Today the use of digital devices is on the rise and is higher than they have ever been before. Since these devices have become a larger part of our daily lives, many people suffer from digital eye strain, which has always been thought to be caused by the artificial blue light that emits out of our smartphones, tablets, televisions, and computers. Looking at your devices for extended periods of time could play a major role in how tired your eyes are at the end of the day.
Reading Glasses With Blue Light Protection
Blue light is a part of the visible light spectrum. The visible light itself is a lot more complicated than you think, without getting into the details, all the colors of the visible light spectrum combined to create the white light that you see on a daily basis.
Therefore, blue light is technically everywhere. Our sun is the main source of blue light, and being outdoors during the day is where most of us get exposure to it. However, with the boom in technology, there are many artificial sources of blue light ranging from indoor sources such as fluorescent and LED lighting.
The worse culprits of them all are smartphones, flat-screen televisions, computers, and tablets. The amount of blue light coming off of these devices is very small compared to the sun. However, what concerns healthcare professionals is the amount of time people spend using these devices, as well as the proximity of the screens to the user’s face. Experts are barely scratching the surface on the possible long-term effects of blue light on not only your eye health but your overall health as well.
Check out this video brought to you by VSP Vision Care, talking about the potential effects of blue light on your eyes.
How to Reduce Your Blue Light Exposure
If you are constantly using your smartphone, tablet, or computer a pair of blue light blocking reading glasses could be helpful to reduce your blue light exposure from these devices. Many manufacturers make blue light blocking glasses that you can get without a prescription, or you can even get them with slight magnification to be optimized for the distance that you look at your devices.
If you wear prescription glasses, many manufacturers have created a special anti-reflective coating that also blocks blue light from natural sunlight as well as your digital devices. Another thing that you may consider if you are wearing prescription glasses is photochromic lenses, which provides you with protection from UV as well as blue light both outdoors and in. Photochromic lenses automatically darken when there is UV rays outdoors, which also provides an increased level of comfort, and glare reduction.
Do The Glasses Even Work?
Although there has not been a study that shows how effective all the different glasses, coatings, and filters are at filtering out blue light or helping with digital eye strain. In my experience, my eyes feel more rested at the end of a long day whenever I use my prescription glasses that have the blue light blocking coating.
Before the study from the University of Toledo came out there was little known about what the blue light was actually doing to your eyes. Now that we know the blue light is turning cells in your eyes toxic, it might be a good idea to use some sort of blue light blocking filter, whether it be a filter for your device’s screen, or a pair of blue light blocking glasses.
It is important to remember that these filters and glasses only block a certain percentage of blue light not all, therefore you should definitely make an effort to reduce screen time whenever possible.

The Bottom Line
Although there are many options out there to help protect your eyes against blue light. You still should be more proactive about protecting your eyes from blue light by reducing screen time whenever possible. Also, it is not recommended to look at your devices for prolonged periods of time in the dark. When it is dark, your pupils are dilated, which means more blue light will be entering your eye, putting you at a higher risk of damage.
The research group over at The University of Toledo will be continuing their study to try and figure out what kind of intensity levels of blue light is causing these cells to turn toxic and kill photoreceptor cells.
Until we know more about the long-term damage of blue light, we should all protect our eyes whenever we can, as well as be more proactive about putting our devices down more often, especially at night.
