Screen glasses: myth or real protection?
In a world where we spend an average of more than 6 hours a day in front of a screen, the question keeps coming back: are screen glasses really useful or are they just a marketing argument? ? At Michils Opticians, we like to separate the true from the false, with pedagogy and elegance.
1. Where does screen-related visual fatigue come from?
Contrary to popular belief, it is not just blue light that strains the eyes. Screens intensely demand our near vision, which causes:
a decrease in blinking → dry eyes
a constant focus → accommodative fatigue
a prolonged exposure to blue light → visual discomfort
a fixed posture → cervical tension
Result: tingling, blurred vision, headaches, red eyes… a well-known cocktail for digital workers.
2. Blue light: danger or mere discomfort?
Blue light is not a “poison” for the eyes. But it can cause:
a glare
a sensation of discomfort
a disruption of sleep if late exposure
Studies show that the blue light from screens is much less intense than that of the sun. However, prolonged and close exposure can exacerbate visual fatigue.
Conclusion: blue light does not damage the eyes, but it can tire them.
3. Screen glasses, what do they really provide?
The so-called “blue light blocking” lenses are not a miracle solution, but they offer real comfort in several situations.
They reduce glare
The treatment filters out some of the wavelengths responsible for discomfort.
They improve contrast
Vision is softer, less strained.
They reduce visual fatigue
Especially for those working several hours a day on a computer.
They may improve sleep
By limiting exposure to blue light in the evening.
It’s not a gadget: it’s an additional visual comfort, especially for heavy screen users.
4. Who are they really useful for?
They are particularly recommended for:
people working more than 4 hours a day on screen
students
gamers
people sensitive to glare
those who regularly experience headaches at the end of the day
They are also very useful for wearers of progressive lenses, as they improve comfort in intermediate vision.
5. Myth or real protection?
Myth:
Screen glasses do not protect the retina and do not prevent eye diseases.
Real protection:
They reduce eye strain, improve comfort and can help you sleep better.
They are not essential for everyone, but they are truly beneficial for many.
6. The advice from Michils Opticians
At Michils Opticians, we recommend screen glasses based on your actual usage, not as a fashion statement.
We offer:
blue light blocking lenses
degressive lenses for work (ideal for the office)
custom solutions based on your posture, your profession and your prescription
Because every eye is unique, and every day in front of a screen is too.
Conclusion
Screen glasses are not a myth: they provide a real visual comfort, especially for intensive users. They do not replace an appropriate correction, but they can transform your digital daily life.
