H
ow many hours a day do
you spend in front of a
digital device? Screen time is
unavoidable for most of us these days,
which means that our eyes are being
bombarded at close range with
blue light.What is blue light?
Sunlight is the main source of blue light,
and some exposure is essential for
health. But there are many man-made
sources including our digital devices
such as laptops, TVs, mobiles and indoor
lighting. Modern living means we are
exposed to more unnatural blue light
than ever before; this, coupled with the
proximity of the light source to our eyes,
can cause problems.
Blue light is made up of harmful light
and beneficial light – blue light exposure
from the sun plays a critical role in our
sleep-wake cycle, but overexposure from
devices can cause digital eye strain and
impact our eye health.
Although research is needed to
determine how much natural and
man-made blue light is too much blue
light for the retina, our increased
exposure to blue light from screens is
enough of a concern that many eye-care
providers are investing in blue light-
blocking technologies that are
increasing in popularity.Helping your eyes
» Consider taking a supplement
containing lutein and zeaxanthin to
ensure you’re getting a daily dose of
these essential eye antioxidants.
» Eat plenty of leafy greens and brightly
coloured vegetables to provide vital
eye nutrients.
» Reduce the blue light setting of the
screens on your digital devices.
» Avoid looking at screens for at least
two hours before bed – this will help
your eyes as well as your sleep.
» Take regular screen breaks and look
away into the mid or far distance at
frequent intervals to rest the eyes.
» Blink consciously – blink slowly and
deliberately to help prevent dry eyes.
» Invest in blue light-blocking glasses.
These are available with either a
yellow-tint or anti-reflective coating to
reduce eye strain during prolonged
screen use.
» Purchase a blue light filter to go over
your screens.Blue light protection
The good news is our eyes have the
ability to absorb blue light and protect
against eye strain and damage.
To do this we need lutein and
zeaxanthin. These essential nutrients
are concentrated in the eye, where they
filter blue light and protect against freeradical damage. Lutein and zeaxanthin
do internally what sunglasses do
externally: protect the eyes against
light damage.
Lutein and zeaxanthin can’t be made
in the body so must be obtained from
our diet; however, studies show many of
us may not be getting as much as we
need to protect our eyes.

protect our eyes from overexposure
to blue light with a powerful
