Do you know someone with a visual impairment? Are you trying to learn a little more about conditions for sight loss and how vision can be affected? VisonSim is a good start to discovering some of the ways people can be affected by sight loss.
Aipoly Vision and Tap Tap See do very similar things.
They are object recognise apps for visually impaired, to help someone understand their surroundings. You only need to point your phone or iPad at the object and press a large on-screen button to turn on the artificial intelligence. Brilliant for visually impaired and sighted who can use the app but also help improve it.
If you find you are using the Accessibility settings often or want to easily and quickly be able to make changes, you can include a link to it in the top bar of your mac screen. This post will quickly walk you through it.
