It is unfortunate that with many eye conditions damage is
permanent and cannot be reversed. The key is prevention
but most people don't know what to look for at onset.
My idea is a 3D simulator (there would be a browser based
WebGL version as well as a Virtual Reality one) that would
let
people see through the eyes of someone with different
eye conditions. For example for glaucoma people's
peripheral vision goes first so in that simulation you'd see
the world through more of a tunnel (perhaps with rainbow
halos, that being a symptom of an acute episode). For
retinal detachment flashers and floaters would be
simulated (one would have to gather good data from
sufferers to make it as accurate as possible). For cataracts
things getting milky and halos could be shown. Every eye
condition could have a simulation and one could sample
every simulated condition to see if what they or someone
they loved were seeing matched it.
The technology has matured enough where one could do
this convincingly with the Unreal 4 engine or something
similar.

If you use a microscope after someone who needs glasses uses it without their glasses you get to experience how blurry their unglassesed world is. But in the other direction, I suppose. |

I think this idea could be adapted so that just like with a microscope, the screen could change focus to the point where people who need glasses can see the screen perfectly even though they never actually bought glasses because they are scared that needing glasses means you are old. And also they are cheap. |

Visual simulators are being developed.
So far the one's I've stumbled across center around visual snow and it's associated visual weirdness-es, They are not great to say the least. |

I will link to the one's I know of.

The kids need this to be able to explain to adults what they see.
Yes, I am very sure of this. |

"Use something on a computer screen to make glasses
unnecessary" is a common suggestion. Everyone who
suggests it seems to have not noticed that glasses have
custom-ground lenses in them, while screens do not. |
