Seriously, are these "troll" posts just to fill up the Forum. If not, why not take the 5 seconds to Google this question? Sorry if I sound annoyed, but just seems ridiculous that people cannot look this stuff up themselves:

LogMAR chart - Wikipedia

Of course, I googled this. I cannot use Wikipedia as a reference to my scientific research. I need reference information that all people accept it. When I googled I found generally Snellen explanation and some personal explanation of LogMAR.

I am not sure if LogMAR has a standard;

Google "logmar-eye-test-charts healthcare". I cannot post a link directly because I am new here. it is a restriction of this forum.

in that page, except distance, there are few variations of LogMAR.

I am an engineer and I am not familar with medical reference databases. I asked my question here to get a better answer than Google.
