I have tried to keep this short so I do not loose anyone, as I know most of this might be boring. But, I hope that it will intrigue a few.
The human eye is a type of light detector and the optic nerve is the method of sending information and
images to the brain. It runs from the back of the eyeball and through the optic fora-men, where it connects with the brain. This nerve transmits the signals for vision to the brain making vision possible. Our light detectors pick up white visible light, which in short contains all the colors of the rainbow from red to violet. While the human eye can see red, it can not see infrared. However, there are some who do not have a lens, which is located directly behind the iris and is used to focus light into the retina allowing them to see infrared.
The approximate range of wave length of EM radiation from 380nm to 760nm.
This is why many paranormal investigators us IR only camera's.
(Infrared is also called IR).

380nm to 450nm - 688 to 789 THz - Violet
450nm to 495 nm - 606 to 668 THz - Blue
495nm to 570nm - 526 to 606 THz - Green
570nm to 590nm - 508 to 526 THz - Yellow
590nm to 620nm - 484 to 508 THz - Orange
620nm to 750nm - 400 to 484 THz - Red
665nm to 900nm - 120 to 400 THz - Near Infrared
“Researchers at the University of Pennsylvania School of Medicine estimate that the transference of information from the eyes to the brain runs at about the speed of an Ethernet connection (Kreeger, 2006)”
I bring up a short version on this topic, because of the connection of the human eye, electromagnetic spectrum, rhythm waves (alpha, bata, delta, & theta) also work on frequencies, are all transmitted according to the person differently to the brain. Some of us who have the ability to see ghost and non-physical beings do so because we are more sensitive to the electromagnetic filed that all things have.
More energetic waves have shorter wavelengths while less energetic waves have longer wavelengths. Like IR Light electromagnetic radiation, the wavelength's that are too long can not be seen by the naked human eye to detector.
(SEE MY CHART ABOVE)
Full- Spectrum -
Covers the electromagnetic spectrum from infrared through and to the edge of Ultra vilote. Such as the sun is considered full spectrum.
Ultraviolet Light -
electromagnetic radiation with shorter than visible light. However it is longer than that of X-Ray in the range of 10nm to 400nm. Most importantly the energies from 3e V to 124 e V.
UV is also classified as non-ionizing radiation and the higher the energies of the UV spectrum for example: 150 nm are ionizing (vacuum UV).
Low Energy Light-
LED Light – is also known as light emitting diode (EL-ee-DEE), what is it? It's a semiconductor source. You may be more familiar with them in flash lights and now, even as the new light bulbs for inside homes. The LED's have a very bright source and have a broad spectrum from visible, ultraviolet and infrared.
