Before I potentially waste a few quid...............

Personally I cannot see how severely restricting your binocular vision is an aid when shooting live animals. Depth perception, binocular summation and field of view are lost or massively hampered even with a parallax adjusted monocular vision.

More to the point, train yourself to shoot with both eyes open whether with irons, red dot or magnified scope.

If I shoot with both eyes open I get less eye strain, if that makes sense.

Indeed. Especially when behind the rifle, on aim for extended periods waiting for target exposure / waiting for target to settle etc

I initially thought of getting the straight eye piece as in the posted pictures but then thought after reading further posts, to try without the specs on so I have bought both the angled and straight ones for the grand sum of 4 quid delivered
I'll see how they both compare and if there is any advantage to not having the specs on.

Plus both eyes open gives better situational awareness
