Glasses Against the Blue Light
Excessive screen exposure leads to headaches and even changes in circadian cycles.
When experts at the beginning of the 20th century were trying to figure out what significant advances the humans of the future would make, they rarely included anything like the Internet or smartphones in the equation.
Unfortunately, today, both digital natives (those confused generations between the millennial and the letter Z) and those who remember living in times without WiFi have no choice but to spend hours and hours glued to bright screens; sometimes, as a hobby, sometimes out of obligation.
We have the dubious honor of survival the first, in the long history of human beings, with a genuinely sitting lifestyle. Eight hours sitting in the office are mutual with long public transport trips looking at the mobile, to end the day by turning on Netflix or answering the WhatsApp of the friend you have promised to meet to catch up.
Some conditions, such as broken neck condition (neck pain caused by poor posture when using tablets or mobile phones), have made their appearance for the first time in our society.
As a journalist, you have to spend eight long hours (with one to eat) looking at the computer screen. When keep inspecting the cell phone, maybe it’s a chance, but most likely it has something to do with constant headaches, since many suffferef with serial migraines.
Thought would have to live like this all this life (first world problems and having been born at this time) until some colleagues from another section told me about the most revolutionary invention after penicillin: glasses against blue light, or, in other words, glasses for people who don’t really need glasses.
Studies have already shown by active and passive that spending many hours working in front of a screen causes adverse effects on the eyes. The first of these is the most common: myopia. Long-term use of short-distance vision with artificial light exacerbates this problem in children who already have a genetic predisposition.
Also, they cause eye fatigue (dry eyes, blurred vision, headaches). In other words, it is further natural for humans to spend the day running after mammoths to hunt them down and eat them advanced than looking at a screen and writing reports.
This is not a commercial space, so I will not talk about how excellent the glasses are. I will say that I went to an optician and had a little review.
They told me that I see well in general but that, inevitably, everyone, when they approach 30 years of age, usually gradually loses sight. I decided to buy the glasses because I also had nothing to lose.
How could it be otherwise? My co-workers issued all kinds of witty and mocking comments about it. “It is not scientifically proven that blue light is bad against the eyes,” a friend told me; even so, I thought that they could not do me bad either, so I use them (whenever I remember).
As much as my friend says, some scientists say that the influence of blue light can affect our sleep, inhibiting melatonin and altering circadian rhythms, in addition to all the eye problems that I have described above.
Probably on more than one occasion, it has been difficult for you to fall asleep after spending a long time looking at the screen of the tablet or mobile. To me, at least, yes.
Glasses are only a partial solution since the filter cannot be familiar; during the day, they are excessive and at night, insufficient
What the manufacturers say: the glasses not only protect against blue light but also sometimes against the sun’s rays. According to Ramón García, creator of the blog ‘Take care of your sight’: “It is not necessary to rely on an advertisement of fear, but it is essential to protect yourself from blue light.
As much as they tell you, computer glasses are not the best against it. It depends on the user’s profile. If you use the filter at night, it can make you more sleepy. It is best to use adjustable filters according to daylight.
According to the video that I include below, where he recommends the best glasses, the people indicated to use them are those who, like me. Do not have diopters but spend many hours in front of the computer and change devices a lot.
What do people think? Diving online, in general, there is a bit of everything. In Forocoches, Holy Grail of all existential doubts that may arise throughout the day. There are threads of all kinds, and some are several years old.
“When I am with the computer for many hours I no longer notice dizziness”; “I have a filter in my glasses, and the truth is that I do not notice any improvement” (wrong, dear user, they are not designed for that); “I notice that the whites are yellowish. Possibly the improvements come in the long term.”
And my personal experience? Well, in my case, my glasses are not bluish but transparent. So if I get a little information on the Internet. They seem to be for computers and have the filter in the lens mass itself. So they filter up to (approximately) 20% or 30% of blue light.
This means that it is a partial solution because they are excessive during the day. And insufficient at night since they are not adjustable. The most orange-colored glasses are the ones that could serve for that last-minute tired sight and regulate the circadian rhythm. But I have never seen anyone or offered them to me at the optician.
The bottom line is that maybe my colleagues were right because I haven’t noticed much after a month.
It is also true that I frequently forget them and that it is a bit absurd to use them during the day if you later come home and forget to. Put them on to keep looking at your mobile. Be that as it may, they have served to fulfill my childhood dream of wearing glasses. And I have found that it is practically impossible for them to stay dirt free.
And, above all, if they help filter even 20% of the blue light, welcome. Another option that remained advised in the optical review is, from time to time. Fix my eyes on a distant point on the horizon and rest it. And if all this is not enough, you can always lower the brightness of the screens. At least until we can go live like hermits, in a cabin in the country, away from the madding crowd.
