Get Yourself Some Cheap Sunglasses - ZZ Top
B.A.S.S Black frame wrap around.... Polarized
I get them when they go on sale at a local sports store..... about 12-14 bucks.
I get a new pair each spring to start off the season, they can take the abuse, and end up in the glove box in the late fall as a back-up.
Last time I bought a "Spendy" pair of shades, they ended up in 2 pieces after being sat on at a party, $89.- gone with the wind, phftt!
If you gotta fu...dge with your specs. or constantly worry about pinnin them back...
Thats less time fishin, and spendy ones scratch just like cheap ones....
