BLUE LIGHT
POTENTIALLY HARMFUL TO THE RETINA
As a part of visible light,
blue light passes through
the eye structure, reaching
the retina
17
BLUE LIGHT
POTENTIALLY HARMFUL TO THE RETINA
• Photochemical lesions
• Laboratory experiments show that exposure to blue light with a
maximum peak centered on 435+/- 20 nm can induce irreversible
cell death in the retinal pigment epithelium (RPE)
• Long term exposure has been linked to increased risk of
developing AMD
– AMD has a multifactorial pathogenesis

BLUE LIGHT SCATTERS
(Rayleigh Scattering)
Makes the sky blue.
Glare is caused by light scatter.
The result is visual discomfort and fatigue.

MEASURING HARMFUL BLUE LIGHT FILTERING
No industry standard
• Could be measured at a specific wavelength or calculated using
an average between a specific range

REFLECTIVE COATINGS
Blue light reflective properties can be
effective up to 20% or more

PROTECTION IS IMPORTANT
PUTTING IT INTO PRACTICE
Promote "sun protection" so that UV and blue light aren't
un-bundled as separate entities but lumped together
"I'm prescribing you Transitions lenses because they effectively protect your
eyes from harmful UV and short-wavelength light."
"Recent evidence shows that excessive blue light exposure may damage
your eyes, like UV light, and that is why I am prescribing you ______"
Adopt doctor-driven dispensing
