i am fed up of having mud thrown in my eyes on a steep descent and having to go down one eye shut. i want to get some glasses around the £25 or less mark, preferably with changeable lenses but not essential. any advice/reccomendation??
many thanks simon

Check out this thread, Should point you in roughly in the right direction.

I've got a pair of DHB glasses from Wiggle, 3 lenses, grey, blue and clear all for under £25. I use these rather than my M frames as i don't mind breaking or losing them.

ye they seem allright good value too.

i got some DHBs from wiggle
can't work out how to change the lenses!!!

can anyone help?
