I recently wrote about how the ‘blue light’ from mobile phones, tablets, computers and LED lights are being linked to increasing the incidents to some forms of cancer. That particular wavelength of light has a negative impact on the body’s ability to produce melatonin, which is vital in helping to regulate a person’s internal clock, which in turn disrupts the normal sleeping pattern. When this happens, it interferes with the body’s production of vital hormones which are produced while a person is sleeping. Some studies have found that the decrease in these hormones increases the risk of developing breast cancer and prostate cancer.

A few years ago, there were rumors floating around that holding a cell phone to your ear too long submitted your brain to the electromagnetic waves or frequency waves and these could cause brain cancer or other health issues but those rumors have never been proven, so cell phones are off the hook.

However, there is a new health issue concerning cell phones that some say is reaching epidemic proportions.

As cell phones have become more popular among young people, optometrists and ophthalmologists have seen a huge increase in a vision condition known as myopia, more commonly known as nearsightedness.

As a rule, myopia is defined as when the eye becomes more elongated front to back, causing the center of vision to be in front of the retina in the back of the eye instead of focusing on the retina. This causes people to see better close up (hence the common term nearsightedness) but they have problems focusing on distant objects.

Myopia is treated with corrective lenses or contact lenses that change the focal length of the eye.

So, what do cell phones and computers have to do with more young people becoming nearsighted?

Many of us will remember back when we were young and stood too close the television and our parents would tell us to move back because it would hurt our eyes or cause us to need glasses. There was more truth to what they were saying than we thought.

It all has to do with how much time a person spends looking at their cell phone or computer screen. Watch most young people with their cell phones as they hold it only a foot or so from their face, forcing their eyes to focus on the close screen.

There is a circular muscle on the eye that controls the focus of the eye. When you focus on something up close, the muscle squeezes the eye, making it more elongated. The eyes of younger people are more liable than the eyes of adults and they will elongate easier. The longer the eye is elongated, the more likely the eye will remain elongated which means becoming nearsighted. The same thing happens when you sit in front of a computer screen for long periods of time.

The problem with cell phone use and young people is so prevalent that the American Academy of Ophthalmology has predicted that by the year 2050, close to half of the world’s population will be nearsighted and they believe that the main reason is the habitual use of cell phones and computers.

In a study, they also found that kids who spent more time outdoors were less likely to become nearsighted, which they attribute to the kids focusing on many objects at various distances.

So, what do they recommend to avoid becoming nearsighted? Parents can limit the time their kids spend on their phones but it’s easier to use the 20-20-20 rule. After every 20 minutes with a cell phone or using a computer, take a 20 second break and focus on something at least 20 feet away. I know one expert that uses the 10-20-20 rule in which after every 10 minutes of cell phone or computer to focus on something 20 or more feet away for 20 seconds. Doing this could save your vision or the vision of your child and prevent the need for glasses, contacts or corrective surgery.
