The myopic eye
Myopia is a visual abnormality identified since antiquity by Aristotle. This is refractive disorder more common in the world . Some ophthalmologists even speak of a global epidemic: according to a study conducted by the University of Canberra (Australia) 90% of young students in developed countries in Asia are myopic against 30% in the 70s. This phenomenon is found all over the world, in the USA the population of myopes has increased from 25 to 45%.
Undetected visual fault:
Many of us have a visual problem even sometimes without realizing it! For some, this visual deficit may be slight and following daily activities barely noticeable. On the other hand, for others, it is more important, but these people who have become accustomed to "seeing badly" think that they see well!
Extremely weak eyesight problems are common. The eye and brain get used to this deficiency, which is why the vast majority go uncorrected. But most of these people suffer from side effects: headaches, trouble concentrating, itchy eyes...
How do I know if I can't see well:
Here is a quick little test in which we will ask you a few simple questions to find out if you have excellent eyesight or if you should consult an ophthalmologist.
- A. When I drive, I see traffic signs
- From a distance, I have no problem.
- I have to wait a bit to see them clearly.
- I don't see them until I'm on their level, it's a big effort
- B. Reading a book or looking at the phone...:
- I can see it well at 35-40 cm.
- I have to get him away, it's hard for me to see him up close.
- I have to bring it close to my face to see it well.
- C. When I study or spend some time in front of a computer, when I read:
- I see well, but I get tired and often have headaches
- I see blurry, I tire very quickly and work requires a lot of effort.
- I have no problem seeing well.
- D. I watch television:
- Very close to see the screen well.
- I don't care, I can see pretty well from almost everywhere.
- I am not too far nor not too close.
- E. When doing precision work:
- Usually I have a headache.
- I have no difficulty seeing.
- I have trouble seeing up close.
- A. 1) 0 2) 2 3) 5
- B. 1) 0 2) -5 3) 5
- C. 1) 2 2) -5 3) 0
- D. 1) 5 2) 0 3) 2
- E. 1) - 2 2) 0 3) -5
Results: now add or subtract the points from each answer.
If the total is negative you have a tendency to farsightedness , ie you have difficulty seeing near objects. However, your eye manages to compensate for this problem, which causes headaches, eye fatigue and often difficulty concentrating.
If the total is positive you are certainly myopic ; people with myopia have difficulty seeing from afar and have excellent near vision.
Myopia, an epidemic
Myopia affects 40% of young people in Europe, in Asia it affects 90% of students at the end of their studies, alarming figures. Even if the genetic factor is important, the new lifestyle of young people indoors, in front of screens, leads us to believe that it is also one of the causes of this growth. Optometrists, doctors and researchers are increasingly interested in this subject, which they even call “an epidemic”.
Myopia, what is it?
Myopia is a vision disorder that causes blurry distance vision . This disorder is due to an excessive length of the eye and must be corrected by wearing glasses or contact lenses. Myopia stabilizes from the age of 20/25, once it is stable it is possible to undergo an operation to improve your quality of life by eliminating the wearing of glasses and/or contact lenses.
Environmental factors, major causes of myopia
Children and students are spending more time indoors than before. With the rise of the internet and consoles, they have never been so much in front of screens and sought close vision. A new way of life that has serious consequences on their health and eyesight. Indeed, practicing outdoor activities allows the eye to rest and exposes individuals to natural light . This releases dopamine, a neurotransmitter that stops the growth of the eye and therefore naturally fights myopia.
Protect yourself from myopia
In order to reduce the risk of myopia, it is important to encourage children to go out and play outdoors. It is necessary to curb indoor games that require a screen: TV, computer, tablet, smartphone because this artificial light increases the risk of myopia. For the youngest we offer Cool Blue + anti-blue light glasses , without correction they filter UV and harmful blue light thanks to their innovative material.
For students, the wearing of blue light blocking glasses to decrease the effects of harmful artificial light is necessary. From €39.00, we offer computer glasses with Cool blue anti-reflective treatment.
With the rise of social networks and the democratization of digital devices, the hours spent in front of screens have multiplied in just 7 years.
Indeed today a teenager spends an average of 6 hours in front of a screen per day . This digital generation is more than ever overexposed to harmful blue light and the damage is numerous;
- visual fatigue
- Blurred vision
- Headache (migraine)
- Dry and red eyes
- Increasingly difficult to see from afar,
This is called "student myopia", Varionet gives you the tips to correct this visual defect now!
