Everyone has a different blinking rate. An area of the brain called chordate nucleus controls blinking, it sends impulses down the nervous system and into the muscles of the eyelid. Most people blink once in 2 - 10 seconds. Blinking can also be triggered by anything trying to get in contact with the eyes like dust and pollen.

The eye is a very sensitive part of the body. It can be more vulnerable than the other senses and would need to be taken care of more. It is common that people will sometimes get soap, shampoo, and other chemicals in their eyes.

If in case this occurs, they need to flush out the chemicals with water. If the irritation persists, seeing a doctor is necessary. There are still other causes of eye injury though such as getting your eye scratched by your own nails or another object.

Even rubbing your own eyes can cause corneal abrasion so you should avoid doing this. Eye swelling is also another possible cause of eye injury. Getting hit by a hard object in the eye such as a fist or other hard objects can definitely cause eye injury.

Cataracts are these days easily treated.

The operation is apparently painless and excellent results are typically reported. Another common eye disease is conjunctivitis where viral or bacterial infection has caused swelling of the thin transparent layer of tissue that lines the inner surface of the eyelid and covers the white part of the eye.

When you yawn you may screw up your eyes and prevent the normal diagonal flow of fluid across the eye so that it seeps out of the corners. Your facial muscles around your eyes pull tight, putting pressure on your lacrimal glands. These glands produce the watery component to natural tears. Your lacrimal glands are sited deep beneath our upper eyelids.

They produce the watery part of the eyes’ natural tears. Their function is to produce and release tears slowly throughout the day so the surface of our eyes is coated at all times. When you yawn, pull your eyes tight, and put pressure on these glands, the water is pressed out. You may notice a difference if you yawn keeping your eyes open. Try it.

Brown eyes occur less often than blue, but it is due to the amount of melanin, just as it is with skin colour. All babies, even in people with the blackest skin, are born with blue eyes, though these may be dark blue, like a navy. But within 12 to 18 months, more melanin can accumulate in the iris.

Then eye color changes from blue to green, hazel or brown. Brown eyes are said to be dominant hereditarily, but a brown eyed parent may still produce a blue eyed child if their partner is blue-eyed.

Each person has their own sensitive body part, but some body parts overall are more sensitive than others. Eyes are not the most sensitive. It is hard to believe that the fingertips are the most sensitive. If you imagine, you get debris in your eyes. It may be uncomfortable, but it doesn’t make you wince in pain. Squeezing your fingers or pinching them may make you wince.

There are also other body parts that are close to the sensitivity like the fingertips. These do include the eyes, tongue and lips. Whenever you injure those parts, you will take notice compared to other parts of the body that aren’t affected as much. There are also parts of the body that have protection like the eyes; they have eyelids for protection.
