That's a great point! If you are older than 30...or shoot at places other than well-lit 10-meter ranges...IMHO an adjustable-opening iris is a must-have accessory for any target rifle. OEM diiopter-sight eyepieces typically have an opening around 1.0mm which can be tough for other environments.
Gehmann, Centra, and AHG make a vast range of irises, and they can be had with any combination of color filters, a polarizer, and a 1.5x magnifying lens. But the simple variable opening models are economical, smoothly dial in any opening from 0.8 to 3.0mm, and make a huge difference. All these old sights made since the 50's use the same eyepiece mounting thread, too, so a single iris fits them all.
Here's an older Gehmann iris, in an Anschutz sight, on a Weihrauch HW 55.

I have an adjustable Gehmann on my 300s, but find it more difficult to see through. I’ve dialed it both ways and although I can see the target getting brighter, the clarity of the target is horrible. Maybe I’m overlooking something in the setup of this sight.

You have an older unit there, maybe the magnification function lens is fogged from age? This seems to be common with the even older Seibert/Hensoldt types, and if you carefully clean it, maybe better performance?

D75 by a landslide !!!
It ( the 75 ) is a Full size rifle, Large target grip, unreal trigger, full length anchute rail, adjustable butt pad ... an Honest full feature match tool.
Rebuilt several W55's and while they shoot well enough, there by build structure / size no where close to the diana. Use a more typical stock profile, there a lot smaller being more 3/4 size to the 75's. Trigger is good, but no 75 trigger !!!

I have two 75s. Beautiful and superbly accurate. My wife and I shoot them several times a week. Both recently service by David Slade a master mechanic.

As specie said, checking / cleaning the lens is always a good idea! I'd also note that newer units have a bigger lens with a better focus range than these older ones.
When I first got one of these magnifying irises, I found myself actually relying too much on the lens. The iris opening is the primary means of optimizing depth-of-field; then go back and forth with the lens to tweak that, and adjust things to your eye. If you use too big an iris opening, you won't be able to see the front sight and target both clearly.
Also, the lens cannot compensate for some eye problems such as cataracts or extreme astigmatism, though Gehmann makes some (spectacularly pricey!) units that will fix the latter. If you wear glasses but don't have extreme issues, you may actually be able see through the lens better without your glasses - that's what I'm doing these days.
The old sights came with the big rubber cup eyeshades - but most modern match shooters do not use those. The contrast between the tiny, super-bright sight picture and surrounding blackness is fatiguing to the eye.

MY problem is not seeing the sights , it is seeing that "all gray" sheet of paper that up closer has 24 individual bulls on it !

I have the Gehman on my 75, I had the same problem with older eyes and used the magnifier in the front sight and made the target clear.

That’s exactly what my problem was! After specie talked about possibly cleaning the lens, I started looking closer at the sight. I then discovered that the silver collar pictured below is actually a focus wheel….DOH!!!! Shows my limited experience with the diopter sights. After focusing, WOW!!! What a difference!!! Crystal clear. Amazing setup

Ha - that's great! I'm glad you're enjoying it.
Again, don't neglect to also play with the iris opening size, that's your depth-of-field adjuster. The lens is basically the icing on that cake, LOL.

Many Thanks to everyone who shared their experience. I am buying the 75 and sending it to David Slade. It will be the only 10 meter gun I own.
I collect concentric air pistols.
Again thank you for helping

Don't limit your fun to 10 meters with iron sights. Scope it and stretch it out. These guns have a lot of potential that will not be realized with irons at 10 meters.
