I've been wearing glasses since third grade. Until ten years ago I refused to wear them much and chose contacts instead because of the thickness of my lenses. In conventional framed glasses, my lenses stick out from the front and back of the frame. At the time I first got my rimless "frames" my prescription was -6.5. My belief is that with rimless, my lenses may be thick but the benefit is that the lenses become the "frame" and therefore there is no goofy appearance of the lenses sticking out. Let's face it, higher power corrections are coke bottle bottoms! They are thick yes, and heavy, but I LOVE them. Go for it, but understand you may never like the thickness of your lenses, but the rimless does help minimize the embarrassment of that coke bottle bottom look, you're just not drawing as much attention to them as you would with a conventional frame. Hope this helps :)
