There are many of us today who spend long hours every day in front of a screen, whether for work or digital leisure pastimes. Computers, tablets, smartphones or connected watches all form a part of our daily visual environment. Unfortunately, the human eye was not naturally intended to work at such a close distance (40 cm to 1 metre) and for so long, with this kind of light source (LEDs). As a result there are many eye afflictions caused by both the harmful blue light from screens and the eye fatigue linked to excessive strain on the ciliary muscles

BLUE LIGHT FILTER
Blue light is a full time danger. It is emitted by ourcomputer smartphone or tablet screens and blue light is responsible for photo-chemical lesions to the retina. These lesions are irreversible and contribute to eyesight deterioration that may lead to blindness. Blue light also impacts our sleep pattern. The risks linked to prolongedexposure in front of screens are just as important as the onesfaced after exposition to UV light (AMD, cataracts).
Watching a screen can have plenty of troublesome effects on eyes, and on health in general. Red or irritated eyes, headaches (vision induced migraine) are typical symptoms of screen induced eye fatigue. This eye fatigue is a consequence of excessive strain on the ciliary muscles as to ensure focusing on-screen, our eyes place great demands on the ciliary muscles. Theprolonged contraction of these muscles for long periods is the primary cause of eye fatigue.Over the long term, this prolonged contraction tends to make the eye short sighted, i.e. cause far off vision to deteriorate even if it used to be fine.Over stressing the muscles may also trigger excessive ocular convergence between the two eyes, causing a slight diplopia double vision) or even a little squint.
Using an optical refraction phenomena, anti-fatigue technology causes light beams to converge on the eye's retina. The dioptric vergence brought to bear by our lenses limits the excessive eye strain and hence eye fatigue.The ciliary muscles are called on less so that they can retain their natural elasticity over the long term. The result is more comfortable screen vision and hence better concentration.
