Over the last year I’ve found these yellow anti-glare glasses to be invaluable. I use them in daylight as well as at night, they’re especially good in dull light, rain and mist. OK, I’m in England so that’s pretty much all the time, really. If you are recovering from eye surgery or have a cataract then I can highly recommend them.
These polarising sunglasses are rather good too, although they don’t get nearly as much use. 😉
