For the last few weeks, I've been noticing what I see when I swim. I have noticed two things about my free stroke.
1. When I do free, I see almost my entire left arm stroke. I breath to my left. I see my hand enter the water, begin the catch, pull to my waist. Then it disappears. I see it then when I roll to breathe. I only see my right hand briefly as it enters into the water. I think this might be because I don't rotate my hips enogh as I pull my right hand & arm through the stroke. Then it reappears as it passes my waist and relaxes.
I swam some laps breathing to my right and i saw exactly the opposite.
2. As I begin to flip, I look down, seee my left big toe, then my eyes move to the right foot. As my feet pass over my head I look through the space between my right big toe & the next toe. I was really amazed at how much I can see outside of the pool through this gap. As I roll I close my eyes to blink. Then I look at the left side of the pool for the push off and pull out. I realized that I do this even when I am not thinking about it or consciously looking.

Why would clear goggles (as opposed to any other color) do this? What wizardry is this?
Perhaps it has something to do with pupil dialation. When you wear dark goggles, your pupils are more dialated. With clear goggles, the pupils are more constricted. The constricted pupils make smaller apertures which give a greater depth of field for focus. Photography people are familiar with this aperture effect in cameras.
