 Age
related Macular Disease (AMD) and macular degeneration can onset
from age 50, and is now known to affect 1 in 6 adults age >70
years in the USA and results in the reduction or loss of central
vision.
The causes of AMD are likely to be multi factorial, however, with
the rapid increase in the number of people developing it, research
has highlighted two important areas of concern:-
•
It is the loss of the antioxidant Lutein, in the
aging macula, which makes the retina susceptible to damage from
high energy visible blue light. Research showing that this is the
case, has lead to Retina International’s important recommendation
on sunglass protection for those with AMD and other retinal conditions
which suggests protecting the eye by using blue blocking filters.
•
Just like the skin, the eye contains a rich supply
of Melanin to protect itself. The function of retinal Melanin is
to absorb the high energy visible blue light. We lose Melanin as
we age, and this reduces the eyes capacity to absorb and therefore
protect itself from this blue light hazard, with a resulting increase
in retinal damage.
Due to this poor absorbance, the blue light scatters within the
eye causing glare and hazing which is both uncomfortable and reduces
contrast too.
| What
Can Medi-View Filters do to Help? |
Medi-View
filters are an ideal treatment for those with Macular Disease/Macular
Degeneration and age related night vision problems, as they address
these two essential requirements.
• To protect the eye from harmful high energy visible blue
light
• To reduce the symptoms of glare and increase contrast
How?
•
preventing
the exposure of the retina to the damaging effects of this light
•
performs
the vital role of blue light absorption, thereby stopping glare
and restoring contrast and definition.
•
Medi-View
filters exceed the recommendations made by Retina International
& block 100% UVA/UVB and all blue light.
| What
makes Medi-View filters better than regular sunglasses or photochromics? |
Regular tinted
sunglasses and photochromic lenses:
• do not eliminate blue light or therefore the cause of glare
for those with degenerative retinal disorders.
• reduce the transmission of all light waves across the spectrum
succeeding in making things simply ‘too dark’ while
still allowing through light that is problematic.
