Optics.
The study of light and vision is known as optics. It involves understanding how light interacts with different materials and how the human eye processes visual information. Optics is important in various fields such as physics, astronomy, and ophthalmology.

That branch of physical science which treats of the nature and properties of light, the laws of its modification by opaque and transparent bodies, and the phenomena of vision.
No Light Perception (NLP vision)
The study of light, or optics, reveals how light behaves and interacts with matter. This knowledge has numerous applications, from understanding vision to improving technologies like microscopes, telescopes, lasers, and fiber optics. Additionally, studying light helps us gain insights into fundamental aspects of physics and the nature of the universe.
Jellyfish do not have any vision. They have light sensitive organs, which informs them where light is, but cannot see.
The retina of the eye requires light in order to work. Vision is stimulated when light strikes this layer of the eye, so if there is no light, there is no vision.
Seeing light in your peripheral vision can be caused by the way your eyes are designed. The cells in your retina that detect light are more sensitive at the edges, so you may notice light more easily in your peripheral vision.
Physicists study light.
No. Night Vision equipment uses infra-red (IR) light, wavelengths of light longer (lower frequency) than visible light. Infra="below", red, or light below red light in the spectrum. UV stands for ultra (above)-violet, light that is above the violet light spectrum, so higher frequency=shorter wavelength.
No, night vision goggles do not emit light. They work by amplifying existing light, such as moonlight or infrared light, to enhance visibility in low-light conditions.
The light receptors in the eye are called cones and rods. Cones are responsible for color vision and detailed vision in bright light, while rods are more sensitive to low light levels and are important for night vision.
