Few users really expend the effort to actually quantify what causes results.

In a post months ago we all were greatly benefited from your measures of exit pupil ilumination profile of 3 premium binoculars.

Variable subjective opinions require objective testing.

If few people bother to quantify by perception the color differences of the different solutions exposed above, even less to measure it in quantitative and qualitative data. Just by testing is possible to determine if a precise measure of the spectrum delivered by different areas of exit pupil could prove if a ED design is better than stopped one (or other solutions already mentioned). As already stated there are different glasses for use in ED merchandized lenses, so if a quality non ED is better than ordinary ED is just subject to testing.

I don't know about the instruments and method to do this.
