Are there any tools online for giving a rough idea how thick glasses\nlenses will be at their thickest point given the prescription, size of\nlens and lens type? I've ordered some 1.67 thinnest lenses online and\nthese are much thicker a pair from an almost identical prescription with\nnormal 1.57 thickness I ordered from the same place a year ago (as they\nwere just meant to be temporary!). I do admit the lenses in my latest\npair are widerr, but at the point where the others would have stopped\n(from the middle out) they are about the same.\n\nI've always gone for high index and am used to what size they roughly\nend out at, but to me these don't look right. This was as part of an\norder of 2 pairs (along with a reading pair with a +1.00 Add) and they\nare insisting the distance pair are correct from the one email they've\nresponded to. Now they seem to be refusing to answer my emails!
