Knowing your dominant eye is important for all sports—and no different than whether you are right- or left-handed, you are right- or left-eye dominant. But, even if you are right-handed, it doesn’t necessarily mean that you are right-eyed.
It only takes a quick test to determine which eye is your dominant eye. Simply bring your hands together in front of you, and bring your thumbs and pointer fingers together to make a small hole between your hands. Bring your hands up to your nose. Find an object or a spot on the wall and focus on that spot through the hole you have made with your hands. Then close one eye at a time—the eye that finds the spot is your dominant eye.
Knowing your dominant eye can help give you an edge when you play sports, regardless of which sport you are playing or what your skill level is.
For example, if you hit a golf ball, you should always position your dominant eye directly over the back tip of the ball when you line up to putt. This straightens your alignment, and gives your putt a greater, direct impact. Of course, it’s always important that your eyes are healthy and that your line of vision is clear.
Which do you see? Why? 
Can you tell which center circle is larger of the two? The center circles in both graphics are the identical size. The one on the left side looks larger because of the smaller circles around it. 
The triangle is an optical illusion that you see because of the angles of the three dark shapes. 
When you look at this Ferris wheel, does it look like it is moving? And which direction is it going? 
Actually,all of the squares are the exact same size! And the little white dots make the illusion of a ball in the middle - can you see it? 
Does one of these men look taller than the others? It is a trick - they are actually all the exact same size! Our eyes just perceive that one is taller based on where they are standing in relation to each other.Generation Y (those born between 1978 and 1994) are the most diligent about complying with their doctor's contact lens wear care and instructions, according to the American Optometric Association's 2011 American Eye-Q survey. And, the survey also revealed Generation Y held top honors for replacing their contact lens cases every one to three months. Congrats Generation Y!
Answer: Your eyes blink over 10,080 times a day! By the end of the day your eyes are tired and need a break. That's why when someone says "it happened in the blink of an eye," it really means it happened fast!
Also, women----your eyes may be more tired then men since you blink nearly two times more than men.
So, rest your eyes---they deserve it!!!
