I often drive long distances, in this optics I checked my eyesight for free by appointment (very convenient without queuing), I was advised to use prescription seiko lenses specifically for drivers, the difference with ordinary ones is huge, they darken in bright sun, remove glare from the headlights of oncoming cars, and visibility is much better, eyes do not get tired at all. The guys are really experts in their field, they select the most suitable lenses for different needs, not just diopters, but functional ones. In general, I didn't even know before that there are different lenses for glasses. The glasses didn't sit very comfortably, I didn't notice right away, I drove in, everything was fixed and cleaned quickly and for free. Good luck to you, you are doing a good deed.
