EYECHARGER- bought the original model mail order from Australia years ago when they were selling the original model. It failed to be a clinical device for AMD due to regulatory reasons. Dr Jeffrey PhD now of Univ of London ( he formerly was in Australia and marketed it there) ) was interviewed by the AMD Brighthouse Foundation. Dr Jeffery's study found that in persons aged ~34 to 70 who did not have known ocular disease, a single 3-minute exposure to 670 nm (deep red) light in the morning (8-9 am) led to improved colour contrast sensitivity (vision of cones) by ~17% on average. 
• The improvement lasted up to a week in some participants for colour contrast. 
• The effect was timing-dependent: the same light exposure in the afternoon did not produce measurable improvement. The authors suggest mitochondrial “workload shifts” during the day may underlie this. 
• The mechanism proposed: photoreceptors (especially cones) have high mitochondrial density and energy demand; with aging, mitochondrial ATP production declines, impairing photoreceptor function. The deep red light is thought to “kick-start” mitochondrial energy production (via e.g., increased ATP synthesis, reduced mitochondrial viscosity, etc.).
Now the 6000 dollar in office red light treatment is different with stronger and different wavelengths.
I use my device daily. Most AMD sufferers don't believe in "home cures", the gut eye axis in AMD , supplements for AMD specifically shown in the research journal studies, exercise for retina health- but I do. Retina doctors don't study preventive measures and only offer AREDS2 and just say eat kale etc. There are so many factors that come together to make the perfect storm that becomes early AMD. It takes a multifactorial approach to attempt to keep it from progressing. I hope to hang in there with my intermediate dry stage until better solutions are found to manage it.
I believe in longevity devices and supplements because what other hope do we have!
