The comments are very interesting. I think glasses are a very specific issue. The question is: do want perfect view or just want to see something better.

For better view this is great.

But for the developed world it is not comparable. Either because the eyeglass frame should follow some trend, or the glasses itself needs some additional threatment.

For example, my glasses are 'cheap' even as I need special glasses. Yes, the diopter are different between left and right. But much more important is the parallax compensation for me. My optician exchanges the glasses even for free, if they don't fit. So online, is realy not an option.
