Red/Green dot sights and people with astigmatisms

I agree with GExpat. If I am distance sighting,I pop up the BUIS and the dot becomes defined. At close up range,it doesn't matter if it is a blob. I do this on my AR and Ruger PCC.

My eye doctor told me mine were ready at my last exam. The left one is already gone and the other will leave next week.

I have astigmatism. I have an easier time picking out a red dot on any color background than a green dot.
I figure the color preference will be determined by what the shooter's eyes can see easier. Not sure why astigmatism alone would factor into the color of the dot?
Regarding dots being clear or broken into "grape clusters" or simply just blurry, I've always been able to fix that with a new prescription of glasses. Provided that the dot in the sight hasn't gone weird.

Oddly enough, even with glasses and an astigmatism, the green laser is more visible than the red ones for me. The green is even more visible (to me) in bright sunlight.

I'm near sighted, far sighted, and have an astigmatism, I prefer red over green on my sights, and greens for my targets especially outdoors. I also shoot best with no correction, sights or targets. I paid a bunch of money to a sports optometrist who only made ****e worse. Considering lazer surgery.

So you have anisometropia and astigmatism (by the way, all of you, it is just astigmatism, not "an astigmatism", or "astigmatisms"), but need no correction for shooting? o_O

Glad you found a good Dr., doubleh.

For those getting near that time, do your research; both on Opthalmologists, and IOL's (InterOcular implants), there are many options.
Here's a good place to start:

I have a problem with blurry dots. I have ordered a Vortex Spitfire 1x. It is a prism scope that serves pretty much the same purpose as a red dot. I’ll post my initial observations once I get my hands on it and zero it in. I have read it is great for people with astigmatism.
 
I had cataract surgery and I now have positive disphotopsia, ghosting and starbursts. I think the Dr just wanted corneal knowledge of my bank account. I think shooting is going to be a long time gone. It's been 2 months since the surgery. Maybe it will get better. I will go back if it does not.
 
+1 on the prism sight.

My wife has pretty severe astigmatism, she can't stand red dots, but likes prism sights quite a bit. They're making some nice 1x ones now.

I had my first one removed 1 week after getting the news it was time to do so. For those considering cataract surgery I would like to say that it is painless but follow up is a bit fiddly with having to add all those eyedrops regularly. I oped for distant visions and readers for close-up work. My vision in that eye is now sharp as a tack past about three feet. I'm basing that on sitting here and reading the print clearly on this forum on a 23" monitor. The world has also become a brighter place and colors a bit different also.
 
I have pretty bad astigmatism among other vision issues, shooting my revolvers without glasses (so I can at least see both the sights and the target) I have vertical double vision even with only one eye open. (I figured out I just have to use the "ghost" version of the front sight, which was counterintuitive, I assumed the more solid-looking one was the "real" one.) When I got my AR I got a holosun red dot, no good for me, I could only see the dot in uniform bright light, i.e. not if either I or target (or both) is in a dimmer area. Also I had an artifact when shooting off the left shoulder, a wiggly vertical red line above but not touching the dot. Got an aimpoint and I love it, I can always see the dot right away, regardless of the environment, and no weird artifacts. It does get a bit starry if I turn up the brightness but I got the AR for home defense and that's the distance I practice at so that doesn't matter.

Thank you for your response, the attempts to make me glasses have not worked. I can either see the sights or the target, never both. Without glasses both are fuzzy but better than the alternate of poor glasses.Thank you for the link will investigate!

That's generally typical, you generally have to 'sweep' through you optical depth of field,--rear sight, fore sight, target. That is until the targets are very close.

I've always had asymmetrical myopia (±20/30 OS; ±20/40 OD) with some astigmatism. Just with decent acuity despite that. (So, no seeing a 1 inch grid at 100yds, but a 1" checkerboard is fine.)

Since bilateral cataract surgery, distant acuity has increased, but uncorrected astigmatism is some worse (OD hovers around 20/50; OS has gone to upper 20/30s--but that's reading text). Since cataract surgery, what's frustrating is needing magnification to read scope graduations (or text on the phone, for that matter).

As to dots, I find the green dots more comfortable to the eyes, but reds easier to adjust. Go figure. YMMV
 
I have both an astigmatism and am colorblind. Red dot (6 MOA) slides to a pretty big starburst under the right light and when I'm not wearing my sunglasses.

But bright sunlight makes the red dot disappear almost completely (even on full Power).

Green Dot shows up better, doesn't seem to vanish in sunlight, at least in the few I've tried, don't own one yet.

The circle and dot on my EOTEC doesn't give me any trouble in any light or with/without my glasses. Not sure how it's different but I much prefer it and stick to irons for my pistols.
 
I’ve changed all my FO front sights to green and have one green dot and four red dot and I find the green dot easier to see in virtually every circumstance.

Che k out this article it explains how the human eye sees a broader range of the green frequency than red. The reason red dots became the standard was that generating a red dot requires less energy and therefore your battery lasts longer. Now technology has caught up and generating a green dot does not disproportionately use up your battery. All my future sights will be green dot. https://www.pewpewtactical.com/red-dots-vs-green-dots/
