As a young m/cyclist I thought to have a small tinted strip across the top of my visor to allow me to dip my head fractionally to reduce the suns glare directly into my eyes should I round a corner and find it blinding me.. While driving in Italy through the many tunnels and then emerging into direct sunlight I found it handy to have "flip up" sunglasses over my driving glasses, which could be flipped up and down in an instant as necessary..

With no sun visors or want of them in my Mog, those old flip up sunglasses still work reasonably well.... Which reminds me I should get round to replacing them with a new pair, but they seem not to be as readily available as they once were..
