what happens when the batery runs out mid drive and the glare hits you while you are trying to change lanes at speed?
i reckon i will stick to my simple polarised raybans. just something about overcomplicating a very simple solution just for the sake of it doesnt sit right.
Most modern battery powered devices give a warning when the battery is getting low. This could, too. How about a cable that plugs into the lighter outlet, as your phone charger does? Then it never runs out.
I've done a lot of east-west driving, and no conventional sunglasses work well in direct, low-elevation sunlight. If they are strong enough to keep the sunlight from hurting, you can't see the road well enough.
