Myopia

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%.

What is myopia ?

Myopia is a problem of refraction, the myopic subject sees badly from afar and very well up close . Everything happens for him as if he were looking through a magnifying glass. The image of a distant point is blurred for the myope, it is formed in front of the retina and not on it as in the case of the emmetropic eye (normal eye). As a result, the myope sees a spot and not a point!

On the other hand, when looking closely (without correction), the myope sees clearly without involving the accommodation reflex.
In the vast majority of cases, myopia is " axil ”, that is to say that she is the consequence of an eyeball that is too long (+ 23.5mm). It is more rarely due to a cornea that is too curved.
Myopia is often diagnosed young around 6 years old. The children read very closely, approach to look at the screens, squint their eyes to see in the distance... it often evolves until the age of 16 and stabilizes around 20-25 years . It can again evolve in women during pregnancy. Generally, the earlier it appears, the stronger it is. It varies according to environmental and hereditary factors.
Most often it affects both eyes and is little different between them.

It is often associated with astigmatism .

The word “ myope ” comes from the Greek muôps “who blinks to see better” and from the Latin myop, opis “who has low eyesight”.

Different degrees of myopia:

  • From 0.25 to 3.00 diopters : low myopia
  • From 3.25 to 6.75 diopters : medium myopia
  • Above 7.00 diopters : high myopia
  • Myopia greater than 20 diopters is rare.

The visual acuity of the myope is less than 10/10° with a Maximum sharpness distance at 5m . A myope of -0.50 diopters has an acuity of 5/10° and its maximum distance of clear vision is located at 2 m from its eye. That of a myope of -2.50 is 1/10° and its net viewing distance will be 40 cm from its eye . This distance will be all the closer as the myopia will be important. The highly myopic will have blurred vision beyond 10 cm , he cannot move around and practice his daily activities (sport, work, cooking, etc.) without being corrected.

From -0.50 diopters, driving is prohibited without correction ; wearing eyeglasses or contact lenses is compulsory without forgetting to have a pair of emergency glasses in your car!

tired eyes

1. Watch out for allergies

Do you have an allergic tendency? Every allergy sufferer knows that they cause itchy, watery and irritated skin. This reaction is caused by histamine, released by your allergen sensitivity. Histamine in the immune response causes the dilation of blood vessels and causes unforgiving itching in the nose, mouth or eyes that allergy sufferers know perfectly well.

The increased blood flow and itching caused by allergies can cause your eyelids to swell. This is how your red eyes are also puffy and tired.

For anyone sensitive to various pollens, it's best to try to work indoors and cover your eyes well with curved protective goggles (sun or anti-fog) . In any case, talk to your doctor who will advise you best.

2. Take breaks from your screens

Confinement, teleworking and the digital age are wreaking havoc on our visual health. Even though technological progress offers various advantages, the many hours spent in front of screens of all kinds weaken our eyes. The influx of blue light, proximity work are unnatural and cause headaches, dry eyes... Combining short breaks with your long hours of screen will help you relieve the genes linked to eye fatigue digital.

The famous 20-20-20 rule

The 20-20-20 rule is perfect for short breaks. Every 20 minutes in front of the screen, look up and look 20m outside (avoid other screens!) for 20 seconds. This 20-second pause allows the eye muscles to relax because the eye is in a rest position for distance vision.

If you can, feel free to relax in your chair or stand for a few moments. By closing your eyes, stretch your neck, your arms, your legs... A few yoga postures or a micro-nap for some and you will be fresh and efficient again in front of your computer without visual fatigue!

3. How about a compress?

Cucumber slices, tea bags or compresses? Grandmother's remedies still and always used to relax the eyes and take care of yourself.

Alternating hot and cold compresses is often discussed. The hot will relax the palpebral muscles while the cold compress will increase blood circulation This solution is certainly easy and effective to help overworked eyes but it remains temporary. It is important to identify the real cause of this eye fatigue : visual problem, poor correction, screen abuse...

4. Hydrate your eyes

Dry eye is also a major cause of your drowsy eyes. Dry eye or dry eye syndrome can come from many factors: diet, age, medication...

In front of the screens, we are absorbed and "forget" to blink. This step is crucial because it allows the hydration and lubrication of the cornea and other visual organs . Regularly and at each pause blink your eyes exaggeratedly. It's a natural, simple, and surefire way to keep our eyes moist and clean.

Do you not think about it or is it not enough? Opt for saline. A few drops in the eye will give you great relief. For some this will not be enough, in this case, consult your ophthalmologist who will prescribe adequate eye drops.

Above all, remember to drink plenty of water. In general, in the event of dehydration, the first organs affected are the eyes and the skin, which take on a dull and withered appearance. Proper water intake is beneficial not only for your eyes, but also for your health.

5. Check your eyesight

You have been wearing your corrective glasses for a long time and have not had a visual examination for 2-3 years. Chances are your prescription is outdated and the cause of your fatigue. In general , vision changes over time and your correction may no longer meet your current needs.

A comprehensive eye and sight exam is recommended every two years. An ophthalmologist or an eye care professional can assess your problems and find a solution: a vision prescription, orthoptic rehabilitation or other recommendations...

Have you ever worn corrective glasses? It is possible that your vision has changed, your visual fatigue can be a signal: your eyes are now tired because they need adapted glasses to see correctly. In any case, for more prevention and comfort, choose anti-reflective anti-blue light glasses .

To find out, go to an optician or ophthalmologist for an eye exam.

Reading problems? What if it was presbyopia?

Presbyopia, what is it?

As we age, we all experience annoying changes in our vision:

  • it becomes more difficult to concentrate
  • it is more and more difficult to see clearly on close objects .

Which mask to use in 2021?

For almost a year, wearing a mask has become normal to protect yourself from the coronavirus and now from its variants.

Faced with the shortage of masks, many have turned to their sewing machine to develop them by following the "AFNOR standards": no sagittal seam, 3 folds etc...

Then gradually came disposable masks, washable ones, surgical ones, FFP1, FFP2, UNS1, UNS2, cat1, cat2, KN95... a whole barbaric language for the average consumer! However, for the past few days, "homemade" or cat2 fabric masks have no longer been recommended or even "prohibited" in certain companies because they are not filtering enough.

mask-worn

What mask worn?

To deal with the different variants, three kinds of masks must be worn in the public space:

  • surgical masks: disposable paper masks, easily recognizable by their blue and white faces
  • FFP2 masks
  • UNS1 category 1 industrial fabric masks

Why wear one of these masks?

The level of protection just isn't the same. Indeed, a so-called category 2 handmade fabric mask has an average particle filtration rate of 70%, while a category 1 mask will have a filtration rate greater than or equal to 90%. This is why they are more protective.

Where to find UNS1 masks?

Simply on varionet.com!
