Blue light makes you age: How to turn down the blue light on your devices

Have you ever gotten a headache from staring at a computer or TV screen for too long? This may be because of the blue light exposure from the various screens we look at all-day, which may cause eye damage. While scientific research on the long-term damage isn’t yet clear, if you stare at blue light screens too long you may experience symptoms such as blurry vision or dry eyes.

 

But what if we told you that blue light may make you age faster? According to a recent study done using blue light on flies, chronic blue light exposure can lead to premature aging. Blue light may have subtle effects on cells like your skin or subcutaneous fat.

We have the solutions to help turn down the blue light on the screens you use every day so you can continue using and watching your devices without causing aging or harm to your eyes.

I turned down the blue on my clock-radio display by remembering my experience with black and white photography 60 years ago. The way to darken skies for more contrast was to use a yellow filter, such as Wratten K-2. I got a sheet of flexible transparent yellow plastic at an art supply store and cut a small piece to tape on the clock-radio. Perfect, easy, and cheap ($5 or so).
