Mobile Phones and your eyes
Can mobile phones really damage your eyes?
Nowadays, everyone spends a good portion of their waking hours staring at their mobile phones or computers. But in the grand scheme of human history, this is a very recent phenomenon: only since our generation do people stare at screens this much. Therefore, our eyes have not (yet) evolved to withstand such overuse.
And yet new studies have shown that the LED screens of our mobile phones emit High-Energy Visible light (HEV), also known as "Blue light". These highly active light rays pose a problem to our retinas. Our retinas have about 126 million tiny photoreceptor cells which absorb light rays and convert them to visual signals to the brains. Just above these photoreceptor cells is a thin layer called the Retinal Pigmented Epithelium (RPE) which consists of many hexagonal shaped cells which not only absorb light but also keep our photoreceptors healthy by removing waste and preventing oxidative damage.
The problem is, this intense blue light is causing immense amounts of stress on the RPE layer, preventing it from functioning optimally. The result? Cells get damaged, waste product accumulates and oxidative stress is elevated. This prolonged assault could eventually cause age-related macular degeneration.
So how do we prevent such damage?
With most of us being socially hyper-active online, it is becoming increasingly difficult to keep our phones away from our eyes. One way to reduce the intensity of Blue light transmission is to simply reduce the brightness of your screen.
But the best option available is to adorn a pair of optical lenses equipped with a filter which will prevent the harmful blue light from reaching your retina.
If you already wear glasses, you can get a blue light filter as an option when ordering new prescription lenses.
If you don't wear glasses, you can buy a pair of non-prescription screen glasses, like the SeeConcept Screen Glasses which will block blue light and make you look smart around the office. They even come in kids sizes!
Keep in mind that both of these options will block a good portion but not all blue light. Which is a good thing: some wavelengths of blue light have an effect on your circadian rhythm, which helps you sleep. As with many health issues, this is a matter of balance.
In a nutshell: please control the amount of time you and your child stare at your screens, or wear appropriate glasses!
Stay Healthy & Stay Happy!
