Optometry and Contact Lenses (OCL)
Official journal of Vereinigung Deutscher Contactlinsen-Spezialisten und Optometristen (VDCOe.V., Association of German Contact Lens Specialists and Optometrists)
Aims and Scope
Optometry and Contact Lenses (OCL) is a journal published ten times a year, covering all aspects related to eye and vision care. It publishes scientific and clinical articles as well as case reports focusing on ophthalmic optics, optometry, ophthalmology and related disciplines. OCL also contains interviews with public figures in the fields covered by the journal, book reviews of new and current publications in the fields of eye and vision care as well as association information from VDCO. In addition, each issue also contains a section called COE Continuing Optometric Education, featuring a COE certified article with a multiple choice quiz. COE participants can earn two COE credits when they achieve the passing score for the quiz.
Each article is peer-reviewed before publication.
Opticians, optometrists, ophthalmologists and doctors who are in further education to become ophthalmologists as well as students from Germany, Austria and Switzerland studying ophthalmic optics, optometry, ophthalmology and related disciplines.

COE Certified Continuing Education
Continuing Optometric Education (COE) is the umbrella term for certified continuing education courses and programmes in all areas of optometry. One COE point is awarded for successfully completed COE certified courses in Optometry and Contact Lenses (OCL). Each issue of the journal contains a COE certified article with a quiz. This can be a scientific article, a clinical article or a case report. The Editorial Board of the journal selects the article to be published. The quiz is designed as a multiple choice test following the guidelines of the German Quality Association for Optometric Services (GOL).
Structure the article as follows:
- Material und Methods
Do not number sections.
A separate title page should be structured as follows:
- Short and concise title (up to 60 characters)
- All authors‘ full names, academic degrees, institutional affiliations as well as complete postal and email addresses of all authors
- Corresponding author’s name and contact details (for purposes of correspondence with the Editor-in-Chief and reviewers during the peer review process)
Cite references in the text in ascending numerical order inserting superscript Arabic numerals. Use ascending numerical order in the Reference section too. References and journal titles should be listed according to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (http://www.icmje.org). It is recommended to use Citation Style Language (CSL) for references. The required CSL format for "Optometry & Contact Lenses (OCL)” can be downloaded free of charge at ocl-online.de.
