ACTIVE NOT RECRUITING

NCT07135180

Exploring the Eye Care Benefits of Cordyceps Cicadae Across Different Age Groups

The aim of this study is to evaluate the underlying mechanisms of consuming two capsules (each containing 250 mg of Cordyceps cicadae mycelium, for a total intake of 500 mg) of Grape King's Cordyceps cicadae mycelium through a clinical human trial. By including participants from different age groups, the study investigates whether improvements in visual acuity and the alleviation of eye fatigue are associated with changes in ocular accommodation, tear film stability, and blood circulation. The ultimate goal is to develop a health supplement beneficial for vision.

The Changes Under Different Accommodation of Anterior Eye and 3D Crystal Reconstruction.

Accommodation is defined as a dynamic change in the overall refractive power of the eye during near fixation. Despite extensive investigations, the exact nature of human accommodation remains controversial. And recent alternative theories question the original concept of accommodation.Different experts have put forward different hypotheses. The age-related changes that underlie presbyopia are also not fully understood.Because of these unanswered questions, the topic of regulation and presbyopia remains a focus of research.
