Is it harmful to wear non-prescription sunglasses over prescription contact lenses?

My morning commute is 45 minutes heading directly into the sun. Since I have very sensitive eyes, I was hoping to get some sunglasses. Thing is, I love the freedom my contact lenses provide me and after heading into my workplace, I do not wish to put in my contact lenses and once again remove them and put on my prescription sunglasses when I need to head out. So, the question is: Is it safe to wear non-prescription sunglasses over my prescription contact lenses?Thanks in advance to anyone who can help!
