Our latest blog is the story of the Bolle ESP coatings. 


How does it work and why is it worth having?


There has been a fair amount of information in the media lately about the damage that blue light can do to our eyes.


Firstly we should explain what blue light is.  Simply sunlight contains blue light.  Blue light, which is part of the visible light spectrum, reaches deeper into the eye and its cumulative effect can cause damage to the retina. Furthermore, in certain wavelengths, blue light is implicated in the development of age-related macular degeneration (AMD). The amount of exposure to blue light from sunlight varies, depending on the time of day, the location and the season.

Light is also essential for various functions. It helps us to see better, it helps us with our visual acuity and contrast acuity, it helps us perceive colours, and it helps with various non-visual functions of the body. For example, light helps to regulate our sleep/wake cycle, which in turn helps to maintain and regulate memory, mood and hormonal balance.

Research in France has indicated that the blue-violet light that is emitted from LED and Fluorescent lights can be tied to later development of Age Related Macular Degeneration.  This part of the visible light spectrum is emitted in high concentrations from our tablets, phones, computer screens and TV’s.

Now to be fair not all blue light is bad.  The blue light in the range of 465 – 495nm, is necessary for your eye’s pupil to work correctly.  It also helps regular our sleep/wake cycle.


So by this point you are probably waiting to read how to block the damaging blue light from penetrating your eyes.  This is where Bolle’s ESP (Extra Sensory Protection) lens coating come in.


It is an innovative lens coating system that reduces glare and harmful effects of blue light.
