Many companies are making special contact lenses. One company in America is making contact lenses with augmented reality functions. These lenses will have small displays. They will be the size of a grain of sand. Through the display, you can see information about the world around you. Another company wants to make lenses with zoom functions. That way, you can zoom in on what you are seeing! Another company wants to make lenses with night vision. This might be useful for the military. Science is really changing our lives!
