Following the reconfinement and government requests, many are working from their living room or bedroom. This is how eyes are riveted on the various producers of blue light : telephone screen, computer, television... Staring at these screens all day can be harmful to our physical and mental health and to our eyes, essential organs of our body. our balance.

This is why it is essential to take care of your eyes in order to relieve the ocular stress and visual fatigue caused.

here are some simple tips to keep your eyes in top shape!

Don't clutter your eyes

This period of telework, even appreciated, is delicate for your eyeballs . By spending more time indoors and in front of screens, away from natural light, your eyes are under pressure. Digital visual fatigue appears, it is directly linked to the time spent in front of screens and blue light. Its symptoms are certainly not serious but they can be very annoying or even painful: headaches, blurred vision, itchy eyes...

A simple way to prevent them is the 20-20-20 rule : look 20 meters away for 20 seconds every 20 minutes! Rule valid for everyone from 4 to 99 years old with or without sight problems.

Wear blue light blocking glasses

Anti-blue light glasses or computer glasses are a simple and effective way to reduce the effects of digital eye strain.

Thanks to a filter, blue light blocking glasses block high energy visible blue light (HEV) . This is powered by digital screens. These glasses reduce visual discomfort and possible damage to the eyes.

Good to know : by blocking blue light, these computer glasses help you sleep better! Indeed, the brain interprets the brightness of screens as that of the sun...

Take care of your eyes while shopping

Even if outings are not authorized, we can still do our shopping. We must take advantage of this to choose good foods for our general state of health but also for our visual health.

In your basket, don't forget the carrots rich in vitamin A and at the top of the healthy foods for the eyes. More carrots? Opt for butternut squash, broccoli, sweet potatoes or spinach which are also super foods for vision.

To properly absorb vitamin A, zinc is necessary, and even more so during this period because it strengthens the immune system. You will find it in meat, nuts, beans or lentils.

Also don't neglect

- antioxidants : present in blueberries, artichokes or cocoa.

- omega-3s : you will find them in oily fish, salmon, herring, mackerel, cod liver oil or flaxseed oil.

- vitamin E : present in nuts, almonds, whole grains or spinach.

Stay fit for the future

Being alone all day at home generates a lot of frustration but it is an effective way to fight against contagion.

This is why it is important to take advantage of this isolation by taking care of yourself and your health for a more serene future. Every day realize that your eyes are fragile and very important organs for our general balance. Make new habits that you will stick with later. For example, why not do eye yoga in addition to your daily sport!

Blue light blocking glasses are the ideal protection for LED lighting; this ubiquitous lighting in our environment diffuses ray peaks of wavelength close to the color blue.

Good to know: the "traditional" artificial tungsten light mainly emitted red radiation.

Currently LED lighting is everywhere at home, in the office, in public places, as well as in digital devices: mobile phones, tablets, televisions, computers...

Is blue light harmful?

Many studies link LED lighting to altered circadian rhythms, which can negatively influence and weaken the immune system. It is also known that this light can inhibit the secretion of melatonin, which makes it difficult for us to sleep. LED lights are also believed to affect serious illnesses such as cardiovascular problems and certain types of cancer.

For your eyes, LED light can cause computer vision syndrome (CVS) or eyestrain . Visual fatigue can be caused by prolonged accommodation effort (the lens does not rest) and can occur in the following cases:

• We work in front of the computer screen or another digital device (mobile, tablet, etc.).
• We read for hours without a break.
• We perform actions that require great concentration such as driving.
• We are exposed to bright light: neon, led, sun.
• We are working in a place with insufficient lighting.
• We need prescription glasses but we don't use it!

This eye strain can cause other symptoms:

• Blurred and sometimes double vision.
• Headache, usually located in the temples.
• Dry eye
• Itching and burning eyes.
• Discomfort in the eyes when exposed to light.
• Concentration problems.
• Red eyes.
• Glare.

Therefore, eye strain generates symptoms that we associate with visual overstrain and lack of rest, but these inconveniences can also lead to other problems. Therefore, if they last, it is better to consult an ophthalmologist.

Blue light glasses then?

To protect our eyes from the possible harmful effects of blue light, anti-blue light glasses with specific protection filters for this type of lighting have been developed, their purpose? Reduce the intensity of blue radiation and UV. It is a simple and effective way for more visual comfort.

Varionet opticians offer you blue light blocking glasses without prescription for children or those under 40 without visual defect as well as computer glasses for presbyopia after 40 years.

Work, re-entry and eyestrain

The month of September is here, synonymous with back to school and this is a sign that the holidays are beautiful and well over! Summer is coming to an end and autumn is on its way. We have to adapt to the days that are getting shorter and it is common for eyestrain to appear. No more idleness, little naps, the daily routine is back with the long hours spent in front of digital devices and paperwork. Screens, close work can affect sight but not only; indeed your vision can also be weakened after the summer if no precautions have been taken against the sun (cap, sunglasses, etc.)

What are visual genes during recovery?

Visual fatigue and dry eyes are the most common damage occurring after several hours in front of the computer .

Staring at the computer screen for a long time reduces blinking and thus the production of tears causing dry eyes , the feeling of sand in the eyes...

Visual fatigue is generated by overexertion of the eye muscles over a long period of time . We could compare this effort to a marathon, in which case we understand that we can be tired! Visual fatigue is manifested by itchy eyes or burning sensations. Often the eyes redden and the vision becomes blurred. Added to this are regular headaches, neck pain, dizziness....

Some tips to avoid eye strain

Here are some suggestions to better understand the return to work and visual fatigue:

• Place your screen at the correct distance, ensuring that it is at eye level.
• Feel free to increase the font size, your eyes will strain less
• Take a break without a mobile by looking as far as possible, take the opportunity to drink a coffee, a tea, do eye yoga
• Blink regularly, moisturize your conjunctiva with saline to avoid dryness, and don't rub your eyes.
• work in a bright place with natural light.
• Schedule an eye exam with your ophthalmologist, eyestrain can be a sign of presbyopia .
• Wear blue- blocking glasses equipped with rest lenses for emmetropes or with the appropriate correction according to your needs.

Back to school is coming and your eyes are already tired!

Why?

The lights follow each other and are not alike: after refueling with vitamin A in the sun, the rays of blue light emitted by your computer , smartphone and other digital devices arrive.

Blue light , everyone talks about it; it is present everywhere! First of all in the natural light emitted by the sun , in this case a "normal" exposure is strongly recommended for its beneficial effects for humans. The so-called "blue-turquoise" light helps with falling asleep, with the proper functioning of the circadian rhythm... Conversely, "blue-violet" light plays the opposite role and has harmful effects on your eyes.

After good sunbathing, you are faced with screens, LEDs that emit a large amount of blue-violet rays. This exposure associated with the short viewing distance of the different media causes eye fatigue as well as many genes:

• burning eyes, dry eyes
• blurred vision
• retinal damage in children
• difficulty concentrating
• headaches, neck pains...

The solution? Blue light blocking glasses

After sunglasses, blue light blocking glasses are the solution. Blue light being everywhere, they are the essential accessory to reduce the harmful effects of screens. Many ophthalmologists such as Doctor Jean Leid recommend wearing anti-blue light glasses in order to protect and preserve your eyes, these absorb nearly 30% of blue-violet rays and 100% of UV rays.

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.

Why Buy Anti-Glare Glasses?

Anti-reflective lens technology helps eliminate light reflections that interfere with vision . Light sources, whether natural or artificial, cause reflections on the glasses which can be uncomfortable for our eyes, reduce the quality of our vision and are disturbing for our interlocutor who sees himself as in a mirror...

As such, a survey conducted on visual health shows that 75 to 80% of spectacle wearers prefer to wear anti-reflective glasses. However, only 58% are willing to bear the additional cost of these treatments.

Certainly, if they were better informed about the advantages of this type of glasses, they would bet on this purchase, since the visual quality will ostensibly improve.

What are the benefits of anti-reflective glasses?

• They reduce eyestrain and avoid problems such as itchy eyes, red eyes, itching...
• Unlike simple glasses, scratches, micro-scratches occur less.
• They improve the contrast: the colors, the contours are clearer.
• They make the glasses easier to clean. Most treatments usually incorporate a hydrophobic and dirt-repellent filter. Thus , the droplets are less annoying.
• They reduce reflections and glare during night driving caused by other cars' headlights, as well as ambient lighting. With anti-glare more safe driving! Remember that 90% of the information we use while driving comes from vision. It is therefore essential that they are as perfect as possible.
• They eliminate almost all reflections (up to 99%). Thus, they are more transparent not only for the user, but also for the interlocutor. 
• If you work in front of a computer, choose blue light blocking glasses . Their specific treatment will eliminate screen reflections, protect your eyes from the harmful effects of blue light and allow you to be more efficient. Some errors may be due to thoughts that trouble us for reading and especially less fatigue at the end of the day.

And a downside: the price?

The only downside is the price, as these glasses are a bit more expensive than the basic ones. Even so, it is worth choosing a less expensive frame and investing in anti-reflective lenses that will undoubtedly improve our visual quality and ocular comfort .

On Varionet we offer you for only 30€ extra on all our reading glasses * a powerful anti-reflective anti-blue light treatment.

* except pre-mounted glasses

As we have already seen previously, the digital world in which we live demands a little more of our sight every day to the detriment of the other senses. This causes visual fatigue and other inconveniences.

Young people under 30 and especially children are the most vulnerable, 3/4 of them experience different symptoms of digital visual fatigue.
A person's risk of digital eyestrain is determined by how often and for how long they use these digital devices.
The simultaneous use of several devices and the proximity of these becomes a key element.
Computers, tablets and smartphones are the cause of this type of fatigue due to the emission of blue light, which penetrates the eye more intensely than other wavelengths .
Numerous studies confirm that the wavelength of blue light affects concentration and attention during the day. And it can cause a sudden disruption of sleep at night, these alterations are associated with an increasing vulnerability to chronic diseases.

Practical advice:

• The 20/20 rule: every 20 minutes you spend in front of the screen, take a 20 second break while looking at least six meters away
• Avoid glare on screens , which dazzle the eyes and cause visual fatigue Arrange your workspace as well as possible.
• Stretch your arm to calculate the optimal distance from the computer screen : the palm of your hand should touch your screen.
• Wear blue-blocking glasses: These glasses have anti- reflective coating applied to the lenses that selectively filters out harmful blue-violet light emitted by screens. Cool Blue computer glasses reduce glare, improve contrast and help prevent premature aging of the eye , because our eyes are not designed or ready to spend so many hours in front of screens.

Why choose Cool Blue blue light glasses?

These blue light glasses are the effective solution for people who use screens for several hours a day and notice visual fatigue.

Tips for visual well-being for a good start to the student year.

Is your visual well-being the sine qua non of your student success? Here are some tips to get your school year off to a good start.

Prepare your visual well-being before the start of the school year

It's never too late to go to the ophthalmologist to check if you need prescription glasses or simple glasses . Visual well-being depends on it. Whether you already wear glasses or the need arises, the ophthalmologist will make an adequate assessment and decide whether to make a correction. An appointment with the ophthalmologist before the start of the school year allows you to be certain about your eyesight and to start your year off right.

Adopt anti-blue light computer glasses for your visual comfort

Anti-blue light glasses help relieve the eyes when they are exposed to natural or artificial light sources. Your main work tool being the computer, it emits a tiring light source for your eyes (blue light) and can be a factor in the progressive deterioration of your eyesight.
Resting glasses in front of screens or when working with classic tools such as manuals can prevent or radically slow down this deterioration. It also helps to avoid headaches, common among students. Eyeglasses are the best allies for students who want to pass their exams, good eyesight promoting concentration and learning.

Get away from screens before the start of the school year

Computer screens and particularly those of smartphones are becoming miniaturized. Students complaining of visual fatigue are more and more numerous and the number of myopes increases with near vision always more solicited. In order to avoid vision problems when you come back to school, give yourself one or two days off a week away from screens. Don't stare at your screen for hours, take breaks every hour.

Remember to moisten your eyes

Facing the screens, during work that requires a lot of attention, students often forget to blink or blink much less with all the consequences that can result from this, such as dry eyes, visual discomfort or even the feeling of having bad vision.
Remember to blink enough to moisten them. Ocular surfaces that have a larger diameter are sometimes less easy to moisten than surfaces with a smaller diameter, even with enough blinking. In this case, you can obtain artificial tears by consulting your ophthalmologist beforehand or simply physiological saline.

Adapt your lighting and equipment

The lighting in the room must be of the same intensity as that of the screen. It is best to arrange your work desk perpendicular to the window. Avoid working in the dark. Opt for an anti-glare screen. Your office chair must be high enough to preserve the neck.

Welcome back everyone!

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.
