These are great sunglasses to use on those bright sunny days. I have an issue with one of my eyes that required several surgeries and the result leaves my right eye with an undialating pupil. I need to wear sunglasses on virtually all days. I love the when driving as they are crystal clear. These glasses are almost to dark at the end of the day,  however. I usually switch to another pair at that point.  Overall they are great for thwe price.
