This app is to simulate sight of dog and cat, sight of human who has disease of eyes, by filtering camera image. The filtered camera image can be saved to photo library as a still image.

The simulated sights are as follows;

- Normal Color Vision (no filtered)
- Color vision of dog
- Color vision of cat
- Color vision of Cataract
- Color Vision Defect
- Vision of Age-related Macular Degeneration (Wavy vision, Blurry or Fuzzy vision, Loss of vision)
- Vision of Glaucoma (Loss of vision)
- Vision of Floaters

The image filters to simulate these visions are developed by referring to open to public and generally recognized information related to visions described on the internet or other sources. Therefore, this simulation does not guarantee their actual visions.

It is preferable for those who keep dogs and/or cats, those who have a family or neigberhood with disease of eyes to use this app as one of references.
