I stopped buying expensive sunglasses 2-3 years ago. Now I buy safety glasses for $7.00 or so a pop. Look good and when I'm working around our place I've got eye protection. Now I started bicycling about 3 months ago: bought a Giant OCR1 and a Blackburn Neuro 6.0 cyclometer. The Blackburn is great but there is one field in the display that is pretty small for my farsighted 62 year-old eyes. Bought a pair of gray safety glasses with 2.0 diopter inserts! Especially when cycling you don't even know the inserts are there unless you look down. Not only can I read the very small numbers in the upper right-hand corner, but the whole display is easier to read - don't have to take your eyes of the road for but an instant.
