I have always had trouble with glare when driving at night  due to severe astigmatism and then a bit worse after lasix surgery. I happened to stumble upon these when looking for a pair of sunglasses so decided to order a pair.
Since moving to a mountainous rural area of an island (no reflectors on roads, poor or non functioning lighting, heavy downpours ect...) driving at night had almost been eliminated for me; and when I did dive at night it was always a very stressful white knuckle experience.  I can't not express how helpful these glasses are! They have made such  difference and eliminated almost all of the glare from headlights and glare from wet roadways so that I can now drive much more relaxed at night.
