Fluid-Filled Lens Mimics Best Traits of Human Vision
Take a look at your eyes (shhh, just do it). They are among the most incredible visual systems on the planet. Your eyes can manage light in an immense variety of situations, and can focus on objects from infinity to near macro levels (when you were younger). Mechanical lens systems have tried to replicate what nature does so easily only to fall short thus far.
Ohio State University has broken new ground however, and developed a fluid filled lens that can change shape like our eyes do.
The lens is a flexible polymer and designed similar to an insect’s via multiple miniature lenses nested inside. Each is capable of being individually adjusted to achieve it’s desired focus. When it comes to application it seems unlikely that a liquid filled item would make it into many electronics but anything is possible.
