My first post - bear with me!

Mike,

I think that beauty in landscape as also a time, in the sense of

"moment in time" affected thing. You are sensitive to the same

landscape giving different emotional response at diferent times.

I don't think that there is necessarily one response to a particular

scape, it\s a matter of how we are feeling at the time (as well as

lots of other variables....

my 2p. Tthanks for the fascinating thread.

Hi Leonard,

As a optometrist working in Low vsion this also appeared initially

confusing. However there is light at the end of the tunnel as it

were...!

Your problems in comprehsion are to do with "exit vergence"

from the magnifier .Let me (try to..)explain.

If you look at the exshenbach web site you will see exit vegences

listed. These are the vergences for each magnfier expressed in

mm.

if you have an exit vergance of 250mm (4D) then you will require

a spectacle powere of +4D to see through the mag clearly and

comfortably and be using it at it's optimal magnificatioon and

field of view. OR you need to be myopic yourself by 4 dioptres OR

have enough focussing ability (ie under 40) to be able to focus by

4 dioptres comfortably.

If you are pseudophakic (ie have had cataract removals) then all

this depends on your post op refraction...

Clear as mud?

e- mail me off list of you want to know more.....!!
