How to Limit the Impact of LED Lighting in the Age of Technology

For thousands of years in human development prior to the ascent of our technological age, individuals likely had the following night time routine.



They would likely spend a few hours cleaning animal waste, mopping the floors, or whispering bedtime tales to their children. As the home got dark, they would pull out wax candles, or read a book by a rickety fireplace. As your eyes sauntered off and your body waned from the work of the day, you likely tucked under your bed and blew out your candles.

A routine like this likely proceeded for millions of members of in our species for most of our evolutionary history. Today, however, LED blue light has altered these conditions—and at a far higher rate than our eyes have been able to adapt.

Recently, an authority in French Health released a report which catalogues this trend in modern life, and he was conclusive. LED lighting and its increased use in our homes—be it phone screens, computers, or television—is disrupting the retinal health and sleep routines of millions.

Referred to as “photo-toxic,” blue light sends powerful rays which inflict damage on your macula, the vision center at the center of your retina responsible for the center of your vision.[1] These powerful amounts of damage to your retina will not only impact your ability to sleep well at night, it can even take away sharp vision altogether. 

The leading cause of blindness for Americans over the age of 50 is Advanced Macular Degeneration, or AMD. The likelihood that you can develop this eye related disease only increases with age and with excess exposure of blue lights to your macula.

And blue light is not likely going away. As the United States Department of Energy makes clear, Blue lights will constitute 48% of total luminous energy sales by 2020, and close to 84% the following decade.[2]

Since cellular devices and phones are such an essential component to both how you manage your life and how most make their living, it is silly to expect that anyone would react to this problem by closing down their devices completely.

This does not mean, however, that there are strategies you can implement to limit the damage of LED lighting in your own life and restore a level of eye health more common to the good-ol’- days. 

  1. Wear Protective Blue Light Glasses

A market of blue light protective lens has arisen to address and lessen the effects of LED lighting on your eye health. Blue lens glasses serve as a filter when you are working on your computer throughout the day, or even staring at your iPhone when waiting in line at the store.

Most protective lens come with an LED light testing feature with a small LED flashlight Be sure to get one that will test the lens before you wear them in your day to day activities. You want to ensure that the work you are doing to prevent blue light is coming to fruition. 

  1. Readjust Your Computer Screen

If you must spend hours a day at a computer (like so many Americans do), there is a way to mitigate how much blue light makes it to your eyes. In addition to wearing a blue lens, look down when you are working at your computer.

Staring up at a screen or a phone puts direct focus of the blue light on your eyes, whereas looking down at the screen at a distance of 10 inches or more mitigates blue light impact. 

  1. Do Not Look at a Screen 1 Hour Before You Go to Sleep

Sleep is promoted by a hormone that is native to your body—melatonin. When you stare at a blue light screen, your eyes stay open far longer and you blink much less. This interrupts the process in your brain to produce melatonin and promote proper sleep rhythms.

Often times, those who stare at a screen before bed will keep their brains on and disrupt the 8-hour window needed for healthy brain and body function the next day. This is why many doctors recommend turning off all electronic devices at least 1 hour before you know you are going to bed. 

  1. Nourish Your Eyes with Lutein Through anEye Health Vitamin

While there are many environmental strategies you can implement on behalf of your eyes and your macula, there are many eye health vitamins which are essential to replenishing your eyes that our bodies cannot fully produce naturally. Think about Lutein, the only Carotenoid pigment in nature out of 600 others, that is native to your eyes.

Your body does not provide sufficient levels of Lutein, which is a Carotenoid that is essential to sustaining your retina. And while you can work to provide your eyes with enough Lutein by eating enough leafy green vegetables, this is not always a reliable scheme. You may be in a rush, or perhaps leafy greens are not available to you everywhere you go.

This is why many doctors recommend patients turn to an eye health supplement which contains necessary nutrients like Lutein to replenish their eyes as part of their daily regimen.

The growing prevalence of blue light in your life means that, now more than ever, your eye health is essential to preserve and protect.
