Today was one of the stranger days I’ve had biking. 
Somehow I managed to leave the house today without my contacts in! I’m very nearsighted too. No contacts, no glasses = I can’t see much past the nose on my face.
You might wonder how this happened.
Several months ago I switched to daily contacts where I toss them at the end of the day and put a new pair in the next morning. Some days I don’t bother, like when I’m reading or doing computer work like today because my reading/computer vision is best with no correction. Or other times I just wear my glasses.
I always wear glasses or contacts when driving – and until today when cycling.
When I realized I wasn’t wearing my contacts, not wanting to take the time to go home and get them, (didn’t think it would be a problem) I just pedaled on. Of course I should have gone back because not surprisingly I had trouble seeing once I was actually riding – not cars, I could see those fine, but watching for cracks in pavement, potholes, etc., especially in the shadows, was very difficult.
And when you can’t see well it slows you down, screws with your balance, gives you a headache from eye strain and makes your bike quit shifting!
Okay the last thing is unrelated, but it did happen and provided just another sign to call it a day.
So after covering half the distance of my planned ride I heeded those signs and turned around and headed back.
I felt like Mr. Magoo on a bike.
