Train your brain, help your vision and have fun. We help your brain. With Virtual Reality we have created activities to teach your brain to work with both eyes that have been designed under the supervision of ophthalmologists. Fun exercises The exercises in DICOPT look like mini-games to test your binocular vision. In addition, the games are available in 2D for cell phones, with which you can have fun, as they do not serve as therapy in these modes. Research in the treatment of lazy eye We stimulate each eye independently, so that certain elements of the games are shown in one eye and other elements in another, known as dichoptic exercises. This technique is used for the recovery of lazy eye. First version of the app, which includes 4 games in its non-therapeutic mobile version for free. If you want more information about the games to treat lazy eye and to be aware of everything, visit https://vvision.eu
