Detecting vision problems at school

Detection of vision problems in children at school

At least 30% of primary school failures are due to late detection of vision problems . This is why for several years it has been proposed to the Minister of National Education, Higher Education and Research to set up screening campaigns in collaboration with optical professionals. The aim of this approach is to reduce the school failures of children.

Ophthalmological control in children

The ophthalmological examination is a health check that should not be overlooked for your child. According to Doctissimo , today approximately 620,000 children under the age of 6 in France have a sight problem and nearly 62,000 have not been detected. It is important to know that a sight problem can have very negative and serious consequences for the child if it is not corrected : loss of concentration, isolation, delay in reading, school failure 
In order to avoid these problems it is necessary to make an annual ophthalmological control to the child from the age of 3 years.

Screening campaigns in primary schools

Parents and educational teams do their best to ensure that children succeed in school, today there are school supports as well as AVS who can accompany children in great difficulty. However, late detection of vision problems is one of the leading causes of failure in primary education . This is why screening campaigns in schools are being discussed. We could soon see the first campaigns in the big cities.

Les aliments bons pour votre vue !

Foods that are good for your eyesight!

Good food for good eyesight!

makeup eyes

We think of paying attention to what we eat to improve nail growth or to have shiny and healthy hair, but our eyes are often neglected!

Yet they also require that we take care of (y)them , starting with what we put on our plates.

A good diet makes it possible to avoid all sorts of inconveniences due to certain deficiencies , such as AMD (age-related degeneration), glaucoma or quite simply to avoid worsening an already existing sight problem .

To begin with, a balanced and varied diet helps maintain a healthy overall lifestyle.

Here is our pick of the best foods for healthy eyes:


These are polyunsaturated fatty acids that are necessary for the proper functioning of the human body but that it cannot produce by itself. They must therefore be found in the foods we eat. They are present in large quantities in nuts, chia seeds, flax seeds, in shrimp and in fatty fish such as herring, salmon, sardines, etc.

omega 3 salmon

Vitamins A, B, C and E:

- Vitamin A is one of the molecules that make up the retina , it helps protect the cornea. It becomes very useful during conjunctivitis, glaucoma, cataracts or major vision problems , indeed a vitamin A deficiency would cause total blindness .

Vitamin A is found in calf's liver, carrots, broccoli, spinach...

- Vitamin B improves eyesight and prevents its decline , especially the "sub-vitamin" B2, riboflavin.

It is found in abundance in foods of animal origin such as cheese, eggs, meat or fish. It is also found in green vegetables such as spinach, asparagus or even in cereals or brewer's yeast.

- Vitamin C plays an important role in reducing the risk of cataracts and AMD . Indeed, the retina and the lens are bathed in a fluid with a very high vitamin C content . It is therefore necessary to ingest vitamin C to allow a good balance.

Vitamin C is easy to find in large quantities: in citrus fruits, red fruits such as blueberries or blackberries, broccoli, peppers...

- Vitamin E would have a protective effect against AMD and cataracts . It would reduce the progression of these disorders .

A daily dose of it by eating for example almonds, hazelnuts, sunflower seeds, avocados, etc. would provide protection against these diseases.


It is a very good element in the preservation of your sight and the good health of your eyes , it is found in cocoa, wheat germ, eggs, cashew nuts.

In order to have healthy eyes, integrating these foods into a balanced diet is the solution. When the good weather arrives, it is easy to find many fresh products rich in vitamins and minerals. It is also possible to take food supplements to complete a varied and balanced diet. But like everything, be careful with the doses taken, an overdose would cause negative side effects.

Foods to avoid:

A diet too rich in omega-6 including too many vegetable oils, seeds, eggs or certain meats would tend to cancel the effects of omega-3.

Processed foods of industrial origin which have little nutritional value and therefore no vitamins, minerals, necessary for the functioning of the body in general.

An unhealthy body will lead to vision problems as you age.

Anti-blue light treatment: COOL BLUE

A few words about blue light

Every day, we spend more time in front of various digital tools: at work on PCs, in the metro and transport with our phones or at home with the computer and tablets and all under LED lamps. The hours pass and we submit our eyes to blue light rays and parasitic reflections emitted by the screens; these cause many ailments (migraine, itchy eyes, back pain, etc.). According to numerous medical studies, these disorders come from the blue light HEV (High Energy Visible) which is emitted by the LED lights of digital screens. This blue light is the most harmful of the light spectrum and causes long-term damage to the eye and vision.

The problems of artificial light on the body

In addition to blurring vision and creating hard-to-manage ailments, blue light disrupts the sleep cycle. Indeed if you read on a tablet/reader in the evening before going to bed, it will prevent you from falling asleep, which will cause you: Difficult night, fatigue, irritability and difficulty concentrating the next day...

 The solution to fight effectively: The “Cool Blue” treatment

However, there are ways to reduce these harmful effects on our vision and our body and improve our well-being: reduce the use of our telephones, computer, television, tablet and equip ourselves with an accessory that will effectively fight against that harmful blue light.

Varionet opticians have understood that it is almost impossible to live without this technology which accompanies us and makes our daily life easier. That's why they developed the "Cool Blue" glass. Computer glasses equipped with this high-performance anti-reflective block artificial blue light from screens and UV rays. Thanks to its design, the Cool Blue™ anti-blue light glasses allow you to regain visual comfort and work in complete serenity.

You will find the Cool Blue™ treatment onrest glasses for 18-39 year olds or on reading glasses for presbyopes after 40-45 years old.

Visual problems: the first signs

View is one of 5 senses that govern human life, which is why it is important to take care of our eyes and learn to recognize the various vision problems and their induced symptoms. Here are some tips to help you spot these different signs.

blue light

There are 2 kinds of blue light : natural blue light emitted by the sun and artificial blue light emitted by LEDs (Visible Light Energy).

Solar blue light is one of the elements of the light spectrum; it is the light composed of UV and blue located at the border of the visible and the UV. This is not very harmful for a healthy eye and for wavelengths close to yellow even beneficial for our health.

On the other hand, artificial blue light is dangerous for the eye . We are all more and more confronted with it with technological development; this is the light emitted by a large number of everyday devices: PCs, flat screens, smartphones, tablets, tom-toms… and also by public and domestic lighting. Indeed, for economic and durability reasons, LEDs are replacing incandescent and halogen bulbs, etc.

All of these modern light sources emit a high proportion of blue light radiation called HEV (High Energy Visible).

Many studies have shown that even low sustained but repeated exposure is harmful; it is the cause of various visual disorders or genes such as tingling eyes, headaches and can also cause damage to the ocular annexes (lens, retina, eyelid, etc.) such as premature cataracts, AMD, etc.

The impacts of this light on humans are multiple because daily exposure to these devices not only damages our sight but also affects our circadian rhythm, that is to say our biological clock . These wavelengths of light stimulate the hormones of awakening and looking at your iPad, tablet or console at night can prevent you from falling asleep even when you are tired .

On the other hand, the strong stroboscopic effect (the large fluctuations in visually imperceptible light intensity) is the cause of glare .

The negative effects of LEDs are greater in children, the elderly, people undergoing photosensitizing medical treatment, aphakic people, etc.

This is why it is recommended to limit exposure to these light sources, especially among people most at risk and in the evening, then to protect yourself with specific anti-blue light glasses which protect your eyes from this radiation by absorbing a part of blue light .
