As an optician in my previous working life, I would strongly recommend against wearing any tinted lens when driving at night. Even so called night driving glasses absorb too much light to be considered safe. The yellow tinted lenses absorb strongly in the yellow sodium wavelengths produced by many street lights. In some countries even driving at night with clear un-coated lenses would be illegal, as without an anti-reflection coating not enough light is passed through the lens but reflected away from each surface. Most of us above a "certain age" will find low sun an issue. The lenses inside our eyes get more misty as the years pass and although not enough to be classified as a cataract it is enough to frustrate focussing in direct light, much as a dirty window in direct sun. As others have mentioned a peaked hat along with good sunglasses prescription or non prescription will help. Polarizing tints are particularly helpful with reflected glare given off bonnets and road surfaces, though these can be problematic with toughened windscreens and some digital screens. There's no easy answer but there are also some effective prescription driving lenses around, with practically clear lenses they are designed for all-day use.
