Do you work on a
computer all day? Lutein and zeaxanthin are in the retina and protect our eyes
from blue light emitted by our technology devices.
Computers, laptops, tablets and smartphones all emit high
amounts of blue light.
Blue light (short wavelength visible light) causes oxidative
stress to the retina. This will have a
particular effect on people with less of the macular pigments lutein and
zeaxanthin. People with light coloured irides, people with AMD, and people with
a genetic predisposition to AMD are more susceptible to the harmful effects of
blur light.
In addition to damage to the retina, blue light also causes
glare and eye fatigue. Protect your eyes from blue light by wearing glasses
that filter.
Lutein and zeaxanthin are pigments that found in the macula
(the central part of the retina). Our bodies can not make lutein and zeaxanthin
and so we must obtain them from our diet.
Lutein and zeaxanthin act to absorb blue and UV light which protects the
macular from their harmful effects.
Kale, and dark leafy greens are a great source of lutein and
zeaxanthin, with Kale being the top Eyefood for eye nutrients.
A diet high in lutein and zeaxanthin can improve vision in
those with age related macular degeneration and also protect against it.
If you use technology devices often you should also consider
asking your optometrist about blue blocking lenses for added vision protection.
