Eye coordination of both eyes is the ability of the left and the right eye to work together like a team. It is actually the functionality of your brain that blends the images captured by each of your eye and creates a single three-dimensional image. The picture seen by each of your eye is different from each other and will only be noticed if you view the same image with one eye closed each time. The coordination of eyes is a skill that should be developed. Improper eye muscle control and inadequate vision development also results in poor eye coordination. Sometimes, a disease or an injury may also cause an individual to develop poor eye coordination.
Signs of Poor Eye Coordination
Some symptoms and signs that indicate poor eye coordination include headaches, double vision, body and eye fatigue, dizziness, irritability and difficulty in concentrating and reading. Certain symptoms and signs are also common in children indicating poor eye coordination. These include covering one eye, poor sports performance, losing lines or place during reading, being unable to perform tasks that require focus and concentration.
Since it is not easy to detect poor eye coordination, it is recommended to conduct periodic optometric examination. This is a comprehensive examination conducted by a doctor to determine the extent of poor eye coordination. Poor eye coordination can be treated with vision therapy and/or eyeglasses or lenses.
Why two coordinated eyes are better than one?
Having two eyes is indeed better than a single eye because coordination between two eyes provide us with depth perception and stereo vision – these are two things that can never be achieved with one eye. There is a 2.5 inch gap between the two eyes, creating a slightly different angle for the same view. For example, if you raise up a glass and look at it with one eye closed, you will notice that the view of the glass is different when you look at it with just your left eye.
When you look at an object with just your left eye, you will actually see more of the left side of the object. Similarly, when you look at the same object with your right eye, you will be able to see more of the right side of the object. And finally, when you put the two images captured with different eyes on top of one another, you will see that the view will not match and the vision will be out of focus. But our brain is designed to sort out these problems and varying visual views from two eyes together, by combining the images, the brain very successfully recreates the vision picked up by two different eyes to create a single three-dimensional image.
This functionality of the brain is referred to as binocular vision. Just like the two lenses of binoculars, human eyes view the world with two eyes. However, human eyes are placed differently as compared to many animals and birds. Many animals and birds have one eye placed on each side of their head with more gap. This enables them to see a completely different area on the left and right with the left eye and right eye, respectively.
Also, there is a depth perception associated with the view of two eyes. Close one eye to look at an object and you will see how it looks much flatter than it appears in front of two eyes. Moreover, the coordination between two eyes is also very important as mentioned above.
With both eyes well coordinated, a person can experience optic flow in information with a single eye. According to scientists and doctors, people experience difficulties on a daily basis suffering from strabismus (wall-eyes or crossed eyes) and cause poor static depth perception troubling people with threading a needle, driving or parking car. However, poorly coordinated eyes can be treated with vision therapies, medication and even with the proper usage of the right glasses or lenses. Today, people can successfully overcome binocular disorders or effects of strabismus and save their daily life from these hindrances.
