Optical creates an optical illusion that makes you feel like whatever you are looking at is both shrinking and growing at the same time. You have to witness this effect to believe it.
Optical displays a special pattern of converging, diagonal lines. Focus on the center of the pattern and stare for about 30 seconds. When you look up, your vision will be warped for a few seconds. Focus on any object in the room and prepare to have your mind blown.
Photosensitive Seizure Warning
A very small percentage of people may experience a seizure when exposed to certain visual images, including flashing lights or patterns that may appear in applications such as Optical. Even people who have no history of seizures or epilepsy may have an undiagnosed condition that can cause these "photosensitive epileptic seizures" while watching these images.
These seizures may have a variety of symptoms, including lightheartedness, altered vision, eye or face twitching, jerking or shaking of arms or legs, disorientation, confusion, or momentary loss of awareness. Seizures may also cause loss of consciousness or convulsions that can lead to injury from falling down or striking nearby objects.
Immediately discontinue use and consult a doctor if you experience any of these symptoms. Parents should watch for or ask their children about the above symptoms. Children and teenagers are more likely than adults to experience these seizures.
The risk of photosensitive epileptic seizures may be reduced by taking the following precautions:
•Use in a well-lit room
•Do not use when you are drowsy or fatigued
If you or any of your relatives have a history of seizures or epilepsy, consult a doctor before use.
Do not use this application in the presence of animals.
Do not use this application in the presence of anyone who has not read this warning or does not understand the above information.
