Screen Effect On Eyes

 

Eye experts says that long exposure to the screen on one’s computer or laptop and mobile phones could affect one’s eyes health. It can cause eye strain, headaches, dry eyes, blurred vision, and myopia the experts say.

“Just two consecutive hours staring at a screen puts you more at risk for eye strain, dry eyes, headaches, and blurred vision, according to the American Optometric Association. Most of these problems are temporary, though, says William Reynolds, O.D., president of the American Optometric Association and CEO of Eye Care Center Optometrists PSC in Richmond, KY. “If you get away from the computer and relieve that strain, usually, the problems go away,” he explains……… The closer you are to digital devices, the harder your eyes have to work — and prolonging that position can cause myopia, a condition in which the eye becomes elongated, making close objects appear clear but objects further away seem blurry, explains Reynolds. High amounts of myopia can significantly increase the risk of major eye issues like retinal tearing, glaucoma, or cataracts, according to research published in the journal Progress in Retinal and Eye Research.”(Elemental)

 

Blinking often is essential and necessary the eye experts says but exposure to gadget screen like computer or mobile phone according to the expert reduces the blinking number of our eyes.

“Research shows that a healthy, normal blink rate is between 12 and 15 times per minute; while staring at your computer, tablet, or smartphone, that rate can drop as low as six times per minute. Blinking is essential, because it spreads a film of liquid from your tear ducts over the ocular surface. “Think of your eye like an ice skating rink that’s being skated on. Those blinks kind of act like a Zamboni,” Davidson explains. “We need them to lubricate and resurface the cornea.””(Elemental)

 

Another issue according to experts to digital device in pertaining to eye health is the light the screen emitted which is they called “blue light”. According to the experts, blue light could no able you to sleep and thus making eyes not able to replenish and lubricate which necessary for our eyes.

Exposure to “blue light” according to experts says can lead you to macular degeneration and to blindness.

“There’s also the issue of blue light, a type of short-wavelength light commonly emitted by digital devices. Studies have shown that exposure to this kind of light can disrupt sleep (denying our eyes yet another opportunity to lubricate and replenish), and some research has identified it as a risk factor for macular degeneration, which can lead to blindness. “Blue light exposure may increase the risk of macular degeneration and does contribute to eye strain,” says Davidson. The macula is an oval-shaped, pigmented area near the center of the retina; it provides the central vision we need for seeing detail. “We know that blue light can affect the pigmentation of the macula, which is concerning,” adds Reynolds. “Anything that affects the function of the macula would decrease our central vision.””(Elemental)

 

The main point: Long exposure to the screens of digital devices like smartphone, tablet, and computer or laptop according to eye expert cause a major eye health problem for example myopia and macular degeneration.
