had one tonight,looked left,right and left again, turned right out of my road and straight into the path of a totally unlit car coming straight into my side wing, I just managed to stop 6 ft into the road,when I became of a black shadow to my right, she swerved around me, and the male passenger gave me every sign under the sun.
Now who would have been most culpable if there had been a collision

A Doctor friend of mine once told me that while he was training he made a particular study of the functions of the eye. At one time he held ambitions of becoming an opthalmic surgeon.
The thing this thread has reminded me of and which has stuck in my mind for years is a scary correllation he told me about. Apparently those who would normally wear glasses or contact lenses for driving ( provided they wear them ) show little difference in their daytime visual skills over those who do not need glasses. In other words the corrective lenses work very well in daylight. However, these people often have noticeably poorer night vision than those who do not need glasses or contacts. Alarmingly, the vision ability difference between night and daytime driving is much more marked for that sector of the population.
As he pointed out, this throws up a whole new set of problems. In poor light, one group ( the spec free ) are still seeing quite well, the spectacle wearers however, are not.
Driving is still punctuated by misjudgements on a sight level playing field. Little wonder that darker nights bring more woe if there is a sudden widening of the variances in vision abilities. The fully sighted could well be assuming that they, or a given situation are entirely visible when in fact to some, it, or they, are not.

Absolutely true, Humph. I am perfectly legal to drive without glasses (reading a number plate at 25 yards in good light). When it is dull - or worse dark - driving without them is scary...

HB, MM, IIRC it is called night miopia, I have it, on a bright clear day my eyes are virtually perfect though as the light level lowers they worsen hence I wear glasses for driving and hence I need prescription sunglasses because they, of course have the effect of lowering the light levels.

Upon re-reading HB's post I realise that you are talking about sumit else !

Fairly worrying, when you think about it, that although one driver might be able to clearly see what is going on that a fellow user of the same stretch of road may not. A timely reminder never to assume I guess.

wotspur, for the second time, "Stop looking on the black (dark!) side."
