Floater Simulation lets you use your device to show the world your experience with eye floaters. Open the app and tweak the settings to best show your close ones what your every day suffering is like. You can also record a short clip to share on Facebook and the like. Eye floaters are small moving spots that appear in your field of vision. They may be especially noticeable when you look at something bright, such as white paper or a blue sky. Floaters are deposits of various size, shape, consistency, refractive index, and motility within the eye's vitreous humour, which is normally transparent. At a young age, the vitreous is transparent, but as one ages, imperfections gradually develop. The common type of floater, which is present in most persons' eyes, is due to degenerative changes of the vitreous humour.
