I forgot to mention an issue that has cropped up on longer rides. I’ve worn contacts since my twenties. I went through some issues, but finally got a perscription that works and have had them for quite a few years. I take them out at night, but have noticed that if I leave them in, they get really dry.
So I’ve noticed that my focus deteriorates on longer rides. I wear protective glasses, and don’t feel any discomfort other than trying to squint to read a sign or what-not.
Could this be that the wind is drying out my lenses, or could the exercise possibly be reshaping my cornea temporarily? I guess I should try taking some eye drops along next time.
Anyone else having this problem?
