" Did a drive to and from Llanberis on Friday last week. About 6 1/2 hours driving and approximately 5 hours in the dark. Very comfortable.
I would have doubted my visual comfort over and above my usual Varilux X4D's if it wasn't for my 3 passengers exclaiming when I had those brighter headlights coming towards me.
I was fine - I could tell the lights were brighter and little uncomfortable compared to "standard" lights, but I was never "blinded" and was much more comfortable than my passengers.
Would I put them on for a short journey in daylight instead of my Varilux X4D Transitions XTRActive's? I usually wouldn't make the effort for that.
Do I put them on to drive at night? Every time.
The only snag is that they are so comfortable to wear that I often forget and get several paces from the car before realising I need to swap back to my Varilux X4D's. "
