Just realised we might be talking at cross purposes. Do you mean you bought the Rydon frames and had lenses mounted into them locally? Or did you buy a cheap frame and have Rydon lenses fitted into them?
I recently got a pair of the new Madison Enigma glasses - they are their take on a big wrap around frame. Really liking them, especially as being Madison they are great value, but decent kit.
Previously I had been riding Oakley Sutro’s, which are an almost perfect riding pair of Sunglasses IMO but silly expensive at well over 100 quid.
The Madisons are £24.99 for a pair, or £49 for a pair with 3 different lenses which is what I went for.
Been riding with the Pink Orange lenses which offer a pretty much perfect lense for all round riding, good in the sun and good in the trees.
They are super comfy with a good adjustable nose piece, big enough to offer a clear field of view and protect the eyes, but no so big as to interfere with your helmet.
Highly recommended, especially as Madison offer a compressive supply of spare parts if you damage them.
