We tinted all the windows in our home, including the northern windows, with a greyish tint, the best available at the time in Comfortplus glass (8 years ago). We bitterly regret as we have to turn the lights on too much in winter, and the tinting is woefully inadequate in summer. "Clear tint" is now available and would probably be much better.
Can't really comment on glare from winter sun... we are surrounded by trees (on neighbours properties) which is brilliant in summer but not in winter... but in summer we found the only thing that worked is fully retractable cotton canvas awnings. Of course external louvre awnings would also work on clerestory windows.
