In middle 2021 were published by Clarivate (formerly known as Institute for Science Information –ISI) the Journal Impact Factor (JIF) and the Journal Citation Index (JCI) in Emerging Sources Citation Index (ESCI). In a previous Editorial we discussed some of the different metrics to measure the impact of scientific publication.1 This was further expanded in the recent International Congress of Optometry and Ophthalmic Optics held by the Spanish General Council of Optometrists in Madrid during May 2021.2

In those previous publications we could testify the solid increase of impact for contents published in the Journal of Optometry, and now we can confirm this with the Journal ranking second in the Emerging Sources Citation Index (table 1). It is also interesting to observe that majority of the journals indexed deliver their contents in a 100% Open Access strategy. Looking back 14 years, Journal of Optometry was among the only scientific journals in the field of Visual Science adhering to such publishing scheme.

To the previous indexing database where Journal of Optometry was earlier included (see previous editorial for a review of milestones)3 now we add the ESCI indexation in an outstanding position. As stated in ESCI Clarivate's webpage, Emerging Sources Citation Index, as part of the Web of Science Core Collection™, “contains quality publications, selected by our expert in-house editors for editorial rigor and best practice at a journal level”.4 This is another step to reinforce the scientific contribution of Optometry to advances in vision science and to the facilitation of access to such information in a strategy to push further the frontiers of knowledge and the quality of life of millions of people benefiting from prevention, early detection, evidence-based treatment and closer follow-up of visual conditions world-wide.

As editors we want to show our gratitude to the hundreds of corresponding authors and thousands of co-authors and reviewers for helping us to bring the Journal of Optometry to this point, another stimulus to continue improving the impact of this Open Access scientific source sponsored by the Spanish General Council of Colleges of Optometrists.
