The side windows are so fuzzy/scratched they're basically useless, and definitely not to be trusted. You have to tilt your head and look around the frames when changing lanes. Other than this fatal defect/flaw, they're great. They fit over my glasses perfectly and easily and are comfortable. I especially appreciate the top to bottom gradient, which not only provides a more ideal view looking straight ahead, but allows you to adjust the level of alteration and target sources of glare by simply tilting your head. I'll see if I can polish the side windows with something, but maybe I'll have to take a chance buying this type of product again from another source, because the concept and design really works great.
