It really is a guessing game when it comes to deciding whether to take along my dark lenses or my vermilion lenses to work.

One morning a week or so ago, it was overcast at 7 am; in fact, it was drizzling. The forecast I had checked the previous evening said it would still be overcast by late afternoon.

When the sky is clouded over, dark lenses can easily be too dark; so I took along my vermilion lenses. Lo and behold, the sun came out! It was not very comfortable riding home with the sun shining in my eyes, and I wished I had my dark sunglasses with me.

The next day, it was overcast in the morning; but the forecast said it would clear up during the day. I took along my dark sunglasses. On the way home I kept getting the sun full in my face, and having dark glasses really wasn\’t much help. Sometimes you just can\’t win.

I need to get me a pair of 3M Smart Lens sunglasses, though. Automatically-adjusting tint would be helpful. I wouldn\’t have to carry along an extra pair of sunglasses for long rides that are apt to see changing conditions. Nor would I need to stop to switch glasses when it goes, let\’s say, from overcast to bright sunlight.

There\’s usually a certain degree of guessing game for long rides, anyhow. Maybe so things will stay interesting?
