A couple of years ago I was about to go with aceandtate, ended up going with specsavers because they had a thing where you'd get sunglasses with prescription lenses too for free when you bought the normal ones. If you nab some promotion like this it's really good value. Ended up being under €150 total for both pairs (1 normal, 1 sunglasses), and this is with max durable lenses and I'm blind enough that my lenses are also not the cheapest cause they're too fat for that. Was the cheapest acceptable ones I found and they have some that look as trendy as the A&T ones.
