These lasted a good 2 months but now the coating seems to have scrubbed away enough that they're stressful (feel like what it would whilst riding in the rain) to wear. My mind was made ages ago that they needed to go, but another month managed out of em (eye protection from branches and maybe midges/flies and other stuff.
Don't want owt expesnive but not so cheap that they'll become blurry in a short time! Any suggestions for some economical specs that won't cause heart disease if misplaced/lost...

Thanks and sorry for the big blurb!
