Vision Tip While Lying At Home Sick

Avoid reading when you are tired or ill.  If you have to read then you should do so for short periods of time, with lots of rest for your eyes in between.

If you are watching television, do NOT turn off all the other lights, but rather, keep a soft glow of light in the room.  And as always, teach your eyes not to stare, to get fixated on one spot,  but rather start to roam your eyes over the screen. And don’t forget to blink frequently!

While natural vision improvement isn’t nearly as profitable as surgery or corrective lenses, you, the consumer, can save hundreds or perhaps thousands of dollars by safely and naturally rebuilding your vision through the use of proven eye exercises.

Computer vision syndrome (CVS) is a temporary condition resulting from focusing the eyes on a computer display for protracted, uninterrupted periods of time. Some symptoms of CVS include headaches, blurred vision, neck pain, fatigue, eye strain, dry, irritated eyes, and difficulty refocusing the eyes. These symptoms can be further aggravated by improper lighting conditions (ie. bright overhead lighting or glare) or air moving past the eyes (e.g. overhead vents, direct air from a fan). CVS has not been proven to cause any permanent damage to the eye.

CVS is caused by decreased blinking reflex while working long hours focusing on computer screens. The normal blink rate in human eyes is 16-20 per minute.

Blinking

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.
