More on eyes

Another journal article has been published, with very promising results, especially if you have eye problems as a result of diabetes.

Macular oedema can develop in the eyes of people who have diabetes. It is a frightening thing and it has a deleterious effect in vision. Treatment can be unpleasant and isn’t guaranteed to improve vision or stop the deterioration over the longer term.

A research group in Singapore has recently published their work in an animal model of diabetic macular oedema. They used 670nm light, the dark red wavelength that has been shown to be effective in neurodegenerative disorders.

Link to the article abstract: here.

They found that this wavelength improved the function of the mitochondria in the retinal cells and this improved the health of the retina. They also found that there were no adverse side-effects.

They will be doing more research in this area, which is excellent. Meanwhile, they have reinforced other research that has shown that visible red 670nm can improve eye health.
