How to join through an EOS Branch or Affiliated Society

If you have a national optical society in your country that is a Branch or Affiliated Society of the EOS you may join two societies at once by becoming a member of your national society and thus automatically a member of the EOS as well.
Please check the map of the national optical societies within the EOS to find out if your national optical society is a member of the EOS, or contact us at info@myeos.org.
Annual fee: determined by the EOS Branch or Affiliated Society.
