A person using a retinal implant to see will not experience vision in the same way a person with healthy eyes does. It will be quite basic to start with and they will need training to adapt to the implant. With time, training and patience, people will be able to use this visual information to be more independent and mobile. 

The retinal implant bionic eye works by stimulating the perception of light in a patient. A phosphene is a perceived spot of light in the visual field. What our technology aims to do is stimulate many of these phosphenes across the visual field in a way that enables the patient to put together a picture of what they are looking at.

The more electrodes an implant contains, the more phosphenes are capable of being generated and the more detail a patient may be able to see. The first wide-view prototype device has 98 electrodes. The second High-Acuity device has more than 1024 electrodes.
