A while ago I posted a topic discussing cycling specs options for people with strong corrective prescriptions. The point was reached where I had found something on the Bolle website about a new product called B-thinactive, but was trying to see them in the flesh.
Anyway, I found an optician with a good relationship with Bolle, and they arranged a meeting between them, the Bolle rep and myself. I went down this morning and we spent an hour rifling through a four-foot tall case full of samples.
Long story short, the B-thinactive thing is amazing. They can get close to -10.0 prescription, so mine at -6.5 plus -1.25 astigmatism is easy. They are still really light as well. Apparently, the innovation isn't the hardware, the clever bit is a software algorithm that engineers the lens by taking the curved blank lens and machining the optics to provide corrective vision for a normal coverage area on the lens, but then tapering down to no prescription on the edges (ie the wraparound bit). It's weird. A standard index lens in my prescription would be 20mm thick at a wraparound edge, which obviously isn't practical. This stuff comes out at 6 or 7mm on the edge for me. You can't see a distorted area on the lens either. (I checked for you Cat1commuter!)
There's a big choice of frames, lenses, colours etc, but I'm looking at the Helix design, which is the white/orange pair on the site referenced above. A high-contrast brown-base lens seemed to work best for me, with either black or grey frames. Polycarbonate with anti-glare, no polarisation or photochromic finish, looking at £254. I'm just waiting on a grey frame sample before ordering.
I still might fancy polarisation, but at an extra £130, it's not just an impulse add-on, so I'm having a think first. Do anyone else have any opinion on the value of polarised lenses?
