  • Publication number: 20230048358
    Abstract: The present invention provides an edible composition for alleviating visual fatigue. The composition comprises in parts by weight 1 to 10 parts of curcuma powder, 1 to 12 parts of whole coffee fruit extract, 1 to 20 parts of phospholipid composite, 1 to 15 parts of DHA, 0.5 to 5 parts of phosphatidylserine, and 0.1 to 5 parts of vitamin C. After one week of trial consumption by the subject, the duration of photopic vision is improved with a significant difference in comparison with that before the trial; after 2 weeks of trial consumption, the overall score of visual fatigue symptoms decreases with a significant difference in comparison with that before the trial; after 8 weeks of trial consumption by the subject, the vision field thereof is remarkably enlarged, indicating the formulation may prevent the occurrence of glaucoma. The coffee extract combined with the remaining ingredients has a synergistic effect.
