Sunglasses with magnifying bit

[Dave Davenport]

I wear glasses for reading and am starting to struggle to read the map when touring. I saw these and thought they looked like just what I need, but would have to order them direct from the US.

Has anyone tried them?

No, but look interesting! My wife has just got some cheap fashion bifocal sunnies off Ebay which are the same in concept. To be honest, when road cycling I do not need to use reading glasses. But just off on a long tour and will take them in handlebar bag just in case
