Sorry to blunder in like Colonel Blink (the short sighted gink) but, speaking of specs, what do those with prescription lenses recommend?
I'm currently using an old pair of my regular specs which are ok but I do get a bit of a blind spot (blurred spot actually) looking back over my shoulder to check traffic etc. I'm a relatively mild, short-sighted prescription.
Are the "insert" type specs worth trying and, if so, what's the deal with the lenses? Are they a standard fit that can be bought at an opticians or do you need prescription inserts specific to the brand of eyewear you're buying?
