I usually just buy the cheapie aviator style sunglasses available at Walmart/Walgreen's/gas stations/wherever. When I used to travel a lot for work, I would almost always forget to take sunglasses with me ... just didn't think to grab them out of my car when arriving at the airport at 0dark:30. Get to my destination, and squint getting off the plane. First stop with the rental car was nearest gas station or drug store to pick up cheap sunglasses (try getting that ZZ Top song out of your head now!). I had quite a collection of them from California, Montana, Utah, Colorado, Missouri, Illinois, Michigan, Texas, Indiana, Tennessee, Virginia, Maryland, and New Jersey. :confused2: Most of them would end up collecting in my vehicle or motorcycle trunk as spares. Those aviator style are also the most comfortable under a motorcycle helmet, at least to me anyway. I still keep a pair in both my car and my bike.
Around the house, though, I've been using the Allen shooting glasses from
MidwayUSA. Had the same set for the last five or six years, and use them for shooting and working around the property. The rubber is just now starting to tear on the frames over the ears, so I'll replace them with the same.
