There Is Much Value In A Blinking Eye

A slow blinking eye

Quote “There can be as much value in the blink of an eye as in months of rational analysis”

Blinking is the rapid closing and opening of the eyelid. It is an essential function of the eye that helps spread tears across and remove irritants from the surface of the cornea and conjunctiva. On average, a blink takes approximately 300 to 400 milliseconds. Blink speed can be affected by elements such as fatigue, eye injury, medication, and disease.

A person approximately blinks once every two to ten seconds. The blinking rate is determined by the “blinking center”, but it can also be affected by external stimulus. When an animal (usually human) chooses to blink only one eye as a signal to another in a social setting (a form of body language), it is known as winking. However, some animals (for example, tortoises and hamsters) blink their eyes independently of each other.

Children

Infants do not blink at the same rate of adults; in fact infants only blink at an average rate of one or two times in a minute. The reason for this difference is unknown, but it is suggested that babies do not require the same amount of eye lubrication that adults do because their eyelid opening is smaller in relation to adults. Additionally, infants do not produce tears during their first month of life. Babies also get a significant amount more sleep than adults do, and, as discussed earlier, fatigued eyes blink more. However, throughout childhood the blink rate increases, and by adolescence, it is usually equivalent to adults.

Adults

Women and men do not differ in their rates of spontaneous blinking, averaging around 10 blinks per minute in a laboratory setting. However, when the eyes are focused on object for an extended period of time, such as when reading, the rate of blinking decreases to about 3-4 times per minute. This is the major reason that eyes dry out and become fatigued when reading.

Eye blinking can be a criterion for diagnosing medical conditions. For example, excessive blinking may help to indicate the onset of Tourette syndrome, strokes or disorders of the nervous system. A reduced rate of blinking is associated with Parkinson’s disease. Parkinson’s patients have a distinct, serpentine stare that is very recognisable.

VisionTip of the Month: Night Blindness Tips

1. If you are at the stage of the Rebuild Your Vision Program where you are still wearing your glasses, choose glasses with an anti-reflective coating to reduce glare.
2. Keep glasses-including sunglasses-clean. Having dirt on the inside or outside of your
   lenses can disturb the filtering of light and scatter it, making it more difficult to see and increasing an already existing vision problem.
3. Keep your car windshield and car windows clean-inside and out. Having dirt and debris on your windshield makes it harder to see, especially at night.
4. While driving at night, avoid looking at oncoming car lights head-on; instead, try to
   look to the side of the lights in order to minimize glare. If your night vision is really poor, you may want to avoid driving at night altogether

Do You Need To Improve Your Night Vision?

I know this one for sure because I did the program and my night vision has improved tremendously

Feature: Why Does My Vision Get Worse at Night?

If you need a nightlight to find your way to the kitchen for a midnight snack, or have difficulty seeing while driving in the evening, you may be suffering from a condition known as night blindness.

People with night blindness see poorly in darkness or dim light but normally when adequate amounts of light are present. The condition is not the nighttime equivalent of true blindness-nonetheless, those who have it know how limiting its effects can be.

Seeing in the dark

It is estimated that most individuals take about 20 minutes to see adequately in the dark. This time allows your eyes to adjust from the brightness of daylight or indoor lights. As the light dims, your pupils dilate (grow larger) to take in more light.

Vision – Colors Explained – The Science Of Color

OK, For Those Who Are Interested In The Science Of Color!

Simultaneous Contrast

Equinox, Hans Hofmann, 1958. Note how the contrasting colors create energetic forms, which Hofmann famously termed “push and pull.”

Two colors, side by side, interact with one another and change our perception accordingly. The effect of this interaction is called simultaneous contrast. Since we rarely see colors in isolation, simultaneous contrast affects our sense of the color that we see. For example, red and blue flowerbeds in a garden are modified where they border each other: the blue appears green and the red, orange. The real colors are not altered; only our perception of them changes. This effect has a simple scientific explanation that we will uncover.

Simultaneous contrast is most intense when the two colors are complementary colors.

Complementary colors are pairs of colors, diametrically opposite on a color circle: as seen in Newton’s color circle, red and green, and blue and yellow. Yellow complements blue; mixed yellow and blue lights generate white light.

Impressionist interest in color and light is influenced in part by the research of scientists like Michel Chevreul. Specifically, the idea that an object of any given color will cast a shadow tinged with that of its complementary color and tinting neighboring colors in the same manner influences Impressionists. This theory was already known to earlier painters, such as Eugène Delacroix.

A primary color such as red has green (the combination of the other two primaries) as its complementary. Similarly, blue has orange and yellow has purple as a complementary color.
Artists have always explored the effects of juxtaposing complementary colors, even without understanding it in neurophysiological terms. Few artists have dramatically used complementary colors as has Vincent van Gogh (1853-1890). Both works were painted in Arles in 1888.

Red and green accentuate each other in van Gogh’s Night Café in Arles, which was painted the same month as the café at left.
