Best site for quality high-index lenses

[discount eyeglasses]

I always wear”coke-bottle” lenses, and my optometrist suggested me to change them for high-index lenses, I have a really strong prescription, my left eye is -8.25, and -9.25 for the right one, I know these kinds of high index lenses, but I have no idea where can I buy quality ones, you know that nowadays there are many sharp-shooters, and what’s more, these lenses are always very expensive, I don’t want to waste money on fake ones, anyone can tell me which is the most trustworthy online shop for high-index lenses?
