I recently bought a vortex venom to go on my 870 youth 20 gauge build. Mounted with sumtoy mount. I didn't know that if you have an astigmatism that the red dot would be star burst or odd shaped. It's not horrible but its definitely not round and clear like it should be. Anyone else have this issue? Also for those with a venom does your dog look perfectly round even on the lowest setting? Thanks for anuly replies.
i have them in both eyes and have used a FF3 for 5 years with no issue at all. thats the first I have even heard of that to be honest.
Yea I thought it sounded odd but Google it and you'll see others have same issue. A test u can do to see if it's your eyes or the sight is hold sight in hand and rotate in a circle looking at red dot. If the starburst or weird shaped dot stays the same and doesn't spin as you spin it it's your eyes. If the shape of the dot does spin it's the sight. It's not horrible but it sure isn't a perfect circle dot. It has a weird shape

crazy Ive never heard of that but I guess you learn something new every day lol. I figure its worse for some depending on how bad you eyes are. Ive never noticed it but then again maybe I just always figured it was suppose to look that way :)
Google it and watch some videos. It a depends on how bad your eyes are. My dot is odd shaped and when I turn the sight it stays the same and the shape doesn't turn with sight. If it turned with sight it would be the sight. I know I have a astigmatism as I were contacts and eye dr has always told me I had it. I love scopes with the circle and crosshairs. On my 12 gauge I have Leopold with turkey plex 1-4×20 but on my youth 20 I wanted to keep weight down so I went with vortex venom. Love the sight and weight and the shape of dot isn't to bad so I'm gonna go with it.
It's very common even for people who do not need glasses. Take a look through a Trijicon RMR and a Leupold DeltaPoint. Those two are the only ones that do not star burst for me.
I'm gonna roll with it. Also just read that polarized glasses will make the dot appear clear and round even with astigmasisms. Gonna try it tomorrow. I'll let yall know the outcome.
Well the polarized glasses work with astigmasisms. Whe. I put the glasses on the dot is super clear and crisp with no crazy shape or starburst. As soon as I pull them down the dot starburst and is shaped weird. Guess I'll be wearing glasses some.
That's really interesting about the polarized lenses. I had the same issue with the red dot. Started with the 8 MOA and when the astigmatism got worse went to the 3 MOA. Finally settled on prescription shooting glasses with an anti-reflection coating. The prescription corrects for the astigmatism to and I enjoy the sharper vision when trying to spot gobblers coming in.
Yea I wear contacts and are for astigmatism but still get starburst. With my costa sunglasses the red dot is perfect
Very interesting read. I also have an astigmatism problem, I don't totally understand it but have always been told mine is severe though I don't honestly know why. I know I have had at least 3 surgeries on my eyes when I was young that I remember but have been told I had 5 surgeries on them. I know part of them was to fix being cross eyed on both sides but other than that don't know much about the others. I remember having to have one of my lenses on my glasses blocked off to help the other eye.
I was thinking I would like to get a scope for next year, so I guess I will stay away from red dot scopes. I want to find one of those Nikon scopes with the turkey reticle I think.
I had the nikon btr scope but it was too heavy for me. I have a Leopold 1-4×20 with Turkey plex and it was much lighter but nothing compares to these reflex sights other than open sights for weight

Hopefully I can find one to lay hands on, I am a Nikon fan to be honest and have several scopes from them and would like to stay with them if I can.
I have it in my right eye and not my left so I can see a difference between the two I'm used to it for my right eye now but if it's sunny and I wear polarized sunglasses it helps.

I have mild astig, never noticed anything? there are different degrees, if you have it bad it might be a problem i imagine. Your eye doc might be able to help you. Mike
I had that problem with my vortex . did not have it with the aimpoint micro . changed the battery in the vortex and it went away
I never thought about polarized sunglasses but wearing them does eliminate the starburst when looking through the ff3. I could be wrong but I don't think the starburst is caused by an astigmatism. Blurry or misshapen dots may be, but I think the starburst is caused solely by the glass. Impurities in the glass scatter some of the light from the LED giving you a starburst. I have an ff3 and a Vortex Razor Red Dot. I get the starburst when looking through the ff3, nothing but a crystal clear dot when looking through the Razor. The main difference between the two is the quality of the glass.

Yes. That's moderate and on astigmatism for you! I use contacts and then have a slight magnification Bc I'm old. Makes all those dots DOTS again.

No need to stay away from red dot. I swear by em! Talk to ur eye doc and he or she can set u up.

I can tell you astigmatism will make you see crazy things. With my contacts in for astigmatism and my near sightedness the dot is pretty round and clear add polarized lenses and it's perfect. Take contacts out and I see about 12 dots and starburst like crazy.

I made an appointment for Sept. to get them checked out and get new lenses, I have to get two pair, one for close up and one for driving with a bifocal in case I have to sign a ticket or something. (Not that a good little boy like me would ever get such a thing) lol I will talk with her then about it.
Yes, I have Keratoconus which is astigmatism on steroids. I wear special contacts for it and still get star bursts (Halo) effect and slight double vision with red dots. I have gone to scopes on all my turkey guns and was told to try a prism scope red dot to see if that would work. I wear polarized sun glasses nearly every time I'm hunting or outside for that matters as my eyes are light sensitive with the disease. I still notice the effects with glasses on. I run etched glass reticle scope that has a light built in if needed.
Had a fastfire 3. Did exact same thing. Returned it in 1/2 day. Switched to an eotech and have zero problems.
