Re: Which prescription bi-focal polarized sun-glasses?
Polaroid sunglasses are extremely expensive; and like killer pricie. If you've already got good prescription bi's consider a set of Cocoon over glasses/sun glasses. Cost forty bucks and really are a hell of a good product.
One of the things I really like about them (above and beyond the price) is the wide ear pieces next to your eyes. Really do a good job of shutting our side glare.
