Green dot instead of Red

Green dot instead of Red Empty Green dot instead of Red

I got a Holson green dot on a trade a while back and really didn’t pay it any attention.

Put it on a pistol I was working on just to run to the range and try it out.
Suddenly, the dot was round, not the starburst I’m accustomed to with the red and my astigmatism.

Girlfriend shot it a few mags and announced, I want this on my pistol......
So I ordered another one and have put it on the new to me 208 and will see how it goes.

She has had it on her pistol for a couple of club matches and says she will never go back to red.

Anyone else tried a green dot?

I actually prefer green for most situations.  However, there are reasons why you may prefer red.  Here's an interesting article on the subject.

A friend of mine swears his green dot sights are round while his red dot sights have a comet tail because of his astigmatism.  My astigmatism causes both to look the same, with the comet tail.

I have one sight with both red and green.  The red contrasts better with the black for me.   

A lower setting and bigger dot all make it round for me.  

I use a 5 moa or 8 moa so its just visible.    

I was taught to make the dot so I can just see the target through it.  

I have guns with red laser and green laser. The green is more visible in the daytime by far.  It also uses more battery.

Eyes see green better. Although it isn't brighter than red, the eyes perceive it so. Red is also harder still for over 40 eyes to see. Aircraft instrument lights used to be red and the lights in ready room were red. The reasoning was that it preserved night vision. Nowadays, modern aircraft instrument lights are a pale greenish color. They work very well. Being way over 40, I prefer green to red.

I've been wondering about that for a while now: no one wants a laser light flashed to the eyes because of potential permanent damage.
Ask any star wars fan : the coherent beam is much more efficient at destroying stuff than regular light.

Yet, a red dot is nothing but a laser pointed straight at your most sensitive fovea centralis on which your eye focuses it as much as it can. I understand the light intensity is kept in a safe range. I've been using red dots for only a couple years now and still use the same setting.
Here is my question: do older shooters have to increase the brightness of their dot so as to compensate for [HYPOTHESIS : cones killed by their very optic]?

And to stay on topic, a green laser has a shorter wavelength than a red one and each photon packs more energy therefore has a greater damage potential on the retina.

For what it's worth, I'm 77 and haven't had to increase any red dot intensity so far.  I adjust intensity solely because of lighting conditions such as bright sunny days vs overcast days.  Indoor range conditions may also require an adjustment.

I don't think that's an accurate statement. The light source in a conventional red dot sight is a simple LED (light emitting diode), and when shooting you're viewing it as a reflection on a piece of glass. A red dot sight is certainly not a laser.

A laser pointing device, "Crimson Trace" e.g., is a laser, but it's not pointing at your eye. It's directed at the target, and your eye sees the portion of the light reflected back.

You are right, thank you for the clarification.
