In Germany, I bought mine from lensbest Not sure if they are high quality. When I compared sites a few years ago, they were the cheapest I am really troubled with the cylinder for my astigmatism. Many sites only sell glasses with 2.5 cylinder. Lensbest sold 3 diopter cylinders. The eye scanner at the optometrist said I need a 3.75 diopter cylinder. Although the optometrist said, I still get full vision with 3 diopter. I wanted to buy cylinder-only glasses for computer work. Because my normal glasses also have spherical component against nearsightedness, but the screen is near enough that I can see everything without that and the correction is only causing eyestrain. But I cannot buy them. The cylinder is too high for the sites, and the local optician said I do not need such glasses
