I have inexpensive vision insurance and am allowed to get one pair of glasses/year. A few years after my lasix, I found out I could even get non-prescription sunglasses under my insurance (I wish I'd realized that earlier!). So, I get a nice pair every year. I have a frame I really like, so I just get a new set with different lenses each time (a pair for foggy days, a pair for sunny days, a pair for afternoon light, etc).
One year, I caved and bought Maui Jims. My insurance did not completely cover those... But, they are awesome! I can't see my phone screen with them like I can with the others (the others are also polarized, but different), but they are amazing. Sometimes, after working a lot of overtime, it's ok to treat yourself :)
There is something on the back of one of my eyes that worries the optometrist (said if I was older he would think it was macular degeneration), so I pretty much always wear them when I'm outside.
I have a few cheap, drug store, polarized glasses that I keep on hand as well (for outdoor work), but I tend to lose those. Somehow I've never lost the good ones (very thankful for that).
