Hello Alecchong
I was very interested in your post re the Dk/t values and lens thickness. Clearly these are very relevant to the informed reader/lens wearer who may wish to screen different lenses before trying (subject to medical fitting).
However, not all manufacturers quote Dk values (though the generic Dk value can usually be obtained with knowledge of the lens material) and very few seem to quote Dk/t values. Lens centre thickness is also very seldom quoted.
Have you got a link as to where this info is posted or do you have to contact the manufacturers directly, etc?
Thanks
