How to use

Select one illusion then get ready and keep your mobile device (phone or tablet) about 25 cm in front of your eyes.Once the spiral visual effect starts its movement a counter shall show on the center of the screen the time remaining you should keep looking at the screen of your mobile device. 30 seconds is an amount of time which we have tested and works fine on the majority of devices we have used during the test time. During those 30 seconds you can focus on different ways on the screen, any way you focus your eyes on it shall be fine to achieve the goal expected after the counter reaches zero. Once the time is over, then look at some object around you in a middle distance, then you should be able of seeing the optical illusion effects. In case you haven’t achieved seeing the effects, you can answer how was the result of your try in the game, and extra tips shall be given in such a case.

Optical Illusions (also called Visual Illusions) can use color, light and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is processed by the brain, creating a perception that in reality, does not match the true image. Perception refers to the interpretation of what we take in through our eyes. Optical illusions occur because our brain is trying to interpret what we see and make sense of the world around us. Optical illusions simply trick our brains into seeing things which may or may not be real.

We hope you enjoy the app. Keep in mind our disclaimer about stroboscopic images sensitiveness.
