A refereed journal has a formal peer review process where articles are reviewed by several other experts in the field (“peers”) before they are published in the journal. A refereed journal is also called a peer-reviewed journal. You can find this information on the journal’s website. For example, the Canadian Journal of Ophthalmology (CJO) would qualify as a refereed journal as it publishes original, peer-reviewed ophthalmology and vision science articles.
