Specially coated lenses that reflect the color spectrum of blood and thus represent it as black.
Blood is disturbing to most people and can lead to severe trauma and mental illness.
The coated lenses of the blood filter glasses refract the special red tone from the blood differently from the rest of the colors.
Thus, the wearer of the blood filter glasses sees everything that is blood red as black or gray. So it is less disturbing for the wearer.
The RUBI glasses developed are specially coated versions that specifically reflect the color spectrum of blood and display it in the color black.
It is usually too late when a person realizes that it is doing more to them than they may have previously admitted and terrible images are burned into their minds. Terrible images of the accident can accompany even the strongest men and women for years.
Blood red is a color that can trigger a lot in the brain. This has been the case since time immemorial and is anchored in the collective memory. The blood filter glasses were developed to reflect light above a certain wavelength and thus filter the color blood red from the color spectrum.
Never see red again! Blood puts a strain on the psyche and can result in trauma.
