Abstract

We evaluated the effect of astaxanthin on visual function in 49 eyes of 49 healthy volunteers. They were over 40 years of age. They were divided into 4 groups matched for age and gender. Each group was given peroral astaxanthin once a day. The dosage was 0 mg, 2 mg, 4 mg, or 12 mg for each group. After ingestion of astaxanthin for consecutive 28 days, the uncorrected far visual acuity significantly improved in groups receiving 4 mg or 12 mg. The accommodation time significantly shortened in groups receiving 4 mg or 12 mg. There was no change in refraction, flicker fusion frequency, or pupillary reflex.
