A total of 4124 people who had undergone cataract surgery in the west of Australia were included in this study.

According to the serum 25 hydroxyvitamin D concentration, the subjects were divided into high concentration group, medium concentration group and low concentration group. Finally, the relationship between vitamin D concentration and myopia was evaluated.

Results: the concentration of vitamin D had little effect on adult myopia!

One explanation is that serum 25 hydroxyvitamin D deficiency does lead to myopia, but the effect is mainly between 5 and 25 years old (during the occurrence and progression of myopia). Some people with myopia in adulthood have changed their work and rest, exposure to sunlight has become longer, serum 25 hydroxyvitamin D concentration has been increased, but it can not change the myopia that has occurred.
