This sounds really ridiculous as I type it, but I've taken to driving
in
the dark wearing my prescription sunglasses. Even then I flick my
eyes from side to side to avoid the same piece of retina going to
sleep.

It could be because I only passed my test two years ago, but every
time I fill up with petrol when it's dark I walk around the car and
check
all the lights. I passed my test two years and one week ago, so I'm
no longer a probationary driver, so maybe I'll start getting slack and
lazy now.

Tinted specs used to be marketed as night driving glasses, but they
are not a good idea.
I don't even use the "dimming" feature of my rear view mirror.
I can switch it off on my current car, on previous ones I have
resorted to blue-tack to blind the sensor.

The danger is (eg) that cyclist in black with no lights, that is
undertaking you as you turn left. Without the tint (glasses and/or
mirror) you might just see him, with the tint he might disappear
beneath the threshold where you might have seen him.

There is an argument that you can dispense with dipped headlights and
everyone drives with polarised full beam-headlights.
The drivers wear polarised spectacles with a 90 degree relative
polarisation, or better still have a windscreen made to that
prescription.
Now you can even turn off all the street lighting (topical!)

This is not a new idea, I first came across it as a child in a book by
J.B.S Haldene published in 1948, and the idea was not new then.
