From the moment you wake up in the morning to the time you go to sleep at night, your eyes are acting like a video camera. Everything you look at is then sent to your brain for processing and storage much like a video cassette.
How Your Eyes Work? Take a moment to locate an object around you. Do you know how you are able to see it? Would you believe that what you are actually seeing are beams of light bouncing off the object and into your eyes? It is hard to believe, but it is true. The light rays enter the eye through the cornea, which is a thick, transparent protective layer on the surface of your eye. Then the light rays pass through the pupil (the dark circle in the center of your eye) and into the lens.
Color Perception: Light as we see it runs from Ultra Violet (where it leaves our perception) through Violet, purple, blue, green, yellow, orange, red, and ultimately to infrared, whence we again cannot see it. You can 'loop' this spectrum by letting the red go further from orange into violet mode. It is more like a color wheel continually flowing than individual colors. All colors can be darkened with black or lightened with white. But are black and white colors? Yes -- ALL colors mixed together make black, and, if done with light, all colors together make white light.
Overall, the only perfect color is white -- and all the other colors are breakdowns thereof, in some combination. How many distinctions in color can a human eye see, varies greatly from individual to individual. Some person may be able to perceive 128 shades between red and orange. Someone else may only be able to see red, red-orange, and orange. Some people may see the color brown in burgundy, others only dark red/purple. Some of us are better able to filter colored light out of solid color and see color more distinctly. Other things, like fog and moonlight, tend to filter all color out, while still keeping things very beautiful. The only whole color, however, is white. Everything else is a breakdown of white. Mix all the colors up and you get black.
Our eyes are wonderful blessings from God. See how complex it works and how it gives wonder to our life – from taking photographs to seeing our loved ones, to the colors of the rainbows, the green fields, the wonderful colors of sunset, and to everything around us.
Here’s my “take five” - the best things to look at
1. The faces of my loved ones
2. The sunrise
3. The eyes of an innocent child
4. Anything green (excluding my gray matter)
5. My own face – no matter how “whatever” my look is... i still love to look at my own face because it reflects to the biggest and unconditional Love of GOD.
With all these wonderful things, it is our obligation to take care of our eyes. My lil' advise - Don’t spend too much time at your computer, if it indispensable, take a few minutes to rest your eyes from time to time, at least every two hours and do some eye exercise after wards. Like moving your eyes up and down for several times, then left and right, then clockwise and followed by counter clockwise. This will help you to reduce some eyestrain and stress too.
