I recommend contact lenses! I only wear my glasses around the house and put my contacts in if driving or riding. It’s just another layer to reflect glare in front of you, not to mention it gives you severe tunnel vision. No more flicking your eyes to see whats to the side of you.
On my first helmet I purchased a dark tinted cellophane strip that attached to the top of my visor that worked pretty well. When riding into direct sunlight I just had to tilt my head so I was looking through the tinted section. Unfortunately it wouldn’t stick to my Arai visor due to the vents in the visor. I like the sound of the internal sun shades that raise and lower but they are only available on a few helmets. Not worth buying a new helmet over but if you are in the market it would be worth looking at I think.
Yeah, I guess it doesn’t rain much in AZ and when it does the roads are probably really greasy. I can see just avoiding it would be an option there. I’ve read on forums some folks who ride into work in the sunshine then freak out when they have to ride home in the rain. That I think is silly and potentially dangerous.
