Coming home the other evening, the sun was for a change extremely bright and even with my darkest sunglasses on, it was still a little un-nerving heading west from the low sun dazzle, and as I live by the west coast I usually finish up heading west to get home. I also find the LED lights dazzle even more in the plain un-tinted windscreens fitted to a Morgan when its not always sensible to wear sunglasses.
Has anyone any experience of having tinted the entire front screen and whether it helped at all at dusk and driving at night? I appreciate there are legal limits of light penetration in the UK. Just wondered has anyone tinted their entire front screen

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.

Just to be clear, the yellow tinted night driving glasses don't help with the low sun issue! I was only suggesting them for the LED headlight glare - I keep a light, wire framed, pair in each car to put on over my prescription specs at night. For the low sun issue, baseball cap is fine, but a wide-brimmed hat a bit better as you can tilt it to one side or the other to deal with the sun shining in at an angle - only problem is having to ignore the "yeee-haa" taunts from pedestrians, or tolerating "where are the dangling corks, Aussie"!!
