Myopia, or nearsightedness, is a global problem. The World Health Organization is sounding the alarm. In Japan, more and more reports show that myopia is increasingly serious among children, and that it continues to worsen when the children grow up. The latest research shows that myopia increases the risk of eye disorders such as cataracts and glaucoma. It also reveals a correlation with depression, dementia and other conditions that have no obvious connection with the eyes. This documentary investigates what is happening to our eyes, and how we should change our lifestyles to protect them.
