Blue light is present in daylight and is a completely natural phenomenon. It helps us stay awake, but at the same time, too much can also be harmful and cause eye fatigue.

Due to the widespread use of LCD / LED monitors, LED TVs, smartphones, tablets, energy-saving light bulbs (halogen lamps, LED bulbs) and xenon / LED car headlights that emit a lot of blue light, research has been done that revealed that blue light also harms the eyes. More on Harvard Medical School research.

That’s why we decided to offer users effective eye protection – BlueViolet Blocker. Conventional glasses with an index of 1.61, 1.67 and 1.74 have protection up to 400 nm. Our BlueViolet Blocker glasses have protection up to 425 nm.


  • the protection is in the lens material itself and not in the coating – the durability of the protection
  • there is no strong anti-reflective reflection – only a slight green reflection
  • the lenses are slightly tinted and are therefore very pleasant to use
  • eyes are less tired even after prolonged use of the computer
  • headlights reduce glare when driving at night
  • refractive index 1.50, 1.61 and 1.67


  • users who work a lot with a computer
  • users using digital devices (smartphones, tablets)
  • users who want to protect their eyes from the blue light emanating from the lighting
  • users bothered by powerful car LEDs and xenon headlights
