See well when driving – protect yourself from blinding

Eyesight correction has to be the best possible in traffic for your own and others' safety's sake, so that you see road signs and other traffic participants at the right time. Check the strength of your driving glasses regularly.  You may often need spectacles of a different strength for night driving. Make sure the frame is strong and fits well. For safety's sake it is worth having a reserve pair of spectacles.

Being blinded can be avoided by using sunglasses.The shade of photochromic lenses changes according to UV-radiation – but the darkening will not occur in a car as the window shields do not let the UV-radiation through. Polaroid lenses help avoid the reflections from water or road surface.
