The eyes are one of the most dynamic organs of the body and play a large role in how our bodies respond to what is going on around us. Nearly everything we know about our environment comes from what we see. This makes taking care of the eyes that much more important. Dr. Davis helps to keep the eyes of many individuals in the Colleyville area healthy and functioning. Here are some eye-opening facts about the eyes that you may not know.
Almost 80 percent of the information we take in about our environment comes from what we see. This also means that most of our memories are products of the images we see.
The eyes provide critical information about objects around us, such as their shape and color, how far away they are from us and if they are moving toward or away from us.
The average eye is about an inch in diameter and contains 12 million light-sensitive cells called photoreceptors. The eye also contains six muscles that allow it to move to track objects.
The eye’s main components, the iris and the pupil, help the organ adjust to bright or dark environments.
The pupil also adjusts its size to emotions such as fear and anxiety.
The cornea does not have blood vessels, making healing from injuries a lengthy process.
Images received by the eye are actually taken in upside-down and flipped to right side up in the brain.
The average human eye is capable of detecting 10 million color hues.
Humans cannot see infrared or ultraviolet light, but insects can.
Most people blink at least once or twice every 10 seconds, with the average blink lasting just .3 seconds.
Brown is the most common eye color and is found in 55 percent of the world. Only 8 percent of the world’s population has blue eyes.
Eating carrots to benefit eye health is not an old wives’ tale carrots are high in vitamin A, which is necessary for healthy eyes and good vision. Carrots aren’t the only food high in vitamin A; milk, eggs and cheese are also rich in this important nutrient.
