  • Dusk or low light: red dots become more effective, standing out against dark backgrounds, ideal for evening hunting.

Red Dot Sight

  • Longer Battery Life: Red dots have longer wavelengths, using less energy than green dots.
  • Night Operations: Stand out against night vision displays' green backdrop, making red dots more visible and preferred for night use.

Red Vs Green Dot Visibility

red vs green dot sight

While most people prefer a green dot to be more visible under daylight shooting environment. Both dot colors are actually very easy to pick up for shooters with normal eye sight.

We've got around 120 million rods and about 6 million cones in there. Now, rods are super sensitive to light, which is why they're great for helping us see when it's dark. But they don't do colors, just light intensity, so that's why everything looks kind of grayish in the dark.

Then there are the cones, which are fewer but really important for seeing colors. They work best in bright light. We have three types of cones, and each one picks up different colors - red, green, and blue. That's how we get to enjoy all the colors around us.


The cones aren't spread out evenly in our eyes. The center part, called the fovea, has more cones. That's why we see things so clearly and in full color right in the center of our vision. About 60% of our cones are good at detecting red, 30% for green, and 10% for blue, which is why some colors can seem brighter or easier to spot.

Like with green - our eyes are really good at picking it up, especially in bright light. That's why green things can look more vibrant than red things in daylight. This is super useful in activities like target shooting. Both green and red dots are used for aiming, but depending on the color of the target, one might be easier to see than the other.

So, both red and green dots work for shooting, but if the target color kind of blends with the dot color, it might be tough to see. That's something shooters think about when they're choosing what color dot to use.

Green Vs Red Dot Astigmatism

If you've got astigmatism, a red dot, especially in reflex sights, might not look right. It could look like it's bursting out into stars or like there are multiple dots instead of just one.

Now, green dots tend to be clearer for folks with issues like astigmatism based on perception. They still the same kind of distortion that you might get with red dots if your eyes have refractive error.

Green dot makes a strong argument, but the choice varies for every shooter. Personal likes, uses, and past experiences matter a lot. What matters the most is to train. Dot color really doesn't matter that much.
