Dear Otis,

I  also use an as simple as possible language when I want to explain matters
in the "eye field" to laymen to avoid wrong conclusions and at the same time
I can have a conversation  thinking a simple language using person could be
very intelligent at the same time.
BTW you do not use the extension "eye" as you did when you speak of "OD"
eye, "OD" have the "eye" already in the expression.
OD= Oculi Dexter where "oculi" stands for "eye", the same goes for OS which
stands for Oculi Sinister. (I used capitals to clarify)
And Otis, why should I use my professional terms when I can explain things
better in simple language.
The language then must be as accurate as possible off course and that's the
point where we disagree.
I'll try to explain or translate the stuff from an eyecareprofessional
background as I am used to daily.
You try to created your own definitions from an other background and in that
way misinform some people here and I'll think that's real obscure.
And to Jeremy I shall explain where Otis did not, Otis did take the wrong
numbers to explain your possible vision acuity and for reasons I do not know
he did not correct his mistake.
