Astonishing Research Sheds Light On Exposure To Deep Red Hues For Improved Vision

brief interaction with the right light can improve the overall vision.

This one of its kind research stated that a maximum of 3 minutes exposure to a deep red shade of light every once a week might prove to be the right dose for eyesight improvement.


Initially started with flies and mice this research then quickly transferred to human participation. Prof Glen Jeffery said that “It does not really matter what the animal is or, to some extent, what the cell is, the light will impact.”

Having a wavelength of approx 670 nm the deep red light that was a main part of the research had a very specific hue.

He went on to further explain the process that lights commonly affect the mitochondria.

According to him, “These are highly conserved energy sources in cells — they are the cells’ batteries. The light increases the charge of the mitochondria and allows them to increase their energy output that has declined with age or disease.”

As we have witnessed that eyesight tends to get decline after the age of 40 and that is because of the reduction in ATP. Low levels of ATP mean that the cells do not have the right energy to carry out the activities properly.

Prof Jeffery said that “The great thing about the retina is that it has more mitochondria than any other organ because it uses so much energy. On top of this, you have easy optical access — you can direct light right onto retinal mitochondria, which you can’t do to mitochondria in the liver or the kidney. Add to this the fact that the retina ages faster than any other organ, and you can simply test its function by asking people what they see, and you have a perfect target for red light therapy.”

The key point of this research is that this exposure should be done in the morning. Because in the afternoon the results are not that promising as mitochondria get engaged in other types of cell activities.

Further studies are being conducted on bees to save them from the after-effects of hazardous insecticides.
