BlueViolet Blocker

Blue light is part of our daylight and therefore a completely natural phenomenon. It helps keep us awake; however, in too great a quantity, it can have a harmful impact and cause tiredness of the eyes.

Due to the widespread use of LCD/LED monitors, LED TVs, smartphones, tablets, and energy-efficient lightbulbs (fluorescent lamps, LED bulbs) which emit large quantities of blue light, there have been various studies conducted regarding this. They revealed that blue light can negatively impact our eyes. To read more about the research carried out by Harvard Medical School, click here.

We have therefore decided to offer our customers an effective eye protection – the BlueViolet Blocker. Lenses with indexes of 1.61, 1.67 and 1.74 guarantee protection of up to wavelengths of 400nm whereas our BlueViolet Blocker lenses provide protection of up to 425nm.

The diagram shows how light is blocked. The red line graph indicates standard lenses that block only UV-light. The blue graph shows the BlueViolet Blocker lenses which also block harmful blue-violet light.

Benefits of the BlueViolet Blocker lenses:

  • The protection is in the material itself and not in the coating – sustainable protection
  • No strong antireflection – only a soft green reflection
  • Lenses are slightly darkened and therefore very comfortable to wear
  • Eyes are less tired after a long session using the computer
  • Have a refraction index of 1.50, 1.61 and 1.67

The lenses are for people who:

  • spend a lot of time on their computer
  • want to protect their eyes against blue light emitted by lighting
  • are sensitive to strong LED, halogen and xenon lights.

What else can you do for better eyesight?

  • Use dim red lights for night lights. Red light has the least power to shift circadian rhythm and suppress melatonin.
  • Avoid looking at bright screens beginning two to three hours before bed – or reduce the intensity of light.
  • If you work a night shift or use a lot of electronic devices at night, consider wearing blue-violet-blocking glasses.
  • Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.
