00:00Human eye can distinguish approximately 10 million different colors and has a resolution of about
00:05576 megapixels. However, the brain only processes a fraction of this information,
00:11resulting in our perception of a lower resolution. On average, a person blinks around 15 to 20 times
00:16per minute. This amounts to approximately 28,800 blinks per day and over 10 million blinks per
00:23year. The average human eyeball is about 24 millimeters in diameter and weighs approximately
00:287.5 grams. Despite their small size, eyes are complex organs consisting of over 2 million
00:34working parts. The retina, located in the back of the eye, contains over 120 million light-sensitive
00:40cells called rods and cones. It is the only place in the body where blood vessels can be observed
00:45directly without the need for surgery. The human eye can adapt to low-light conditions. It takes
00:50around 30 minutes for the eyes to fully adjust to darkness, during which the pupils dilate,
00:56and the retina becomes more sensitive to light. The eye is the fastest muscle in the human body,
01:01capable of rapid movements. It can rotate at speeds of up to 500 degrees per second. Tears are not only
01:07shed in response to emotions, but also serve as a protective mechanism for the eyes. They help to
01:12keep the eyes lubricated, remove debris, and contain enzymes that fight bacteria.
