Depth perception is the visual ability to see the world in three dimensions. Some, but not all animals also have this ability. Depth perception lets the "seer" to accurately measure the distance to an entity.
You Have Two Eyes - that means - two different views! (Close one eye & Look out the other - you will see different in each eye) We all (generally) have two eyes and one brain that processes what we see. The difference in our visual perception out of each eye gives us the 3D effect. (This is a simple explanation.
Here are some activities that require 3D Vision - parking your car - playing ball - constructing 3D objects - seeing things that go up and down (like steps and curbs).
These are just a few of the daily uses of our 3D vision! There are many different reasons why you may NOT have 3D vision. Always see your doctor. And, always take a pro-active role in your eye care.
Do you have 3D vision? One simple test (not for diagnosis or treatment - just for entertainment)
1) Look at a 2-3 inch square picture on your computer. 2) Now, put your thumb about 1 foot right in front of your nose between your two eyes.
-- focus on the picture, you should see two thumbs -- focus on the thumb and you should see two pictures.
You can take an active role in your eye care. One way is to actually exercise your eyes. Become aware of your visual being. When you wake up this morning and go through your normal day, try something new! Take a look around you. Make use of your peripheral vision.
Have you ever driven down a street in your neighborhood, let's say on a beautiful summer day, and just really looked around? And thought, wow, this doesn't even look like my street!
Well many of us go through our days as if we had blinders on. Try something new. Look around. Look up, and down, and left and right. Don't just see what's there, really look at what's there! You will be surprised what you may find. And, your eyes will be healthier. The more you use your eyes, the better they get.
The more you "daydream-fixate" the more they "stagnate" so to speak. So, become mentally alert, and exercise your eyes at the same time. One extra bonus is: Your life may get less boring and routine when you do that.
