Comments on rimless glasses

[womens eyeglasses]

Hello there,
In my notion that I need to pay more attention in choosing a rimless glasses than other designs as I have decided to buy a rimless glass and as a result I need some help please.
1) Based on your experience, which seller provides the strongest
rimless glasses?
2) What kind of glasses material should I choose for rimless? I want
to have a strong pair.
3) Should I get a titanium based one, or other material is just fine?
I have problems just in one eye (-0.5) so I want to use the money
wisely in a rimless glass.
Thanks all.
