Spring is coming and with it beautiful flowers! these make the eyes happy for some but for others they are synonymous with eye irritation, dryness or allergies.

• What is an eye allergy?

eye allergy is a abnormal reaction happening at eye level. When in contact with an often foreign substance.

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

1. From a distance, I have no problem.
2. I have to wait a bit to see them clearly.
3. 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...:

1. I can see it well at 35-40 cm.
2. I have to get him away, it's hard for me to see him up close.
3. 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:

1. I see well, but I get tired and often have headaches
2. I see blurry, I tire very quickly and work requires a lot of effort.
3. I have no problem seeing well.

• D. I watch television:

1. Very close to see the screen well.
2. I don't care, I can see pretty well from almost everywhere.
3. I am not too far nor not too close.

• E. When doing precision work:

1. Usually I have a headache.
2. I have no difficulty seeing.
3. 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.

Wear glasses during a job interview

According to a study reported in the DailyMail , Wearing glasses during a job interview would increase the chances of getting the job . In fact, this is what at least 1/3 of the people questioned during the survey think: A third of UK adults think glasses make a person look more professional while 43% think they make people look smarter ".

What glasses should I wear if I have no correction?

Whether the recruiter likes it or not, the interview is often influenced by the first minute and the first picture. If you wear glasses, the employer will associate you with seriousness, attendance and trust.
If you don't have a sight problem, you can opt for glasses without lenses, as many Asians do, but you're not sure if you'll be taken seriously! The best solution is to go for blue light blocking glasses that will give you style and elegance . With a specific anti-reflective treatment and universal correction, they protect the eyes from the harmful blue light given off by the screens.

Glasses without correction

Non-prescription glasses will allow you to be your allies during your job interviews . If you are looking for a first job, an internship, an alternation and your physique rejuvenates you, do not hesitate to use them.

Cool Blue anti-reflective computer glasses

If you work on a computer or are confronted with screens all day, blue light blocking glasses are made for you. They you protect against the harmful blue light emitted by screens and ensure comfort and safety . You will be able to wear them for your job interview because they have only a very slight correction which will not bother you. You can then use them in everyday life to protect yourself from artificial blue light. In addition, thanks to their high-performance anti-reflective lenses, you can use them for night driving to protect you from the glare of headlights.

Good food for good eyesight!

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

Omega-3s:

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.

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.

Do you want to take part in the July 14 festivities by setting off fireworks or firecrackers? Don't overlook a few easy-to-apply security measures .

Indeed each year at this time, several explosion victims are received at the ophthalmological emergency room for ocular lesions which may be superficial but very painful. The most serious lesions can even create intraocular hemorrhages or severe contusion of the eyeball.

So what precautions should you take before setting off your own fireworks?

• Make sure that the fireworks purchased bear the CE mark.
• Make sure you have a clear space of at least 50m in diameter around the shooting area.
• Plant the rockets well in the ground, do not put them in bottles .
• Check that there are no electrical obstacles in the path of the projectiles.
• Install your spectators at a sufficient safety distance.
• Do not lean over explosives when firing and wearprotective eyewear .
• If one of them does not work, do not try to turn it back on. Sprinkle it with water.
• Never let children do the firing .

The aging of the eye, a subject that concerns us all!

Our tissues and organs age . Unfortunately, the eye does not escape this harsh reality. Today it is important to protect his eyes against the ultraviolet rays , blue light and for some infrared . The aging of the eye is a subject that concerns all individuals, it is necessary to have ophthalmological and optometric check-ups once a year.

The aging of the lens

The lens is simply the lens that sits inside the eye, just behind the iris (see diagram). This one deforms by pressure from the ciliary muscle. This deformation allows to have a clear vision, it is the accommodation. The lens becomes less and less flexible over the years and this leads to the symptom of “arms that are too short”, presbyopia.
After Presbyopia, it is the transparency of the lens which is reached, the crystalline lens becomes opacified especially with exposure to the sun and blue light: this is the cataract .

The aging of the retina

The retina and its central part, the macula , allows to see the details, it is what allows the individual to be able to read and recognize shapes and faces. The aging of this can be very disabling, this is called age-related macular degeneration: AMD

The aging of the optic nerve

The optic nerve is simply the " messenger », the one who will transmit the visual information from the eye directly to brain . With age there is a decrease in the number of nerve fibers originating from the retinal ganglion cells. This reduction in the fibers of the optic nerve is accelerated in the event of chronic glaucoma, a disease whose incidence increases with age.

Aging tear glands

The eye is permanently soaked with tears secreted by the lacrimal glands . The secretion of his tears decreases with age, which can lead to eye dryness .

Aging tear ducts

The tears are processed by lacrimal ducts to the nasal cavities. With age, these pathways can shrink and/or clog . This results in individuals with intermittent or permanent tearing. If this discomfort is too great then it is possible to go through the surgery .

Vitreous aging

The vitreous is a transparent and homogeneous gel inside the eye. With age, certain parts liquefy, condense... Which leads to the appearance of " flying flies 'or' flashes of light ".

Pixium Vision, the Iris project comes to fruition

A young French company, Pixium Vision has been bringing new perspectives to the visually impaired or blind for several years; indeed it will be able to help more than 4 million people through the Iris project. This consists of restoring part of the visual functions of the blind. in order to restore their sight. State-of-the-art technology that would allow blind patients to return to a "normal" life.

A great step forward for optics

With the project of making the view thanks to simple implants , the French company is revolutionizing the world of optics and brings real hope to these many patients with blindness. Pixium Vision has announced European approval for its artificial retina. Once this standard was validated by the European Union, the marketing of Iris quickly began. This new project has 3 times more electrodes than the first version, which would provide patients with vision as close to normal as possible. This week Pixium Vision successfully implanted and activated its Iris II bionic eye in a Spanish patient.

The new project of the French company Pixium Vision

The company does not stop there and is currently working on other projects in parallel such as Prima . This consists of the creation of a sub-retinal implant which would improve the sight of individuals suffering from age-related macular degeneration (AMD). Pixium Vision is also looking for solutions for patients with retinopathy pigmentosa.

Let's not forget that, whatever our age, it is important to protect ourselves from AMD, one of the causes of this visual disease: harmful artificial blue light given off by screens. So when you are in front of your computer, television, smartphone or even your tablet adopt the right gesture, wear a pair of sunglasses with a “Cool Blue” treatment.

Orthokeratology: Night lenses only

Corneal remodeling or Orthokeratology is an alternative to surgery for people with mild and moderate myopia and/or astigmatism . This practice is still uncommon in France but very widespread in Asian countries and even in the United States. Indeed, this one has already proven itself, it consists in reshaping the cornea via semi-rigid contact lenses which are worn only at night and which allow the patient to regain clear vision without equipment upon waking and throughout the day. .
However, it is essential to contact an ophthalmologist-contactologist trained in Orthokeratology to find out if your case is suitable for treatment.

How does corneal remodeling work?

Corneal remodeling consists of wearing semi-rigid lenses that have a particular shape during the night. By pressing on the cornea , they make it possible to correct vision without modifying the deeper cell layers. To benefit from this treatment, it is necessary that the sight is stabilized but there is no minimum age. However, it is mandatory to have good hygiene to avoid the risk of infection and irritation.

The risks of Orthokeratology

Like any treatment, there are several more or less dangerous risks:
- The lens can move during the night which would disturb the view the next day
– Eye infections and irritations if hygiene is not impeccable
– Have poor eyesight at night if the patient has to get up urgently (to take care of a baby, for example).

In order to avoid any problem, it is important to be followed by an ophthalmologist trained in Orthokeratology .

" Never two without three "

binocular vision of man is one of the most perfected in the animal world. Yet the 2-eye system may not have always guided human sight. Like all vertebrates, we have an epiphysis or pineal gland located between the two hemispheres of the brain which is the size of a pea .
According to some scholars, this epiphysis is all that remains of the third eye of our distant aquatic ancestors which would have calcified. It is possible that this useless third eye has acquired secretory functions over time. This gland secretes hormones regulating circadian rhythms (biological clock).
This third eye still exists in some animals. This epiphysis grows forward to form a median, single eye in the case of the shark or batrachians. In the lizard, it is a perfected eye with 5 layers of retinal cells and a macula.
Besides these biological notions, the third eye has an esoteric dimension. It is found in many Eastern civilizations (Buddhist, Taoist…), it is the psychic center other organs and allow meditation.

For Descartes, in the 17th century, it is "the seat of the soul"

The presence of a foreign body in the eye is a common thing. Whether walking, cycling, playing sports or simply shopping our eyes are exposed to dust and many other particles that can end up crossing the natural barrier of eyelashes and eyelids For irritate the eye .

This is why according to our activities it is necessary to wear sunglasses or some Protective glasses as a preventive measure.
