Working through Aimpoint and Astigmatism

[Hmac]

That does not help when you have astigmatism in one or both eyes. Shooting 8" plates at 100 or a 12" plates at 300 sucks with astigmatism, you need to focus to place the dot over the plate.

The red dot is projected on the same plane as the target. That's the point where it will be at the best focus distance-vision that your eye can achieve. If you are trying to focus on the dot instead of the target, you'll be frustrated.

I have 20/15 vision otherwise, so I'm not sure that I am a candidate for vision correction surgery.

Everyone if different. I can focus all day long on the target and will still see either a dash, comma or star burst in either eye. If I squint real hard looking at the target sometimes it will become a dot.

I understand where you are coming from but it does not work for everyone.

Actually it does help. I have strong astigmatism in both eyes and focusing on target strongly reduce flare/comet on red dot. Also flare/comet effect seem to be much less in natural light, than it is indoors with artificial light. Getting bigger dot (for eg. 4MOA version instead of 2MOA) helps and setting brightness lower helps a lot as well.

I agree using the 4moa T-1 and turning it down does help. But focusing only on the target does not work for everyone me included.

Focusing on target does not remove problem. It just reduces it. Together with larger dot and lower brightness it can almost nullify it.

Same problem and also the basis for my name BTW. I run an Eotech and Aimpoint. I have had my eyes checked annually and I do not have an astigmatism. I wear contacts when I shoot. I only have the problem in low light. Sometimes the Eotech reticle will double and offset slightly. It helps when I focus on the target more but more light is my solution. With a weapon light it goes away. Daylight I have no problem.
It is just one of those things that you need to work through and around through practice.

I don't know how far forward the T1 is on the upper receiver, but I found a location closer to where the rear sight is located that gave me the best dot resolution. You might experiment with relocating the sight and see if that makes a difference.

My Aimpoint M2 is mounted further forward, than my T1.

Whatever works, I guess. But that just doesn't make sense from an optical standpoint unless you are trying to focus on the dot instead of the target.

Best thing to do it to NOT strain.. Place the optic as close to the eye as is practical, keep the intensity low, focus on the target and don't strain.. I have some serious astigmatism even after cataract surgery and Torx lens replacement. This is what works best for me.. Cheers.. Ron

Is an Eotech less prone to this? With a 1MOA dot, it could be pretty explosive/starburst/tail-having, I would think?
