Are you left eye or right eye dominated ? Or you're like me .
I do not have a pronounced domination for either left nor the right eye. If I need to blink a few times and try to determine which eye is more dominant then, it's my right eye since I'm right handed.
However, I was a lefty when I was very young so was my brother, been conformed to the righty after going through the preschool and kindergarten. Back then there were more pressure on being conformed to the crowd,
So if I have the peep hole closer to my head then it'll be left eye seeing through the hole . Right eye if I stretched arms to the limit, but once in awhile I will confuse myself switching back to the left eye.
My eye-hand coordination is better then the average and I could focus on the hair on the back of a fly when I was young. Still am the one finds partners golf balls on the golf course often enough. Maybe that's why they love to play with me.
