This application simulates symptoms of low vision vision. It can reproduce blur, glare, tunnel vision, central scotoma and nystagmus. It can also simulate complex situations such as glare and tunnel vision at the same time. It allows users to share their low-vision settings and take photos and videos during the simulation.
There are other similar applications, but the features of this application are that it allows users to take photos and videos during the simulation and to record audio of what they feel during the experience.
To adjust effects, tap "Effects" on the top screen. Tap "Effects" again to close the adjustment screen.
Use the sliders to change the values for blur, glare, tunnel, scotoma and nystagmus to simulate the view of low vision. Tap "Glare" or "Nystagmus" for more detailed adjustment.
Tap "Options" on the top screen to adjust scotoma color and simulate binocular. Tap "Options" again to close the settings screen.
Tap the title of scotoma color or the color picker to adjust the color of tunnel and scotoma effects.
You can switch between still image and video modes using the button at the bottom left corner of the top screen.
When a keyboard is connected, you can control the app using shortcut keys. Press and hold a shortcut key to quickly change the corresponding value.
On iPad, press and hold the ⌘ key to see a list of shortcut keys.

Profiles save the values of effects and the contents of options. By switching profiles, you can bring up different simulations.
To add or edit a profile, tap the profile button at the top and select "Manage…" from the menu.
The values of effects and the contents of options are automatically saved to the currently selected profile. Lock the profile to prevent overwriting.
You can also share the profiles you have created. Tap the "Export" button at the upper right corner of the profile editing screen. To import a profile, tap the "Import" button at the upper right corner of the profile list screen.
