Rifle Scopes Question about blurred sight via scope

[Bloodstriker]

I had a strange occurrence happen at the range today. I was looking through my scope and for short periods of time, everything would get blurry. It didn't look like mirage but more like when a scope isn't focused at all. This would last for 10-20 seconds at a time.

Could this be dust or smoke from other shooters messing with my vision?

Yes, could be dust or smoke, but usually obvious to me when that occurs.

 

[Bloodstriker]

I know what you mean. It didn't look like dust or smoke.

I should also add that I don't experience this problem during dry fire practice out my window.

Were you looking through the glass for long periods of time? Eye fatigue can cause your eyes to do strange things, like temporarily unfocus. Also, if you were focussing rapidly on objects in very different focal planes, your eyes can lag behind your brain a bit in focussing on the new object. But, it could have been smoke or dust.

I would say it started happening after 1.5 hours.

I'm not sure bust smoke/dust is distinct in that it looks grainy. This was just blurring.

I've seen that lots of times. Smoke (even small amounts) and dust raised by neighboring shooters blowing past the front is too close to be focused in most scopes, and appear as a blurry fog. Now, if there was no fogginess, just blur like a mirage, it could have been crap floating across your cornea. Did blinking change anything?

Don't forget to focus your reticle at least twice a year. Us old guys maybe even more often! CKruse

Nope. Blinking didn't help. Maybe it was crap from other shooters.

Funny you should say that. I'm refocusing my reticle as I'm typing. I'm pointing at the sky and strangely, it seems all but the very extreme end is very clear...

 

[ckruse]

Hope that helps. Remember to get an unobstructed view (or your eye will focus on the item in your view) take a quick look, focus, relax your eyes and do it again. I've found that lots of folks just don't take time, or have the place to just step out and do it while they are thinking about it. Good luck! CKruse

Were you shooting as well? If so it could of been the heat off of your barrel causing the blured effect
