I use a company called OneStopGlasses
About £20 for a pair delivered to your door, same with prescription sunglasses.
They also do frames with a one piece “Comfort Bridge” which is what I prefer.

Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
