In photos with Ko Ping-chung and Ko Pin-yi I see that they don't have their cue under any specific eye, mostly directly under the chin. Is this "Ambi-ocular"?
Could mean anything. I'm not sure how to diagnose if you're ambiocular, but to find your dominate eye focus on something 15 feet away with both eyes, then by closing 1 eye at a time, find the eye that doesn't make the object jump to the side (that's your dominate eye).
Focusing is obviously more important. I'm trying to find some sort of optical aid that I know I need, but ever test measures that I'm just fine. It seems like under certain light conditions things are noticeably blurrier, but I can't replicate that light to prove it in office, so I'm not sure what to do.
However I know something is up with me, as just about any bar box pool table light causes this blurry effect (3500k to 4000k), or at least I'm perceiving it that way. I know when the light is coming off of 10 feet ceilings (commercial ~5k environments), I never notice this and have no problem focusing on my shots. With research in attempt to help explain my condition, I've discovered that warm light is not good for focusing (as seen with auto-focusing cameras), and red light causes weird fractal artifacts (as seen in a green houses), so at this point I'm left to assume that anything but ~4500k to 5500k is not fair conditions for most games/sports requiring vision (which I guess makes since as all events target ~5k it seems).
NOTE: I only brought up the whole light temperature thing because when I shoot on a bar box, I have to adjust my posture to focus better, which could be what Ko is doing (for which ever reason, although it's probably just for comfort).
