Definitions:

Octopus Eyes

Complex visual organs in octopuses that are capable of image formation, color vision, and polarization sensitivity, despite being structurally different from vertebrate eyes.

Blind Spots

Regions in the visual field where no image is detected because no photoreceptors are present, notably where the optic nerve exits the eye.

Camera-Vision

A method of vision similar to how a camera operates, typically referring to the ability of some organisms to focus light onto a receptor surface to form a visual image.

Live-Virus Vaccine

A vaccine that uses a weakened form of the virus to stimulate the immune response without causing the disease.
