ParaGunner Posted February 27, 2019 Share Posted February 27, 2019 Just got a holosun 510c green dot sight and the dot looks terrible. It's not a solid dot, but it looks like multiple little uneven dots. Can't figure out what is wrong with it? Do I have a bad one? Link to comment Share on other sites More sharing options...
dcs12345 Posted February 27, 2019 Share Posted February 27, 2019 What all other red dot optics do you have? Are the dots perfectly round on them? Link to comment Share on other sites More sharing options...
racknrider Posted February 27, 2019 Share Posted February 27, 2019 Do you have an astigmatism? i do and my dots look like crescent moons. Look at it through the camera on your phone and see if it becomes a round dot. Link to comment Share on other sites More sharing options...
ParaGunner Posted February 27, 2019 Author Share Posted February 27, 2019 I have a vortex venom and the dot looks perfect and I don't have astigmatism. Link to comment Share on other sites More sharing options...
hiker88 Posted February 27, 2019 Share Posted February 27, 2019 Sounds like you might have astigmatism. As racknrider said above, take a picture of the dot. If it’s crisp in the pic, then that confirms your astigmatism. In my case, a larger dot from 6 moa and bigger is crisp. Anything smaller is a star burst.

Looks clear in picture. My 6moa is crystal clear, the 2 moa on the holosun is blurred. Thanks for diagnosing. Link to comment Share on other sites More sharing options...

Steve RA Posted February 27, 2019 Share Posted February 27, 2019 You could also check with an eye Doctor. Link to comment Share on other sites More sharing options...

She checked my eyes and said I had an ever so slight astigmatism. I took a picture of the dot and it is indeed perfectly round. I told her about how it looks to my naked eye which is squiggly looking starburst. She says other things can cause it as well since my astigmatism shouldn’t be bad enough. So like I said. Put the dot or blob, whatever you see, on target and shoot Link to comment Share on other sites More sharing options...

pjb45 Posted October 4, 2021 Share Posted October 4, 2021 I have both: astigmatism and 510C-green. I wear contacts with no correction for the astigmatism Love the 510C. It is on my JP PCC. In the AZ sun the green shows up great. Recently, at the PCC match it was very cloudy and the brightness overwhelmed my ability to see the plates. I had to turned it down and the world was right again. The adjustments are good on the 510C. I have DPP on my CO guns which is nice but when Santa comes I might switch to the Holosun for my CO. I really like the circle dot for shooting steel. Link to comment Share on other sites More sharing options...
RaylanGivens Posted October 5, 2021 Share Posted October 5, 2021 I have noticed that my two 510c dots occasionally have the star burst look... I have tried to figure out what was wrong and this thread finally cleared it up for me... It never occurred to me that it might be my eyes... Taking a picture of my dot showed a perfectly round dot... It seems to get worse if I enlarge the dot. I have never heard my eye doctor mention that I have astigmatism... Is this something that could be corrected with glasses? I wonder if it's something Brian could correct with Hunter HD Gold lenses? Link to comment Share on other sites More sharing options...

Is this something that could be corrected with glasses? I wonder if it's something Brian could correct with Hunter HD Gold lenses? I have astigmatism and use two different sets of glasses for shooting irons and red dots. For irons, I had my eye doctor give me a prescription where I can see the front sight clearly. When I use this pair of glasses on my red dot, I see a star burst. For red dots, my pair of glasses made for long distance gives me a crisp round dot. I’m not sure though if this true for everyone.
