For those experienced with RDS's, I've got my first one, an Insight MRDS for my USC. I notice the shape of the dot varies at times. Sometimes I look at it and the dot is nice
single circle, sometimes 2 slightly overlapping circle, definitely 3 overlapping circles when I wear my prescription lenses. Is this normal? Is it just my eyes or could their be something defective with the sight? Thanks for your help.

I get the same thing. its Astigmatism in the eye that causes it. go outside in the light and let your eyes adjust and check it out. it will probably look like a circle again.

Thank's for the info. Yes I do have some astigmatism. For a while. I was a little concerned with RDS. I spent so much on it. thank you again

Yup it totally happens to me too. My friends think Im nuts- esp. when I told them I see like 5 dots in a connected curved line. Cant use Aimpoints. I do OK with the giant EO tech reticle, but I try to stick to irons and ACOG's.

If you look at it through an aperture, it will usually correct itself. I use an aperture (or magnifier) for long range shots to get rid of the effect of the astigmatism.

A lot of people don't even know they have an Astigmatism until they use a red-dot sight and get blurred or misshapen dots. It's not uncommon though, something like the Leupold Prismatic with the 1x etched retical can be a big help in stuff like that though.

Bingo on the astigmatism. My friend has issues with it, especially with the dots on the Eotechs. To me I don't see them blobbing out.

You haven't lived until you watch a "floater" the size of an aircraft carrier drift over and settle in the middle of your sighting eye. A blink or two and it's off to the side a bit... but still threatening to creep over the center of the eyeball.

I worry tremendously about this. I'm told I'm at high risk for retinal detachment and to go to the doc immediately if I start seeing fireworks in my eyes. Very scary stuff as I don't like dogs that much.

I use a Leupold Prismatic and love it. My astigmatism is too annoying with RDs if I am not wearing glasses.

Oh, come on. Doggies are fun. Wanna see my "woofer"?

Quite common if you focus on the dot. But realize with a RDS you should have both eyes open and focus on the target. Then the dot will seem the proper shape.
