I'm about to venture in to this uncharted (for me) territory of purchasing eyeglasses online. I'm tempted to try a pair of rimless - which would also be a first for me - but a little nervous about the edge thickness of the lens.
In my current glasses which came from a brick & mortar shop, the left lens (-2.50 spherical, -1.50 cylindrical, & 160 axis) is about 53mm wide & 27mm tall. At its outer-most edge, the lens is 6mm thick. I have no idea what the lens index is specifically, although I recall at the time of purchase, that I had to pay a bit extra and wait a couple of days for "High Index" lens. I'm comfortable with a comparable lens width (+/- a couple of mms) but I worry that in a rimless style, that's 6mm outer edge would look kinda bad. So, would stepping up to a more expensive 1.591 or 1.60 High Index lens keep that outer edge thickness down a bit? And aside from the cost, is there a downside to using a higher index lens - do you forgo some material strength or scratch-resistance when you get into those higher index options? I read something that implied that higher index lens might be less optically-correct than standard index lens - any truth to that? (I've never had half-rimless glasses either, so I guess the same question kinda applies for those, since I would imagine that the bottom left edge of the lens is going to be fairly obvious with a half- rim design - although maybe not quite as jarring as it'd be with a fully-rimless lens.) And finally & more generally, I'm a new Dad and my glasses are taking a bit more incidental abuse from my rough & tumble toddler. With that in mind, am I just crazy for even considering rimless? Would a hinge- less design be better or worse for enduring minor bumps? --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://glassyeyes.blogspot.com!
