I always want when i order progressive lenses (especially plus) to give them a paper sheet with all the specific details. But sometimes i receive the lenses and i cannot insert in frames because they give me a smaller lens (-1 or 2 mm).I want to ask haw to give them measurements with an addition of 2 mm in every direction, but I came up with a problem:
exemple:
lens width:53mm
lens height:35mm
Bridge width:20mm
DP OD:33mm
DP OS:33mm
Fitting height:23mm
To receive a bigger lens add +4mm on the lens width, +4 on the lens height, and +2 to the Fitting height
MY question is that: do i modify the bridge or dp?
Thank you!
