I few years ago on this site someone posted a video taken within a racing Corvette on track. Open visor, bird to windshield, smashed windshield, first thing driver did was reached to his eyes with both hands. Needless to say, shattered glass in eyes.
A few years ago I had cataract surgery on one eye, everything went perfect. A couple years later I had cataract surgery on the other eye. First couple days after everything was tracking same as first eye. Third day after surgery I became blind in the eye. I could visually see light concrete and dark grass. Couldn't view someone's cloths, face or any other color differences. Had to wait 3 months for two specific surgeon's to be available on same date for further surgery. I'm here to tell YOU ALL who drive with open visors close them before something happens. It was not easy to keep my mind in the correct place for 3 months when I had vision in only one eye. Holly $hit thoughts of only having one eye and thinking about loosing vision in the one good eye. End result after the second surgery, everything returned to normal.
