Night Driving

I attended an outdoor art exhibit tonight, and went to it wearing my sunglasses.  It ended after dark, and when I started driving home, I realized I was having some difficulty seeing.  I was extra cautious driving home, and arrived safely.  In the back of my mind, I was thinking I might have to be very judicious about my night driving in the future. When I pulled into my garage, I realized that the reason I was having problems with vision was because, although it was dark, I was wearing my sunglasses.  Hopefully, in the near future at least, I will not have these night driving problems again.
