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!

Le port du masque est maintenant obligatoire dans de nombreux pays dont la France. Que ce soit dans les transports en commun, dans les lieux publics, les lycées le masque est devenu en peu de temps un élément essentiel de notre quotidien.

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.

Les lunettes rondes, oubliées depuis une vingtaine d’années, refont leur apparition. De nombreux fabricants et marques mode les ont remises au goût du jour dans leurs collections optique ou solaire.

corneal trauma

the corneal trauma is one of the main reasons for consultations with ophthalmologists in the emergency room. Do-it-yourselfers and "Sunday" gardeners generally do not protect their eyes before working and are the first to be affected by corneal trauma. There are also those who go down the ski slopes without goggles, those who receive a punch in the arcade and the reckless who uncork a bottle of champagne, paintball incidents... just as many situations that cause eye shock and damage the cornea.

Symptoms of Corneal Trauma

The pain is often immediate and very intense , it is this in general that informs the individual and leads him to the hospital or to a doctor. However it can happen that the pain occurs several hours later and often at night , such as during an ultraviolet burn. In these cases he is important to go to the CHU the nearest in order to have a precise medical opinion and to be treated by an expert in ophthalmology.

Prevention of corneal trauma

To protect your cornea, your eyes and also protect your sight, there are simple gestures such as wearing safety glasses or DIY glasses when practicing your activities. These protective glasses are available in eyeglasses , in sunglasses and glasses without correction . For those who are skiing there are the preferably sunglasses with polarized lenses . For a solar eclipse there are special category 14 lenses that protect your eyes.

The different treatments to cure corneal trauma

If it is a "classic" foreign body ; Dust, grain of sand… Just rinse his eyes with cold water .

If it is a chemical splash it's necessary rinse the eye with physiological serum for at least 15 minutes then consult an ophthalmologist afterwards even if you have no pain.

After a physical burn you don't have to do anything alone you have to immediately go to the university hospital to be handled by an expert. 

If you have just received a shock (punch) I don't have to rinse the eye or touch it, you have to close it and also go see a doctor.

In the most serious cases there is a corneal transplant !

Fitting the glasses

When you place an order for presbyopia glasses, rest glasses or prescription glasses on our website www.varionet.com, we check the frame and the lenses to see if there are any manufacturing problems: defective welding, damaged acetate plastic, surface treatment of the lenses, no scratches... Then we proceed with the assembly and then the shipment .



Glasses mounting procedure

– Pointing glasses : whether it is a decreasing lens or a rest lens, we will check, using a fronto-focusometer, that the power of the lens corresponds to your order or your prescription and mark the optical center of the lens.

– Frame probing : this operation is done with a probe which will be inserted in the bezel of the frame to scan the shape of the 2 circles on the right and on the left. For nylor or drilled frames, we will only feel the caliber of a lens.

– Centering and suction : the feeler is connected to a centering device on which the shape of the mount is displayed. We record the different parameters to be taken into account: client's pupillary distance, mounting height, type of lens, frame, type of grinding to be performed... we can thus position the lens correctly and suction it using a mounting suction cup and a double-sided sticker for trimming.

– Lens grinding : with a machine equipped with different wheels (one for each material) we proceed to the size of the lenses. All previously recorded data is transmitted to the machine. She checks that the diameter, the thickness of the glass allow this step. The glass will go over a roughing wheel and then over a finishing wheel with finer grains depending on its material.
Depending on the mount chosen, the grinding will not be the same:
- bevel for fully rimmed frames 
- creasing for semi-rim frames with nylon thread or metallic thread
- flat bevel for rimless frames
The lens is shaped like the frame.

– Counter-bevel : We make a counter-bevel with a hand finishing wheel. The goal is to break the edges of the glass so that it is not sharp and this avoids unsightly splinters.

– Assembly : The mounting of the lenses is different depending on the material of the eyeglasses:
- for plastic frames : we heat the glasses in order to soften the material and to be able to clip the glasses on it.
- for metal frames: we check that the curvature of the metal circle is identical to that of the lens and using a screwdriver, we open the frame to position the lenses.
- for nylon frames: with a plastic tab, we catch the nylon thread in order to insert it into the groove of the glass.
- for drilled frames: with a precision drill we drill the mounting holes and then we mount the branches and bridge with screwdriver, screw and nut with plastic chimneys.

- Verification : the assembly is finished, we iron the glasses on the focimeter in order to check the powers and the centering of the glasses.

- Repair : after mounting the frames are often a little deformed; it is a question of checking that the lenses are in the same plane, the temples and plates symmetrical, that the glasses close correctly.

- Cleaning : last operation to remove all fingerprints, marks on the glasses…

And here are your reading or resting glasses ready for delivery!
