Risk Of Myopia From Blue Light Exposure In Teens

Similarly, blue and UV light exposure conferred a protective effect against myopia pro-gression with a concomitant increase in the reti-nal DA levels.132 However, the applicability of near UV and UV light to humans is limited due to the UV-blocking properties of the crystalline lens149,150 and...

Too much exposure to ultraviolet light from the sun increases the risks of eye diseases, including cataracts, growths on the eye, and cancer. We know less about blue light. Its effects are still being researched.

Blue light is being tested as a potential stimulant for retinal dopamine production (13) and has demonstrated a myopia-inhibiting effect (14).Short-term exposure to blue light shows an inhibitory effect on axial elongation in human eyes independent of defocus.

There are four key risk factors for a child becoming myopic, or being a pre-myope. These can be used in assessing risk of myopia onset: Family history - one myopic parent increases risk by three-fold, while two myopic parents doubles this risk again2.

hyperopic defocus, or electronic blue-light emission. Importantly, findings across all three models indicate that daily digital device use is positively associated with myopic risks, regardless of using weighted or unweighted exposure measures.

Light exposure influences non-visual functions such as circadian rhythm and emotional regulation via the visual pathway [3], and also has a profound impact on the onset and progression of myopia [142].
