FWIW - I bring both regular and sun glasses (both Rx) with me anytime I go out and wear the pair best suited for the day. I have a hardshell case to protect the pair I am not wearing from damage, which pretty much eliminated accidental breakage in the pack. I do tend to like the eye protection they afford from tree branches, insects, and other surprises that can find their way into an eye along with the reduction of reflected UV they provide.
If you need them , then by all means use them. Who cares what others do?
I would put it this way: if your skin out is more than 20 likely yes - less than 20, other things would be higher priority
i have transitions lenses on my glasses. LOVE them. its like sunglasses that come on automatically.

Alough they don't need to be dark sunglasses or set tint lenses it might be nice to have eye wear/sunglasses to keep the gnats from committing eye suicide.
I bring sunglasses. They double as spare prescription glasses, without which I'm blind as the proverbial bat. I have smashed my glasses in a fall before.
I always know where I am. I'm right here.
As much as possible, I try to keep UV light out of my eyes. This means I always wear a visor and UV-proof lenses.
This is because I have two goals concerning cataract surgery:
1) I want to live long enough to need it. ALL HUMANS will either get cataracts as they age, or they will die. The only thing you can control to slow down the former is your ocular exposure to UV radiation.
2) I want to wait till I'm in my 80s before I have it. Yes, intellectually I know it's very routine & quick surgery, but the thought of eye surgery gives me the willies. I don't even like my daily eye drops, but I know I need them.
I don't wear sunglasses, as glare doesn't bother me. But I MUST keep UV light out of my eyes.
According to a recent NYT outdoor article you need $300 sunglasses if you're consuming "gourmet" trail food.
I wear glasses full time. Did not like the switching back and forth from reg to sunglasses so bought some transissions (sp?). They change well except for bright sun on new snow!
