| Some manufacturers of good polarized sunglasses add rubberized earpieces to their products to prevent slippage in rough, wet conditions. If your sunglasses don’t have them, or, like mine, the rubber wore off, fix the problem with marine-grade heat-shrink tubing. Simply slide a piece of heat-shrink over the end of each earpiece and heat them so they stay put.- Kirk Daggett, Wellington, Florida |
