I bought these glasses thinking they will be good for driving at night. However these are gradient lenses with red tint at the top and yellow at the bottom. So the top half of the glass is too dark for night driving. The red tint isn't dark enough that to be worn during the day either.<br /><br />EDIT: Forgot to mention... it did NOT come with the US Flag cover that is shown in the oicture. It came with a regular black cloth cover.
