'Bug-eyed' lens takes a broader view

The eyes of insects such as bees and dragonflies are made up of tens of thousands of tiny components called ommatidia. These all point in different directions to give the insect a very wide field of vision.

Inspired by this, Luke Lee and colleagues developed an artificial compound eye consisting of a moulded polymer resin dome filled with thousands of light-guiding channels, called waveguides, each topped with its own miniature lens.

The artificial eye could be used to create surveillance cameras, cellphone cameras, and surgical endoscopes with a much wider field of vision, the researchers say.

I wonder of the "Grays" make use of something similar to this. Once you concede that

a.) they physically exist

and

b.) might be manufactured beings

you have to wonder. Researchers have noted that the eyeballs typically depicted in pictures of Gray aliens are too big to fit inside the skull without crowding out the brain. This suggests we're dealing with exaggerative caricatures. But it could also mean the ubiquitous slanted black "eyes" are prosthetic devices.
