Changing the clocks for daylight saving time may do more than make people feel tired. Previous studies have already linked daylight saving time, especially the spring clock change, with a higher risk of heart attacks and strokes. The study does not prove that daylight saving time directly causes eye disease. Even so, the findings suggest doctors may want to pay closer attention to people who develop new vision symptoms after the spring clock change. If you care about eye health, please read studies about how vitamin B may help fight vision loss, and MIND diet may reduce risk of vision loss disease.
