Can I get rimless glasses with +3.0 (farsighted/ hyperopia) prescription?!
Question:
Can I get rimless glasses with +3.0 (farsighted/ hyperopia) prescription?
I was at my local Lenscrafters today, and the guy said that with a R.E. +2.50 and L.E. +3.00 I should not get rimless as they would look really bad. He explained that the middle of the lens would look extremely bulky.
I had my hopes set on rimless glasses and I am adamant to get them.
I've done a bit of research tonight and found that apparently high index lenses reduce the thickness of farsighted lenses as well. He offered me "featherweights", but from what I read those are regular polycarbonates, not high index lenses.
Armed with this knowledge should I go back and challenge him, or is my prescription too extreme to get rimless frames without them looking bad? I always under the impression that my prescription was mild compared to others...
If you can help me I'd really appreciate it. Thanks in advance.

If high index lenses are too brittle, why does Essilor recommend their Thin&Light 1.60, 1.67 and 1.74 high-index lenses specifically for rimless frames?

I don't mean to be confrontational or anything, I'm just trying to sift through some of the conflicting information.

Answers:
"+" lenses are thinnest at the edge, so to get sufficient thickness at the edge to supprt rimless lens mounts, they have to be made deliberately thicker.
Most high index materials are appreciable more brittle than conventional plastic (CR39) lenses and even that is is not very satisfactory then lenses are thin. Polycarbonate lenses are distinctly tougher.
I would suggest looking for a a very thin metal-rimmed frame.
The overall effect will be much "lighter" in actual weight and in appearance.
With + lenses, the roundest shape of lens *that suits you* will give the lightest, thinnest, best-looking lenses. Avoid square shapes. This is a geometry thing, not a fashion one. The lenses "bulge" on the straight edges with rectangular shapes.
The smallest lenses *that suit you* will also give the thinnest lightest glasses.
