The Indus Valley script remains undeciphered and there are very little surviving fragments of its writing, thus any inference about scientific discoveries in that region must be made based only on archaeological digs. The following dates are approximations. The Nippur cubit-rod, c. 2650 BCE, in the Archeological Museum of Istanbul, Turkey

As of 2009, the European CE mark indicates that the glasses actually offer a certain level of sun protection. Australia [ citation needed ] They were updated and expanded in 1990 to AS 1067.1-1990 Sunglasses and fashion spectacles (incl. Part 1 Safety Requirements and Part 2 Performance Requirements), and replaced in 2003 by AS/NZS 1067:2003 ...
