=== Australia ===
Australia introduced the world's first national standards for sunglasses in 1971.{{citation needed|date=April 2017}} 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 Sunglasses and fashion spectacles.  This aligned the Australian standard to the European standard{{citation needed|date=April 2017}} opening the European market to Australian-made sunglasses.<ref name="Standards Australia">[http://www.standards.org.au/cat.asp?catid=43&contentid=296&News=1 ''no author'' (2002).

Retrieved 21 September 2009.</ref>{{full citation needed|date=April 2017}}  The Australian Standard AS-NZS 1067 defines standards for sunglasses with respect both to UVA (wavelengths between 315&nbsp;nm and 400&nbsp;nm) and UVB transmittance.<ref>[https://law.resource.org/pub/nz/ibr/as-nzs.1067.2003.pdf AS-NZS 1067 (2003) (English)] {{webarchive|url=https://web.archive.org/web/20130813084752/https://law.resource.org/pub/nz/ibr/as-nzs.1067.2003.pdf |date=2013-08-13 }} : Sunglasses and fashion spectacles (By Authority of Australian Consumer Protection Notices No.13 of 2003 and No. 4 of 2005), retrieved 6 April 2017</ref> The five ratings for transmittance (filter) under this standard are based on the amount of absorbed light, 0 to 4, with "0" providing some protection from UV radiation and sunglare, and "4" indicating a high level of protection, but not to be worn when driving.

=== Europe ===
The European standard EN 1836:2005 has four transmittance ratings: "0" for insufficient UV protection, "2" for sufficient UHV protection,{{clarify|is the term really 'sufficient'? what's the relation to the categories mentioned in the list? |date=December 2024}} "6" for good UHV protection and "7" for "full" UHVV protection, meaning that no more than 5% of the 380&nbsp;nm rays are transmitted. Products which fulfill the standard receive a [[CE mark]]. There is no European rating for transmittance protection for radiation of up to 400&nbsp;nm ("UV400"), as required in other countries (incl. the United States) and recommended by experts.<ref name="Huenig"/>  The current European standard, EN 1836:2005, was preceded by the older standards EN 166:1995 (Personal eye protection – Specifications), EN167: 1995 (Personal eye protection – Optical test methods), and EN168: 1995 (Personal eye protection – Non-optical test methods), which in 2002 were republished as a revised standard under the name of EN 1836:1997 (which included two amendments). In addition to filtering, the standard also lists requirements for minimum robustness, labeling, materials (non-toxic for skin contact and not combustible) and lack of protrusions (to avoid harm when wearing them).<ref name="esa">[http://www.esa-sunglasses.com/downloadarchiv/ARTICLE_ON_PPE_STANDARDS_SUNGLASSES_ETC_2-april26.04.doc ''no author'' (2004<!--according to end of document, which explains something "as of 2004"-->).

* Category 0 – 80–100% transmission – for fashion, indoor use, or cloudy days
* Category 1 – 43–80% transmission – low sun exposure
* Category 2 – 18–43% transmission – medium sun exposure
* Category 3 – 8–18% transmission – strong brightness, light reflected of water or snow
* Category 4 – 3–8% transmission – intense sunshine for high mountains, glaciers; not for use when driving or on the road.

=== United States ===
Sunglasses sold in the United States are regulated by the [[Food and Drug Administration]] and are required to conform to safety standards. The U.S. standard is [[American National Standards Institute|ANSI]] Z80.3-2001,<ref>[http://www.freestd.us/soft/110020.htm Freestd, Free Standards Worldwide] {{webarchive|url=https://web.archive.org/web/20170407054016/http://www.freestd.us/soft/110020.htm |date=2017-04-07 }} ANSI Z80.3-2001 "ophthalmics nonprescription sunglasses and fashion eyewear requirements", retrieved 6 April 2017</ref> which includes three transmittance categories. According to this standard, the lens should have a UVB (280 to 315&nbsp;nm) transmittance of no more than one per cent and a UVA (315 to 380&nbsp;nm) transmittance of no more than 0.3 times the visual light transmittance. The ANSI Z87.1-2003 standard includes requirements for basic impact and high impact protection. In the basic impact test, a 1 in (2.54&nbsp;cm) steel ball is dropped on the lens from a height of 50 in (127&nbsp;cm). In the high velocity test, a 1/4 in (6.35&nbsp;mm) steel ball is shot at the lens at 150&nbsp;ft/s (45.72&nbsp;m/s). To pass both tests, no part of the lens may touch the eye.<ref name="autogenerated1">[http://www.mbos.com.my/website/ansi.html ''MB Optics Safety'' (2006).
