Introducing The World’s Only Colour-Blind Safety Glasses
As someone who is colour-blind or “a decreased ability to see differences in colour” [I am a Protan (Protans are people with protanomaly, a type of red-green colour blindness in which the red cones do not detect enough red and are too sensitive to greens, yellows, and oranges. As a result, greens, yellows, oranges, reds, and browns – Just as well I’m a Manchester City supporter then!], I am intrigued by the colour-blind glasses by Enchroma and others. If they were available in opticians in Thailand then I would definitively be interested in trying them out to see if they can be of help to me or not.
What does this have to do with construction and engineering I guess you are thinking, well it turns out that Enchroma produce ‘The World’s Only Colour-Blind SAFETY Glasses’ – “on the job” colour vision and eye protection with our full line of trend-forward protective eyewear for color blindness. All EnChroma safety frames and lenses meet ANSI Z87.1 recommended impact standards to help reduce the risk of impact-related injury and protect from UV radiation, dust, dirt, and splashes.”
Worth considering if you are colour-blind, work on construction and engineering project sites and have to wear protective eyewear.
If you want to check out if you are colour-blind, and if you are, which type of colour-blindness you have, then have a go at this colour-blind test.
Interesting facts about colour-blindness from Wiki:
The most common cause of color blindness is an inherited problem in the development of one or more of the three sets of the eyes’ cone cells, which sense color.
Among humans, males are more likely to be color blind than females, because the genes responsible for the most common forms of color blindness are on the X chromosome. Females have two X chromosomes, so a defect in one is typically compensated for by the other.
Non-color-blind females can carry genes for color blindness and pass them on to their children.
Males only have one X chromosome and therefore always express the genetic disorder if they have the recessive gene.
Color blindness can also result from physical or chemical damage to the eye, the optic nerve, or parts of the brain.
Diagnosis is typically with the Ishihara color test; other methods include genetic testing.
There is no cure for color blindness.
Red–green color blindness is the most common form, followed by blue–yellow color blindness and total color blindness.
Red–green color blindness affects up to 8% of males and 0.5% of females of Northern European descent.
The ability to see color also decreases in old age.
In certain countries, color blindness may make people ineligible for certain jobs, such as those of aircraft pilots, train drivers, crane operators, and people in the armed forces.
The effect of color blindness on artistic ability is controversial. The ability to draw appears to be unchanged, and a number of famous artists are believed to have been color blind.
The first scientific paper on the subject of color blindness, ‘Extraordinary facts relating to the vision of colours’, was published by the English chemist John Dalton in 1798 after the realization of his own color blindness. Because of Dalton’s work, the general condition has been called daltonism, although it usually refers specifically to red–green color blindness.
Some countries have refused to grant driving licences to individuals with color blindness. The usual justification for such restrictions is that drivers of motor vehicles must be able to recognize color-coded signals, such as traffic lights or warning lights. Thailand is among the countries which includes a colour-blindness test to get a driving licence, UK and Australia are NOT among the countries which includes a colour-blindness test to get a driving licence.
