Myht Vision No one can seeas well at night,as in the daytime. Butas we get older-these differences increase. A. 50-year-ald driver may require least twiceas .at much lightto see the same thing at night as a 20-year-old. What you 80in the daytime can also &ct your night vision. For example, if you spen-d-the in bright sunshine day you are wise to wear sunglasses.Your eyes w l have less trouble i l adjusting to night. But if you're driving, don't wear sunglasses at night. They maycut down on glare from headlights, but they also make a lot of things invisible that should r.enminvisible-such as parked cars, obstacles, pedestrians,or even trains blocking railwaycrossings..You may want to put on your sunglasses after you have pulledinto a brightly lighted service or refreshment area. Eyes shielded from that glare may adjust more quicklyto darkness back on the road, But be sure to remove your sunglasses beforeyou .leavethe service area. You can be temporarily blinded by approaching lights.It can take a second or two, or even several seconds, for your eyes to readjust to the dark. When you are faced with severe glare (as from a driver who doesn't lowerthe high beams, or a vehiclewith misaimed headlights), slow down a little. Avoid -staringdirectly into the approaching lights. If there is a line opposing of traffic, make occasional glances the over l n of headlights to make certainthat ie one of the vehicles isn't starting to move into your lane. Once you .are past the bright lights,give your eyes time to readjust before resuming speed. High Beams If the vehicle approaching-you its has high beams on, signal by fliclcingyours to high and then back to low beam. This is the usual signalto lower the headlight beams. zf.the other driver still beams, resist the doesn't lower the ternaptation to.put your high beams on. This only makes twoha-blinded drivers. On a freeway, use your high beams only in remote axeas whereyou won't impair approaching drivers.In some p€aces, like cities, using high beams is illegal. When you follow another vehicleon a freeway or highway, uselow beams. True, most vehicles have day-night now mirrors that enable the driver to reduce glare. But outside mirrors are not of this type and high beams from behind can bother the driver ahead.
