eye condition simulator

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.
