I am trying to make an effort to wear sunglasses whenever I'm outside, and I've noticed two main times I need sunglasses that have different requirements: Driving and Beach. Beach: Full coverage to block stray light Need something either cheap to replace, durable, or with a good warranty Driving: Good peripheral vision Mainly the need for full coverage at the beach (which would suggest something like Costa) conflicts with the need for good peripheral vision when driving. If I get dedicated glasses for each activity: Fishing sunglasses for beach, with good coverage. Costa (good warranty?) or Berkley from Walmart (cheap). Rimless, wire frame, or aviator sunglasses for driving. Good peripheral vision but less coverage and more fragile. Costa, Maui Jim, Oakley, Suncloud all make models that could work. Downside, requires switching when I get in/out of car. One pair for both: Wraparound like Oakley, Wiley, or Under Armour that has good coverage but doesn't block peripheral vision. Downside, I don't want to look like a soccer coach or mall ninja. Does anyone switch glasses when driving? Or use one pair for everything?
