I-78 facing west at 6 pm today in central NJ.
Sun glare sucks. Around the winter/spring and summer/fall season changes, it's pretty bad as the sun is getting lower in the sky - and sunset is right around rush hour. Normally, it's not an issue with me since I don't get off work until 8, and sun glare heading westbound towards home is really only an issue in June. But when you have the extra traffic of rush hour and you crest a curve only to come face to face with a huge fireball, you need to be able to negotiate the road and the traffic safely.
Sun visors block the sun, but not the glare and reflection off the vehicles in front of you (or your hood and dashboard). Which means, a quality pair of sunglasses. Here's a good explanation of polarized vs non-polarized sunglasses and how they affect your forward vision. Another web article on what to look for in sunglasses addresses tints, shapes, and other available features.
If you wear prescription glasses, a quality pair of clip-on or wraparound/"fit-over" sunglasses may serve you better than prescription shades in that when ambient lighting changes, you don't have to worry about finding another pair of glasses while you drive... just flip up or take off the shades and you can see just as clearly with your normal corrective glasses.
And remember, your inability to see in low-sun conditions affects everyone around you - don't be the cause of the next bulletin on the radio traffic report because you couldn't tell how the road curved ahead of you or that the vehicle in front of you is slowing down.
