Protect your eyes from harmful blue light

By on

Have you ever heard of blue light? Maybe not, but you’re mostly likely being exposed to it right now by looking at a screen on your computer, tablet or smartphone.

Yes, the digital devices we have become so dependent on may actually be harming our eyes. That’s because the screens on these digital devices, along with fluorescent lights and even the sun, are actually emitting a harmful wavelength of light.

Effects of Blue Light

This so called blue light is harmful because it can penetrate all the way to the back of your eyes, which is unlike most wavelengths of light. That doesn’t mean your eyes only see things in blue, but it does mean that over time you may have a greater risk for eye diseases like macular degeneration. [Read related article on why the sky is blue.]

You may be asking why the worry about blue light now–especially if the sun emits it, too. While that’s true, we used to come inside at night and not be exposed to blue light at night. Now, society has morphed into a 24/7 digital society and our exposure to this harmful light is fairly constant all day every day.

Protecting Your Eyes

You can protect your eyes in a couple ways. The main way is to limit your screen time. If, however, you’re constantly attached to a screen, you should look for a lens solution that filters out the harmful blue light before it reaches your eyes. UNITY lenses are available with BluTech technology to do just that. The good thing is that these lenses don’t distort color and actually relax the eyes. [Learn more about UNITY lenses.]

    • David C. says:

      Hi Bernice, you may also want to try the 20-20-20 rule. That helps keep your eyes fresh throughout a long day of computer use. Every 20 minutes stare at something at least 20 feet away for at least 20 seconds. This engages your distance vision and helps to “reset” your eyes. -David, VSP

    I work at a computer all day long and if I am out of the office then I am using either my laptop or phone to answer emails. Did not know that using these devices could damage my eyes.

  • Lavella Jackson says:

    The field “before today, had you heard of Unity lenses” doesn’t work so I can’t enter the contest.

  • j says:

    Your “required” unity today does not work.

  • Jennifer says:

    It will not allow me to check that I have heard of unity lenses before.

    • David C. says:

      Hi Jennifer, sorry about that. It could be a browser compatibility issue. If you can try another browser that may help. -David, VSP

      • With all of the e-mails concerning this subject, why don’t you just fix the problem on your end? It is possible to employ a fix so that your site is more compatible to multiple browsers.

        • David C. says:

          Hi Salvador, great question. The blog platform is a third party software (Word Press) and is not always compatible with older browsers. This is not something we can control. For the best experience, please make sure you have the latest version of your browsers installed. -David, VSP

  • Information found was very informative.

  • I would very much like to win a pair of these glasses. I’m starting to show signs of macular degeneration.

  • Margo Duarte says:

    It won’t let me fill in required field. Have not heard of unity lenses

  • Beverly Ludwig says:

    I was recently at my eye doctor’s for new lenses. Why didn’t he tell me about blue light and its effects? I have already purchases new lenses and they were very expensive and I wouldn’t be able to afford another new pair that coreccts blue light.

    • David C. says:

      Hi Beverly, you eye doctor will typically ask questions about your lifestyle and habits and from there make a recommendation on any special type of lenses. Blue light filtering isn’t necessary for everyone but is typically a benefit to most. Even though you don’t have this option on your lenses now, please feel encouraged to ask your eye doctor about it in the future. -David, VSP

  • Sheila Dickens says:

    Great info

  • Jim Ervin says:

    The required dropdown box asking “Before today, had you heard of UNITY?” does not contain options and therefore I’m unable to enter the contest.

  • The entry would not allow me to select that I had heard of Unity Lenses. Therefore the entry would not submit.

  • Agnes says:

    Hello – Tried to submit an entry regarding the blue light filtering technology and had an issue. There is a question *Before today, had you heard of UNITY?* – three options are given but the drop-down is not working and there is no way to designate a choice. Thank you!

  • Jerry Cowan says:

    Send me my mini pad for x-mas

  • Jerry Cowan says:

    Send mt the mini pad for christmas

  • Glenn says:

    On the Unity web page that explains the types, the link for progressive is misspelled. Maybe someone at your site needs new lenses more than me.

  • mike toskey says:

    make your eyes smile

  • Meagan says:

    I recently got my daughter new glasses with the Unity Lenses, it’s only been a couple of weeks but she says they are good. The transitions work quicker with these than with the last set of lenses (fyi). Good Luck to everyone else 🙂

  • Judith Covey says:

    Helpful information. I use a computer at work and at home. I’d love to try blue flight filtering Unity lenses, especially on a new tablet. 🙂

  • TimoD says:

    My original comment has been awaiting moderation for 3 days now… what gives?!

    • David C. says:

      Hi Tim, sorry for the delay. We filter for spam quite aggressively and get a lot of comments. We take the time to respond to each one, which can back things up now and then. -David, VSP

  • Jeremiah says:

    This would be great for my daughters bday!

  • Melanie Johnson says:

    have you ever considered making something that could go right over the computer screen?

  • Gene says:

    I have not heard of this blue light before. I could use these glasses. I spend a lot of time in front of a computer screen at work. Thank you for this information.

  • Lisa golden-gee says:

    Looks like no one will get a chance to enter I too can not answer so it must not be compatable to VSP’s browser.

  • Dano says:

    I could use that ipad mini. It would go great with the progressive lenses. I like to work on cars and when I’m stuffed under the dash or undercarridge of a car, that Ipad mini would be real handy to view a video of what I’m working on, with out having to get out from under the vehicle.

  • Merlene Ryzak says:

    There was an issue asking if before had I heard of Unity. There is no where to put my answer. The indicator button is not working. Please let me know when this is corrected as I would like to enter. I accidentally dropped my glasses and there is a crack in my lens. Thanks.

  • loretta ledbetter says:

    How can i enter this contest when your form doesn’t let me answer all the questions. Specifically the yes/no question about Unity. Is this how you get away with not awarding prizes? Very unfair! I see others have had the same problem so its not the browser, its your form.

    • David C. says:

      Hi Loretta, it appears to be a browser issue. Please make sure you have the latest version of your browser installed. The blog does not support (without issue) some older platforms. -David, VSP

  • Dennis Clark says:

    I agree with Agnes… The drop down function asking if heard of Unity is not working. Must be a bug. Thanks!

  • Julian says:

    Thanks for the information. I’d never heard of blue light and its effects on the eyes.

  • Andrea says:

    can you give us some scientific medical sources to explain this harmful blue light phenomenon? i cannot seem to find anything about this on the internet. could this be just another gimmick to sell more crap on your glasses?

    • David C. says:

      Hi Andrea, fair question. You’ll want to look for academic studies, which are sometimes separate from traditional search results. One to read would be the Harvard Medical School’s “Blue light has a dark side.” Blue light isn’t a new phenomenon, but only recent lens technology has made it more socially acceptable to combat since the earlier models were bright orange goggles that looked silly. Hope that’s helpful information. -David, VSP

  • Henry Collins says:

    Great information! I never knew the risk!!!

  • Carol B says:

    I clicked “yes” that I’ve heard of Unity before & just want to let you know that you’re the reason I’d heard of them! Thanks for the chance! 🙂

  • Glenn H. says:

    Interesting article. I know I’m a little late, but I just saw this today. I know many glasses filter for ultra-violet light. How similar is blue-light to UV rays? How much do these ranges overlap?

    • Angelina F. says:

      Blue light is the next longest wavelength of radiation on the electromagnetic spectrum to UV – this means blue light has only slightly less energy than UV. The UV and Blue Light ranges don’t overlap – the blue light range begins right around where the UVA spectrum ends right on the short wavelength threshold of the visible light spectrum. Unlike UV however, blue light can penetrate all the way to the back of our eyes. The sun exposes us to UV and blue light wavelengths (one of the reasons that selecting sunglasses with good UV protection is important). When we are away from sunlight we are no longer exposed to UV rays, but many of the devices and screens we interact with every day emit blue light and we’re beginning to understand we need to protect our eyes from these wavelengths too. You could almost think of blue light protective lenses like Sharper Image TechShield like sunglasses for your screen!
