Light grants us sight and the ability to perceive colour, but part of
it can be harmful to our vision.

Harmful light is composed of both invisible UV rays and visible blue-violet light that are emitted
by several sources indoors and outdoors.



  • Children’s crystalline lenses let through
    6x more harmful radiation than the adults.1
  • 30 % of adults spend 9 + hours
    on a digital device every day.2
  • LED is estimated to account for
    84% of all lighting sources by 2020.3


The flickering and glaring caused by short-term exposure to harmful blue light may be one of the reasons for eyestrain, headaches, physical and mental fatigue.


In the long-term, UV and blue-violet light, reaching the eyes’ front and back internal tissues, are a contributing factor to eye diseases such as cataracts and age-related macular degeneration. These diseases are the two leading causes of vision loss in adults over the age of 50.5

With an aging population and increasing life expectancy, the occurrence of cataracts and amd will be multiplied by 2 in 30 years.4

It’s important to protect vision from a very early age, all life long. Eye protection should
