I've been riding at night for years, so far my vision is still good, even at night. Riding at night is for sure different. I like riding at night because it takes me to another level of alertness. I stay focused and on edge, constantly scanning, trying to be ready for anything. What I hate about night riding is a cager that doesn't know how to turn off their high beams, this takes the ride to another alert level. Anyway over the years I've to get much enjoyment from this whole experience.
