By this point in our lives, we're all aware of the potential harm the sun's rays can have on our skin health. The invisible ultraviolet rays that radiate down on us can reach deep beneath the skin's surface, burning our skin and damaging our cells. Taking precautions while in the sun is a good habit to develop. We're talking SPF 30+, wide-brimmed hats and beach umbrellas. But should this habit also translate to screen time?
The Blue Light Breakdown
The topic of blue light and its effects on our eye health is a popular one. There's documented research that excess exposure of blue light can directly impact our eyesight. Because of this knowledge, you can now purchase cellphone screen-protectors with blue light filters. Additionally, most eye-glass companies will also offer blue light upgrades to the lenses of your glasses. But what about the impact of blue light and our skin health? Could it be possible that our digital screens are slowly damaging our skin? Well, we just don't know... Yet.
There is some evidence to suggest that blue light can induce photoageing but the long-term studies just aren't ready. But despite the research being less than conclusive, utilizing filtered screen protectors doesn't do you any harm. And if anything, limiting your screen time late at night will help improve your beauty rest and we're all about that life.
Hi Susan! What a great question. We would only assume that the digital screens in the 70s would also emit blue light. Unfortunately, we do not have a conclusive answer for this since there still isn’t enough data to support that the blue light is causing an impact.
That being said, as technologies evolve, we’d assume the screens today are better designed in our favour (fingerscrossed!). Remember, everything in moderation. It’s always a good idea to make the conscious effort to lessen the amount of screen time, daily.
I have used computer screens since 1976. Did they have blue light then and was it a different intensity then the blue light today?
