Eye Facts

Eyes are amazing little things that give us the ability to see and observe our environment, so we at StaxonDigital made a little list for “Eye Facts” that we think you might think like and also learn new things that you didn’t know about the eyes. Eyes may be the windows to the soul, but how much do you really know about them?

1. If the human eye was a digital camera it would have 576 megapixels.

The eye is not a single frame snapshot camera. It is more like a video stream. The eye moves rapidly in small angular amounts and continually updates the image in one’s brain to “paint” the detail. We also have two eyes, and our brains combine the signals to increase the resolution further. We also typically move our eyes around the scene to gather more information. Because of these factors, the eye plus brain assembles a higher resolution image than possible with the number of photoreceptors in the retina. So the megapixel equivalent numbers below refer to the spatial detail in an image that would be required to show what the human eye could see when you view a scene.

2. We spend about 10% of our waking hours with our eyes closed, blinking.

Eye Facts: We all blink. A lot. The average person blinks some 15-20 times per minute—so frequently that our eyes are closed for roughly 10% of our waking hours overall.

3. Researchers have successfully used the game TETRIS to treat “lazy eye” in adults.

TORONTO — Patching has long been used to treat a lazy eye in children, although the therapy has limited success and doesn’t work at all in adults with the condition formally known as amblyopia.

Now researchers at McGill University in Montreal are testing an innovative means of improving visual function in adults with lazy eye — a puzzle video game that forces both eyes to work together to overcome the common condition.

4. Albert Einstein’s eyes remain in a safe box in NYC.

He removed Einstein’s eyeballs and gave them to Einstein’s eye doctor, Henry Adams. To this day, they remain in a safe deposit box in New York City. As Brian Burrell wrote in his book, “Postcards from the Brain Museum,” “Why [Harvey] kept it will never be known for certain, but it can be inferred from comments made to various reporters that Harvey was inspired by Oskar Vogt’s study of Lenin’s brain, and he had the vague idea that cytoarchitectonics might shed some light on Einstein’s case [looking for physical proof for why Einstein was so smart]. A simpler and more appealing explanation is that [Harvey] got caught up in the moment and was transfixed in the presence of greatness. What he quickly discovered was that he had bitten off more than he could chew.”

5. Your eyes can get sunburned.

That’s why it’s so important to wear sunglasses that protect against UVA and UVB rays. Sunburn to the eye isn’t the same as sunburn to the skin, where the effects are relatively immediate with pain, redness and peeling. When sunburn occurs to the eye, it’s over a long, gradual period of time; the prolonged sun exposure will eventually lead to thickened tissue within the eye, which might necessitate eye surgery.

6. Bees have five eyes.

On its head, a bee has two sensory antennae. It also has five eyes — three simple eyes, or ocelli, and two compound eyes. The compound eyes are made of lots of small, repeating eye parts called ommatidia. In each compound eye, about 150 ommatidia specialize in seeing patterns. This allows bees to detect polarized light — something human beings cannot do.

7. It is impossible to sneeze with the eyes open.

Nothing much to explain here, try it for yourself, we bet you can’t!

8. Why are night vision goggles green?

Night vision goggles are green because the human eye can differentiate more shades of green than any other color.

These were all the facts that we compiled for you today, if you enjoyed “Eye Facts” please make sure to read our other articles we cover a variety of subject and we post every day!
