Australia is one of the few countries still defying international sunglasses standards that would, if enacted, actually lower the sunnie standards in Australia. Australia has labels on deep red, yellow and brown tinted sunglasses that warn consumers of the danger of driving in these tinted sunglasses. Under current standards, blue-light blocking sunglasses are labeled unsuitable for driving if they block over 30% of blue light, because they block much of the blue-green light emitted from traffic lights.
Because a sizable percentage of the population suffers some sort of color blindness or color dulling (over 8% in men and 1 in 200 for women) the traffic lights have been imbibed with a subtle blue tint, which is easier for color blind or deficient people to see than green. The dark red, brown and yellow sunglasses that block over 30% of blue light are dangerous in driving situations and are thus properly labeled. In a study performed recently many color blind/deficient test subjects wearing the European standard 60% blue block sunglasses could not distinguish light colors varying from yellow, green, blue and in some cases red. The dangers pointed out by this study are obvious for color deficient citizens wearing the international standard sunglasses while driving.
If Australia were to adopt international safety standards it would mean dropping the warning labels off of the potentially dangerous eyewear. Many Australians are unhappy with the European pressure to change the warning from all 30% blue blockaded eyewear to a drastic 60% blue-block. While the economic crisis worsens, some Australians see the pressure to change warning labels as a sign that manufacturers in Europe see the labels as hampering sales in Australia.
