The Limits of Human Vision

 Look into my eye....

I saw this interesting article about the sense which I find most important, being a visual artist:

BBC Future:

What Are the Limits of Human Vision?

Originally a congregation of cells that evolved to react to electromagnetic radiation, the organ we call the eye is one of the countless marvels of biology.

Despite the power of sight, our eyes only pick up a small slice of the energetic reality surrounding us. We adapted to see only what we need to to survive in our particular circumstances.

Life in Thermal Vision

As technology advances and digital interfaces are developed to enhance our senses, it's possible that one day humans will be able to detect other energy wavelengths or have a wider range of vision.

I always wondered what the "resolution" of human eyesight is compared to the pixel dimensions of computer screens. It turns out we see at about 120 pixels per degree of arc, which ends up being around 500-600 megapixels.

The eye and visual perception are sources of constant wonder for me. The ability of the eye and the brain to process light energy into recognizable form is a marvel, but it is also fundamental to how humans and other lifeforms perceive our world.
