Should You Be Concerned About Blue Light Exposure? (Infographic)

By on

By the time the average American child reaches age 17, their eyes will have spent the equivalent of nearly six years looking at digital devices according to findings from a new survey by VSP. With so much screen time in today’s world, our eyes are being exposed to an unprecedented amount of high-energy blue light which is emitted from devices like smartphones, tablets, TVs, and even CFL and LED lights. Blue light has caused a huge increase in digital eye strain not only in adults, but also children. The blue light coming off our favorite screens is extremely difficult for the human eye to focus, which causes our eyes to work overtime to try and process it which can lead to headaches, tired eyes, and blurry vision.

From the classroom, to the office, and nearly everywhere in between, digital devices are becoming more and more prevalent in our lives. Yet, survey results show that parents are largely unaware of blue light and its impact on vision. So what can you do to reduce exposure to blue light? Explore the infographic below to learn more.


TechShield Blue is a next-generation anti-reflective coating that absorbs and reflects the specific blue light wavelengths associated with digital eye strain. This near-clear coating is a great choice if you spend two or more hours a day in front of a screen or under an LED. Talk to your VSP eye doctor today about reducing your blue light exposure.

  • Do the blue light filter apps that are now available really help at all?

    • Eric Anderson says:

      Yes, but only a little. It will change all color of “white” light and “blue” to reduce the amount of blue lighting. – That’s at least what my eye doctor told me.

  • Robert Chappell says:

    Is there a coating for lenses that blocks the blue light ? Are there clip-on lenses that block the blue light ?

    • Angelina F. says:

      Hi Robert – Your VSP eye doctor can recommend the right product to reduce blue light exposure. One option could be Sharper Image TechShield, which is a coating that is applied to the lens which absorbs and deflects blue light. You can learn more about it here:

  • Dave says:

    Try the program f.lux which will change the color temperature of computer display, reducing it according to the position of the sun. This reduces the blue light in the early morning and evening.

  • Holly Jay says:

    I would like to know the research behind this information. Please send me a full copy of the scientific study.

    I got the coating on my last pair of glasses and what a difference! My eyes don’t feel as gritty/tired and it seems my headaches are reduced. I definitely notice less eye strain. Only thing is the coating reflects blue so I get a lot of comments on my blue lenses

  • Elizabeth Vollstadt says:

    Is there a tint on glasses that would help?

      Hi Elizabeth – Talk to your VSP eye doctor about your lifestyle (i.e. how much time you spend in front of a digital device/computer/etc.). They will be able to recommend the right product for you. One option could be Sharper Image TechShield, which is a coating that is applied to the lens which absorbs and deflects blue light.

        I have the techshield blue coating on my new lenses and I do not like the blue glare in them. Can the coating be removed?

  • Rae Zimmerman says:

    Thank you for the 5 tips. We will incorporate them into family routine. Our teens are already limited to 1 hour of electronics, except tv, per say out of school and nothing after 8 pm!

  • Mike Kestie says:

    I have started wearing some blue-tech glasses and have noticed a difference on how my eyes feel at the end of the day. They have helped me and reduced the number of headaches. I work on a computer throughout most of the day.

  • Sandra G Pressley says:

    This was very informative I had no idea. I am 71 and have essential tremors so I use a kindle fire for reading my Bible, sometimes for hours at a time and I do have a problem with blurred eyes. I have been to have my eyes checked and I have had dry eye problem long before I had my kindle. It is being treated though and I do read a lot some days because I am home alone. Thank You , Sandra Pressley

    Love this article! We are moving to an online school with my daughter in the fall and her eye doc prescribed blue blocking lenses. After 9 months in Vision Therapy – we didn’t want to risk any regression and anything we can do to protect our most precious tools – we are willing to pay for! This is a great article! So many parents are so misinformed about vision. Thank you!

  • RNO says:

    I had no idea regarding the existence of a coating to reduce bluelight exposure. After being on the laptop, tablet, and phone, my eyes are blurry on the way home from work. I will be sure to talk to my doctor about this. Thanks for the info!

  • Chelsea says:

    It’s actually a great and helpful piece of info. I am satisfied that you just shared this useful info

    Hi friends, good post and nice urging commented here, I am actually enjoying by these.

  • Ping says:

    Do they have blue light clip-ons available? I do computer and non-computer work so I want to be able to remove them if no computer work is being done.

  • Rita says:

    Hello! Interesting article. Does the coating on the lens that helps limit the blue light exposure affect your driving vision in any way? Are street signs/lights more dim compared to normal?

    • Patrick I. says:

      Hello! Thanks for your question. TechShield Blue reduces blue light exposure from LED’s that we perceive visually as glare; these LED’s are used primarily in device screens, however if the streetlights or other light sources you encounter when driving are LED’s, then TechShield Blue will also reduce glare from these sources. This won’t make the lights seem dimmer, but it will reduce glare. Remember that TechShield Blue is designed primarily to improve visual comfort when interacting with device screens, and if you spend time in a variety of different lighting settings you may want to consider a blue light reducing light reactive lens from our SunSync product line – these lenses offer blue light reduction indoors and UV protection and blue light reduction outdoors.

      Hope this helps! -Patrick I, VSP

  • Brian says:

    Useless article: Title contains a question mark – hint that the following info is probably meaningless conjecture.
    Article has useless statistics: 50% parents say kids are addicted to digital devices. So what – prove it’s bad and report something conclusive. A survey of feelings is useless. Eyestrain increase? How about actual testing compared with similar time reading a book. Strain is normal when you use any muscle – so what next – “don’t exercise it may cause strain”. Solution to strain is obvious – cut back if you’re bothered. Don’t spread non-scientific fear causing articles.

    I pay a quick visit everyday some web pages and information sites to read articles, however this website presents quality based writing.
