That looks like the beginning of a clickbait advertisement or viral health-video script.

Claims such as “Japan’s oldest doctor: Eat THIS before bed to improve your eyesight while you sleep” are usually exaggerated. There is no known food that can dramatically improve eyesight overnight while you sleep. Good nutrition can support eye health over time, but it won’t reverse most vision problems. (drmashir.com)

Many versions of this headline online promote different foods (often goji berries or similar “superfoods”), but the evidence generally supports only modest eye-health benefits from nutrients such as vitamin A, lutein, zeaxanthin, vitamin C, vitamin E, and omega-3 fatty acids—not miraculous vision restoration.
