Keeping your eyes healthy while using electronics

Every day my son is on the computer, iPad or his game system. He never gives his eye a rest unless he is sleeping. If we go out, he is watching the Tv in the car, on his iPad or his phone, and sometimes he ends up getting headaches. I tell him it is because he was on his electronics all day and has to give his eyes a rest because looking at a screen for two hours or more can lead to eyestrain. Luckily” I recently found Blueberry Glasses for your eyes. The current digital world is boundless, and we are constantly connected to – smartphones, tablets, computers, television and video games, etc.”

Screens are part of our daily lives, and all these devices emit very strong light waves. Despite ourselves, we are exposed to blue light sources for very long periods which strains our eyes.

I had my son wear these glasses. And he was not too happy,  as it is what Mom was telling him to do. But, he did say his eyes were not as tired as they usually are when he was done playing. I have always wondered if the blue lights from the electronics would affect your eyes and now I have proof that it does

These are some things that can happen.

1. Computer Vision Syndrome

Staring at digital screens (tablet, computer, cellphone, TV, iWatch, Fitbit, car GPS) affects your eyes so seriously that health experts have coined the term, “Computer Vision Syndrome,” or CVS. Though the term was initially used in the context of office employees who spent hours in front of their computers, today the increased symptoms associated with CVS affect millions around the world regardless of age or occupation. Those can include:

  • Eyestrain
  • Headaches
  • Focusing difficulty
  • Itchy, burning, or watery eyes
  • Dry eye
  • Double vision
  • Blurred vision both in distant and nearby objects
  • Sensitivity to Light (also called photophobia)

Any of these can be mild or disabling – and natural when the eyes are working so hard. When you glance at electronic devices, a couple of things occur which increase the likelihood of CVS symptoms.

You Blink Less –The human eye under normal conditions blinks 12-15 times a minute. However, when your brain focuses on a screen, you forget to blink and the count can go down to a mere 7-8 blinks a minute. Every time you blink, you spread a layer of tears over your eyes, so less blinking means your eyes get less lubrication which leads to dry and sore eyes.

You Use Unfavorable Angles – As opposed to reading printed text where you normally look down to read, when starring at a screen the eyes are usually focused straight ahead. When looking down while reading, your eyelid covers more of your eye than when you look straight on. This means looking at a screen angle exposes more of your eye to the air’s drying effects.

This unfavorable lid positioning, together with a reduction in blinking, leaves you with uncomfortably dry eyes and even visual fatigue. Cell phones are changing some of this – but then think of all the careful selfies people take just to get the perfect pic.

You Get Too Close for ComfortYou may have already noticed that when reading on your smartphone, you usually hold it closer to your eyes than you would with traditional printed text. And you are not the only one.

A 2011 study found that nearly all their subjects placed their phones 12.5-14 inches from their eyes to read mobile text while the average distance for printed text is nearly 16 inches. This means that your eyes are forced to work harder to focus at close ranges by having to almost turn cross-eyed, which tires out the eyes.

2. Retina Damage

If you do not carry your phone or laptop with you when you go to bed, you are in the minority. Almost 60% of adult Americans have adopted this habit and replaced their alarm clocks with digital technology. This habit however, can cause significant damage to your eyes.

According to the American Macular Degeneration Foundation, direct exposure to the blue light emitted by LED devices can really damage the retina. The retinal damage that occurs from starring at the blue light – especially at night – can lead to macular degeneration and damage your central vision (the ability to see things right in front of you).

As you age, this becomes even more important, and your retina becomes more sensitive to damage, which can often leave you with additional age-related macular degeneration.

3. Possible Cataracts

Although more research is needed when it comes to the link between cataracts and blue light, doctors are beginning to observe patients in their mid-30s with eyes as cloudy from cataracts as people in their mid-70s. To be clear, this is not definitive proof that exposure to blue light causes cataracts, but there might be a link that deserves further investigation.

4. Eye-related Issues: Headaches

Headaches are the third most common negative effect of your eye’s overexposure to digital devices.

When you stare at a screen for too long, the eye strain that occurs often results in tension headaches. This is because of the darkness of the text, contrasted against the bright screen, makes your eyes work harder to focus and results in muscle spasms at the temples.

Blueberry glasses work to prevent any of these problems from occurring. You can pick different styles, colors, and sizes while protecting your eyes.
