Pigmentosa is a genetic condition that mostly affects peripheral
An early symptom of Retinitis Pigmentosa can be night blindness,
where the loss of ‘contrast sensitive’ rods prevents
the eye from adapting to the dark.
Slow ‘dark adaptation’ occurs when moving in daylight
from bright to shady areas. The loss of greater numbers of these
‘brightness receptors’ diminishes the peripheral field
of vision, leaving just central or tunnel vision.
The retina becomes highly sensitive to glare, caused by the light
at the blue end of the spectrum. The discomfort and haze this causes
is one of the most commonly described symptoms with RP.
Can Medi-View Filters do to Help?
special combination of blue-bloc, 100% UV absorption and high contrast
pigments is used to create Medi-View filters and provide an effective
Retinitis Pigmentosa treatment.
The complete elimination of high frequency blue light waves, stops
the excessive glare & haze, while the addition of a high contrast
pigment increases colour definition and contrast.
By properly protecting the retina from the bleaching effect of blue
light, wearers also report faster adaptation when moving from sun
filters exceed the recommendations made by Retina International
& block 100% UVA/UVB and all blue light
makes Medi-View filters better than regular sunglasses or photochromics?
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.
