How to protect your eyes from harmful blue light and UV?

We all know about the damage caused by the sun, but what about the light emanating from your devices? Blue light is a part of the artificial light spectrum emitted by the LED screens around us. Like the one, you’re on right now. You should add another worry to the list because it turns out the screens you use for work, fun, and entertainment are aging you and your hair. Not to be a total bearer of bad news—we don’t need to wait for Elon Musk to invent the phone that implants into your brain to eliminate the blue light issue. You can take protective measures against this and just unplug it. Like, even if it’s just for a few minutes that you gradually build up, there are about a million reasons to distance yourself from your devices.

How Do Blue Light Blocking Glasses Work? 

No matter how old you are, it makes common sense that spending a ton of time in front of a screen isn’t the best idea. With the rampant rise in screen time during the COVID-19 pandemic, many people have become more aware of the blue light those screens emit and how it might affect the eyes. 

So how do blue light glasses work in your favor? Blue light-blocking glasses are just what they sound like. They’re glasses made with special blue light lenses designed to filter out blue light, but let other types of light through. The idea is to protect your eyes from the high-energy blue wavelengths, reducing the potential for eye damage from prolonged exposure.


Note that glasses treated against blue light have a more or less yellowed filter depending on the degree of filtering. By removing your protective glasses, you will see for a few moments the life in blue with sometimes some glare. Depending on your use and your sensitivity – there is often a period of adaptation, the first day can seem unpleasant: eye fatigue, headaches or even nausea (rarely).




You have to wait a few days to obtain benefits, which vary greatly depending on people:

-An improvement in sleep (less insomnia, faster falling asleep) and therefore a reduction in general fatigue

-A decrease in tension/pressure in the eyes at the end of the day, the feeling of having more rested eyes.

-Sometimes a decrease in tingling or ophthalmic migraines.


Who Should Wear Blue Light Protection Glasses?  

Even though there are still uncertainties surrounding the effects of blue light today, children, people predisposed to AMD, and heavy screen consumers – including those who do not need corrective lenses – will be able to ” equip with an anti-blue light filter in order to feel reassured.
