I have any number of pairs of cheapy Aldi or Lidl sports glasses for work, they do the job just about. my problem is that I have sat on, dropped, left behind, lost, etc. more pairs of sunglasses than I care to remember on the bus, so I only use cheapies nowadays.
However, for my outside work life, I have a pair of Rayban aviators my wife bought for my birthday many years ago, I also have some Oakley Flak 2.0 XL with several different lenses and sleeves for my differing moods. I also bought recently from someone another pair of Ray bans and also a pair of oakleys.
Current favourite lens is my photochromic ones as they can adapt to the strength of the sun.
I've had two pair of the oakley flaks, the arms broke on the first pair. I do abuse them but love them to bits. First pair were about £150.00 second pair about £98.00. I wear contacts so they help with sensitive eyes. The main thing though they suit my round face.
Polarised glasses are good for fishermen, but for driving and most other things you ought to use ordinary sun glasses so that you can see instruments correctly.
For instance with polarised a sat nav will just be black ( true you might be able to make it out with difficulty) l have tried to put a link on to explain better but with my phone it might not work.
