I didn't start wearing sunglasses until I was around 34 yrs. old. About 2 yrs. after I returned to cycling regularily. Amazing that I used to think sunglasses would darken my world unsafely or whatever nonsense.

Now I find my eyes sensitive to outdoor daylight that whenever I bike or go for walk, I must wear sunglasses. And this is not even it's sunny. It could be cloudy.

I often wonder about the plastic lens part for UV protection, how much protection it is really providiing. If anyone has good reliable info...

I also prefer my lens colour to be more grey netural instead of yellow or a slight off-pink which makes gives scenery a more blue tone. I'm quite picky about fit and the sunglass arm also because I wear sunglasses for cycling. They must fit around eye, to protect bugs or dirt that flying in or little stones bounce up. The arms must be slim and shaped in a way that when I wear a ear protection headhead over my hair and them, that they don't press against my head to hard.
