One thing that almost everyone experiences as they age is a decline in their vision, although a new study in the Journals of Gerontology reveals that this problem may have a surprisingly simple and affordable solution. By staring at a deep red light for just 3 minutes a day, older participants were able to significantly improve their vision.

The human retina contains two kinds of photoreceptor cells, known as rods and cones because of their respective shapes. Rods are found around the boundary of the retina and provide us with peripheral vision while also helping us see in low light conditions, while cones give us color vision.

Both types of cell have high energy demands, and receive this energy in the form of a compound called adenosine triphosphate (ATP), which is produced by their mitochondria. However, from the age of about 40 onwards, our mitochondria begin to function less efficiently, meaning less energy is available for our rods and cones and our vision subsequently starts to deteriorate.

Long-wavelength light spanning 650 to 1,000 nanometers – which has a deep red color – has previously been found to improve mitochondrial performance, which is why the study authors decided to investigate whether this could be used to restore vision in older people.

Seems a device is required wonder how red it needs to be could you generate a sufficient red on a decent monitor

Kewlies. You can do this while waiting at the traffic lights.😁

yeah they’ve been doing far red light healing studies for ages, agree interesting

Hmm, doesn’t look like I’ll be throwing my glasses away after all.

I had to drag up the words. Check “chromotherapy” and “syntonics”.

This recent stuff is a bit different, but I’m still skeptical.

I’ve been trying to buy prescription rose coloured glasses for ages.

I had the option to buy some once when I was a teenager and turned them down, and have regretted not buying them ever since.

For a red-green colour blind person, the world appears much bluer than for normal vision. That isn’t an advantage. Rose coloured glasses would definitely help.

After 3 minutes you look around and everything looks blue

I’ve had my computer screen set to low-blue for about a decade now.

Apparently, rose-coloured glasses are available on the web. I’ll look into it next time I need a new pair.

Even if I assume you are telling the truth, your description of your experience is based on your experience, so it may be quite misleading from my experience.

But that doesn’t mean that the way any individual experiences that independent reality is the same as anybody else’s.

There is no reason (that I know of) to suppose that our experience of the colour red (for instance) is different, but if it is, I don’t know how that could be determined.

our experience of “the colour red” in English is completely different to the Russian experience of “the colour red” and yet it is indistinguishable from their experience of “красный цвет” in Russian somehow

essentially people get acquainted with their processing, representational conversion products of the wetware, that’s the primary thing people experience, people experience what their brain does

across the species great commonality might be assumed, and much of it where difference exists is converged by assuming sameness, which is a mixed bag in itself, the assumptions have products from, variously there are forces inclining sameness, some constraining, and some working against

of the extent a person might experience what other minds experience, nobody can too exactly, which is not a bad thing at all, the differences in some ways is like the physical spaces between things, and not entirely unrelated

consider a world of increasing interconnectedness, what might be lost, as the spaces are closed, as the assumptions of sameness become more and nearer, and everywhere

That’s an example of it, yes.

But you’re right: language has nothing, and yet has everything, to do with it.
