I bought RX glasses direct from Tifosi. Prompt service and the price was good. I also bought Tifosi glasses from SportRX but returned them because the prescription didn't look right. They said the glasses didn't go through QC and are remaking them. Their price was about $100 more than direct from Tifosi.
I recently had cataract surgery on both eyes and my vision improved but I still have astigmatism enough that seeing close (numbers on my bike computer) is a little blurry with single vision lens. SportRX says progressive lens would not be possible with curved lens I want. I'm learning to live with the blurry numbers which are better the brighter the light is.
