I can only speak for Zenni versus the local opticians I used before. I had tried enough different lens materials to rule out CR39 and crown glass due to disfiguringly thick lenses (about -6 sph, -4 cyl in my weak eye) and to rule out polycarbonate because of the bothersomely compromised vision it gave me. I had settled on 1.7 index glass and plastic whose optics were only acceptable but which made nice thin lenses. My first order from Zenni was a memory Ti frame with 1.67 plastic lenses, but as an afterthought I added a pair of plastic frame sunglasses with Zenni's base "mid index" plastic. I had half assumed this would be some flavor of polycarbonate, but I discovered to my pleasant surprise that whatever material it is makes decently thin lenses with hands down the best optical clarity I've had in many years. My high-index glasses from Zenni are at least as good as what I had been buying from my eye doctor, but the regular no-extra-charge lenses are much better, without being too terribly thick. I'm still unaware of any common or proprietary lens material with the claimed 1.57 refractive index of Zenni's base offering, so I can't even speculate as to what exact material it is... but I give it a wholehearted thumbs up.
