Ok, the first thing I'm going to say is, at best I'm a novice when it comes to rifle scope tech talk, so bear with me here.
The term Optic Ring I got off the website "Optic Thoughts". Thanks Ilya! Am I correct is saying it's the black ring around the object you are looking at through the scope?
Why do some scopes have a very thin ocular ring, where the image seems to go right to the edge of the scope? While the ocular ring on other scopes is so wide it looks like your viewing the target through a tunnel?
What causes a ocular ring on a scope to be thin or very thick?
What scope brand or type are known for the thinnest ocular ring?

How about cloudiness or scope haze, what causes it?
Why does scope haze seem to get worse when you turn the magnification up in a scope?
Thanks

The size of the eye box is a function of design. I am not a tech writer so that can be left to others. Haze is from defects in the glass and coating systems that are employed. Cheaper glass more defects. Magnification magnifies the defects and the glare. Anti-reflective coatings reduce glare and haze. Better glass and better coatings cost much more. This is why better glass trumps higher magnification every time. This is the short version.

This may help with the terminology.

It sounds if you are discussing quality to me. And the certain compromises that every manufactures have to make in order to complete an optic. There is no such thing as a perfect scope. I also have read a lot of ILya's writings. And the one thing that has stuck is that when shopping for a rifle scope is for me to pick the compromises that are the least bothersome to me.
 
 As far as the thinnest ocular ring that I have ever encountered on a rifle scope was hands down the 4-16x56 Hensoldt. It was like looking through a bubble.
 

The haze and cloudiness is for the most part, a lack of quality lens coatings. After all, magnification can't help but magnify imperfections in the lenses. Hope this helps.
