It is understood that this lens can be achieved at the same time control the image clarity and blurring the main three features are: focus, astigmatism, image displacement.
The team said that it can also combine artificial muscle technology to create adjustable lenses, which can be similar to the human eye zoom. Conventional artificial eyes have functions that the human eye does not have, but they can correct nearsightedness, delirium, and the like.
If this lens is placed in the glasses, it can provide great help to the visually impaired. In addition, the technology can also be applied to smartphones' cameras, VR/AR hardware and other products. Changing the focus of glasses in real time is a very promising technology.
Even the technology can be applied to optical microscopes. The Harvard University Technology Development Office has applied for and protected the technology and is currently exploring commercialization opportunities.
