Blue blocker (orange beige colored) polorized glasses work well for me . They enhance color, minimize glare and add contrast. Sometimes there is no avoiding sun blindness. 2 days ago someone almost T boned me because they could not see the traffic light due to afternoon sun low in sky this winter season and chose not to stop but they did slow down honking as if they had the right of way on red.
I drive defensively and imagine every tenth driver is intoxicated or challenged.
