How to Prevent Eye Damages from Computers, Cell Phones and More
Vision is the sense most heavily
relied on by modern, technological society. Hearing may come in as a close
second, but even without a sense of hearing, we could still navigate most
electronics. Without our eyes, that becomes a laborious task. But what,
exactly, are the screens we look at so much, doing to our eyes?
Blue Light Damages the Retina
Those glowing flat panes, held mere
inches from our face, emit a powerful light that can, opticians say, lead to
permanent eye damage. Much of the light that comes out of a screen is
blue-violet. Studies show that, over time, too much exposure to blue-violet
light can injure the retina. Retina damage can lead to macular degeneration,
the most common cause of geriatric blindness.
Microwaves
Another source of eye injury is the
microwave radiation emitted by cell phones. In an Israeli study, the lenses of
calves (which strongly resemble humans) were exposed to the heat and the
microwave level emitted by a cell phone. After two weeks, the cells showed
signs of damage that limited their ability to focus light. Some had also
irreversibly bubbled, a precursor to developing cataracts.
Eye Movement Saccades
A related problem is that when we
focus on our screen tiny eye movements called saccades are disrupted.
Saccades deliver refreshed visual information to the brain and blinking
momentarily disrupts the saccade. So, when we need to focus our vision,
gazing at our tablet, the blink rate slows so that we can continue the saccades
without interruption. And in turn, when blink rate slows, the protective
tear film covering the surface of the eye begins to deteriorate. The tear film
not only keeps our eyes moist, but brings nourishment and removes waste.
The end result is dry eye syndrome and red, irritated, tired eyes.
Blink Rate
Not only that, but our blink rate is
reduced significantly further contributing to dryness. Normally we blink
about 18 times a minute, but on electronic devices, we blink only about 6 to 9
times a minute or less.
Heavy Usage
The average adult spends seven hours
a day in front of a screen, and twenty-somethings check their cell phones about
32 times a day. The technology is too new to know how all that time will add up
in later life, when our senses deteriorate anyway. Further research is needed
to clarify potential risks.
In the meantime, to be on the safe
side, opticians recommend turning down screen brightness and decreasing screen
time when possible. Heavy users can also purchase a screen cover to decrease
exposure. Avoid staring at a bright screen in dark lighting conditions, such as
checking messages on your cell phone in a dark bedroom. Taking breaks,
remembering to blink and attention to exercise, diet and proper supplementation
can also help to prevent eye damage from screens. Check out our tips for
avoiding eyestrain from computers. These points are also
important for all users of mobile devices.
TheraLife Eye is effective in reducing inflammation and stimulates tear flow for chronic dry eye relief. Often people with chronic dry eyes also have Blepharitis. Treating chronic dry eyes reduces the inflammation, and also helps to reduce the recurrence of blepharitis. It is highly recommended that those who have Blepharitis stay on TheraLife Eye long term to increase the rate of success.
