Does water on an open dot sight affect it?

[gersus]

I tried the search but couldn't find anything. I've never used an optic on a shotgun so I'm wondering how dew or water would affect it? The last thing I want is to put on an optic and have to be careful with my gun.

I don't know about the rest of the country but around here often the grass is soaking wet from heavy dew and I sometimes have to crawl or lie in it to get a shot.

Thanks for the help!

I think most of them are waterproof but that's a controversial topic on it's own.  Claiming to be waterproof has many different meanings.   Waterproof does not necessarily mean submersible.

I look at "waterproof" as being not ruined by being subjected to water seeping inside. What I'm wanting to know is if a drop of water is on the lense, does it make it difficult or impossible to make the shot?

Thanks for replying!

That should not be an issue.

Thank you for answering. I truly appreciate involvement of manufacturers on these forums.
