The artificial retina is a medical device that aims to reconstruct the vision of people with severe visual impairment, and the main target disease is retinitis pigmentosa (RP). RP is a disease of the retina and is the second leading cause of blindness in Japan, but there is no effective treatment. The artificial retina acquires an image of the outside world with a small camera, and based on the image data, a stimulation current is created with an electronic circuit. The stimulation current is transmitted to the retina through the multipolar electrode to create a light sensation. In order to make this useful, visual rehabilitation is required and we will do this research.

Also, with the spread of smartphones and HMDs, eye fatigue has become a social issue, and there is concern that myopia in children will also increase. We will evaluate digital devices with less burden on the eye, glasses to reduce the burden, and contact lenses, and conduct joint research to achieve comfortable vision.
