Antiglare Visors?

Same junk marketing as the night vision glasses. Driving glasses of optical quality should help. The problem with polarized is that it may filter out the screen on the GPS or tablet.

A good pair of polarized driving glasses may be a better choice. I used them for years while driving a delivery van. The visor does work but just a caution... Neighbor bought one and did not fold it up when he exited vehicle. The next time he got in he hit his head on it and ended up with 4 stitches.

Wife wanted one so I got it from Amazon. I don't often use it but it helps after you get used to using it and the yellow color. She doesn't like it because she said it makes everything blurry. I tried looking at it from both sides but did not have that problem. Cheap enough to try.
