Digital era and eyestrain

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.
These are the blue light blocking glasses designed for the digital life, their innovative technology helps focus the eye's efforts when using digital devices.

With their blue light anti-reflection and their comfort correction or decreasing lenses for presbyopia, they are suitable for many users who experience :

  • Reduced eye strain , even with prolonged use of digital devices
  • Improved reading of small print.
  • Increased contrasts , high definition vision
  • Protection from the toxic effects of UV and blue-violet light

For children, the Cool Blue+ anti-blue light glasses are ideal for protecting their eyes; without correction they are suitable for all players!

We too, at Varionet, depending on our needs and ages, we use the Cool Blue computer glasses when we work because we spend long hours in front of our screens every day!

Buy prescription safety glasses

Why eye protection glasses?

For many activities, it is advisable to wear protective glasses: pruning, sanding, painting, welding... people without visual problems put on eye protectors without corrections easily. On the other hand, the others, generally, keep their glasses and damage them! Hence the interest of pre-assembled safety glasses for near vision presbyopes or Varionet prescription safety glasses.

All our safety glasses preserve your eyes and your sight from the dangers that surround you during your working days, at home during gardening or renovation work... In addition, our glasses are available with different types of treatment (sun, anti -fog, anti-reflective) and lenses (progressive, decreasing lenses, etc.)

Safety glasses are intended to protect workers' eyes . For these to be effective, they must be the right combination of ophthalmic lenses of adequate resistance, polycarbonate lenses and a frame with the aim of protecting the eyes in any situation. All meeting EN166FT CE safety standards

When they are used permanently by a person requiring a pair of glasses, they can be manufactured as safety glasses in view . Take into account that the obligation to wear glasses permanently in laboratories or in any position is very common, and this to require good vision and excellent protection.

Mid-distance glasses or proximity glasses

Degressive glasses, what are they?

Proximity glasses or degressive glasses come from a lens technology originating from progressive lenses; these glasses make it possible to offer more or less young presbyopes a clear multi-distance vision:

  • perfect near vision for reading and precision work
  • close vision for work on screen, to read sheet music for musicians...
  • intermediate vision to see your interlocutor or colleague correctly without taking off your glasses.

      These glasses are an innovation for 21st century presbyopes because they allow you to work comfortably in front of screens. The design of these lenses helps the wearer in his daily life by avoiding neck pain thanks to a more physiological head posture.

      Indeed progressive glasses are not the preferred equipment for working in front of a computer, you are obliged to adopt a head bearing resembling that of a "turtle". Opting for a pair of proximity glasses means opting for additional comfort.

      Presbyopia looking for visual comfort in front of screens

      Many new presbyopes who had no visual problem are reluctant to wear glasses with progressive lenses. Indeed they do not feel any discomfort for far vision activities such as sports, driving... their need is for near and intermediate vision . For them, rather than choosing basic single vision near vision lenses, it is smart to choose degressive glasses with these lenses specially designed for screen work and reading . These glasses, also called semi-progressive glasses by many ophthalmologists, allow the patient to adapt gently to the geometry of multi-distance lenses.

      Indeed, 60% of presbyopes use a computer and glasses that are not necessarily suitable for near vision. 75% of them experience visual fatigue after a day in front of the computer.

      Proximity glass is therefore preferred for people with presbyopia who spend many hours in front of a screen .

      Varionet proximity glasses

      Varionet degressive glasses contribute to your eye comfort and visual protection in front of screens: television, computer, smartphone, tablet, reader.

      MAVU opticians have developed a "Cool Blue" anti-blue light anti-reflective treatment which, via a filter, reduces the harmful effects of screens on the body: headaches, dry, red and itchy eyes, neck pain , loss of concentration at the end of the day…

      To try them is to adopt them; discover our eyewear collection with mid-length lenses !

        Visual protection at home

        The good weather is back and we are taking advantage of the weekends in May to garden, clear brush, do some DIY…

        Many traumas, shocks or eye injuries are counted each year and about 50% of them occur at home.

        Be safe also at home:

        For most of us, safety glasses or goggles are synonymous with the workplace; we think of certain professions in the chemical, agricultural, steel industries… and many mundane everyday tasks, such as mowing the lawn, the use of household products, seem to us without danger.

        A few tips to protect your eyes and those of your loved ones:

        • Use of protective glasses : wear standardized safety glasses appropriate to your visual needs and the tasks to be performed. These must protect you from wood chips, dust, chemicals, projectiles... and offer you a clear, sharp and precise vision. They can be solar or corrective for local work.
        • For tinkering, undertaking work, make sure you have good lighting
        • Remove debris before construction sites: for example, remove stones before mowing, these can be dangerous for you and for the people around, especially small children.
        • Properly store dangerous products and tools, taking care that they are not accessible to children.
        • Wash your hands well after using household products, phytosanitary products, etc.

        For easy and comfortable protection, we offer Varionet Safety glasses equipped with anti-blue light lenses or decreasing lenses for those over 40 . These protective glasses meet the EN 166 FT standard, they are made of polycarbonate and their lenses resist the impact of a steel ball 6 mm in diameter and 0.86 g launched at a speed of 45 m/s. Varionet Safety Pro goggles have an additional feature: high performance surface anti-fog .

        Let's not forget that we only have 2 eyes and that 80% of the information in our daily life comes from sight.

        In a few words to end:

        Always wear protective glasses for DIY, gardening, etc.

        Prohibit the youngest from dangerous games, crossbows, ball guns...

        In case of trauma, consult an ophthalmologist urgently and do not touch the damaged eye.

        Never lose your reading glasses again!

After 40 years, it appears and reading becomes progressively impossible hence the need to wear reading glasses . Most people with good vision misplace their reading glasses and have a collection of magnifying glasses all over the house!
