Key points from article :
Mitochondria produce a molecule called adenosine triphosphate (ATP), the gas that fuels our cells.
As age increases, less ATP is produced, leading to decreased cellular functions.
ATP production by photoreceptor cells in the eye can drop up to 70 percent over a human lifespan.
Scientists investigating ways to improve mitochondrial function in the retina.
Prior animal research revealed mitochondrial functions, including amplifying ATP production.
They detected a 17 percent improvement in "Chroma Test" scores several hours after the red light exposure.
In older subjects the improvement was greater than 20 percent and the benefit was found to last at least one week.
Glen Jeffrey, lead author says "...recharges the energy system that has declined in the retina cells, rather like re-charging a battery".
In the near future, simple addition could transform eye care and vision around the world.
