Inclusion criteria
Inclusion criteria: P: Participant The subjects were healthy adults (those who are not suffering from any diseases, excluding those under 18 years old, pregnant women, and lactating women). I: Intervention(food) characteristics The intake of ingredients was equivalent to the anthocyanins derived from bilberry used in the final product. There were no restrictions on intake amount, intake period, or follow-up period. C: Comparison group Comparisons were made with a placebo group or a control group in which the test food was replaced with a food that did not contain bilberry-derived anthocyanins. O: Evaluation items Main outcomes: Relieves eye fatigue by improving the eye's accommodative function (near point distance, accommodative power, and accommodative time). Secondary outcomes: Effect in relieving eye fatigue based on subjective evaluations (VAS, subjective symptom questionnaires, etc.). S: Research design The research designs used in the included literature were randomized parallel-group controlled trials (RCTPs), randomized crossover trials (RCTCOs), and quasi-randomized controlled trials (quasi-RCTs).The included studies were written in Japanese or English. In principle, the presentation format was an original paper; however, short reports or summaries were also accepted if the content was clearly specified.Abstracts from academic conference presentations (conference proceedings) were excluded due to insufficient descriptive content. Whether or not the journal was peer-reviewed was not used as an exclusion criterion.To minimize publication bias, studies with results published in clinical trial registry databases were also included.Regarding gray literature, doctoral theses and reports from government agencies or think tanks were included if their detailed content could be identified.
