LED light can damage eyes, health authority warns
"The "blue light" in LED lighting can damage the eye's retina and disturb
natural sleep rhythms, France's government-run health watchdog said
this week. New findings confirm earlier concerns that "exposure to an intense and
powerful [LED] light is 'photo-toxic' and can lead to irreversible loss
of retinal cells and diminished sharpness of vision."
While less dangerous, even chronic exposure can "accelerate the ageing of retinal tissue, contributing to a decline in visual acuity and certain degenerative diseases such as age-related macular degeneration," the agency concluded.
LED cellphone, tablet and laptop screens do not pose a risk of eye
damage because their luminosity is very low compared to other types of
lighting, Francine Behar-Cohen, an ophthalmologist and head of the
expert group that conducted the review, told journalists."
Better Vision for Patients with Albinism - Brian Brooks, NIH Clinician Scientist
A study performed on mice showed that if they had albinism and had a little tyrosinase in their blood, administration of the drug nitisinone caused their fur and eyes to become more pigmented. Improvement in vision can be detected in mice within one month of this treatment.
Nitisinone increases melanin in people with albinism
"A small pilot clinical study at the National Eye Institute (NEI)
suggests that the drug nitisinone increases melanin production in some
people with oculocutaneous albinism type 1B (OCA-1B), a rare genetic
disease that causes pale skin and hair and poor vision. Increased
melanin could help protect people with the condition against the sun’s
UV rays and promote the development of normal vision. Study results were
published in JCI Insight. NEI is part of the National Institutes of
Health (NIH)."
How to Cook Eggs for Maximum Antioxidant Nutrients
In this video by Dr Eric Berg, he discusses how certain antioxidants found in eggs, lutein and zeaxanthin, are important for health- particularly eye health (and liver and brain health as well). They particularly accumulate in the retina and lens of the eye and protect against Age-Related Macular Degeneration and Cataracts. They also limit blue light exposure by absorbing that wavelength of light. Blue lights are also damaging to the eyes. These two nutrients can also be found in vegetables, shrimp, lobster, salmon, avocado, and egg yolks. Eggs should be organic and pasture-raised. They can be damaged or destroyed by excessive heat so it is important to cook the eggs gently and with no excess heat. Ideally the yolks should be runny, as in poached eggs or fried eggs sunny side up. Additionally, omega-6 fatty acids are pro-inflammatory and if eaten in excess can contribute significantly to damage to the eyes, so reducing consumption of those oils is also important. They are found in vegetable oils such as corn oil, soy oil, and canola oil.
