On the contrary friend! Driving into the sun's glare without proper sunglasses greatly accelerates the process of vision disorders commonly associated with aging - specifically cateracts. In fact, people tend to develop this condition in their age because of the cumulative effects of those brief moments. An unprotected viewing of a solar event (eclipse partial or total) simply multiplies the damaging effects exponentially. Further, light of that brightness tends to "burn" the retina; so far, I don;t believe there is a laser surgery to correct that!
