As people age, their eyesight almost always gets worse. According to the Vision Council of America, approximately 75 percent of adults use some sort of vision correction. But for a patient, buying new glasses every time their vision gets a little blurrier is costly. At the same time, keeping glasses with a prescription that isn’t quite right can cause headaches and other forms of mild discomfort. To fix this, two physicists are developing a pair of smart, vision-corrective eyeglasses. The glasses use a lens, thinner than a human hair, that has a wide range of tunable focal lengths. The user can adjust these focal lengths electronically. A single pair of glasses can thus accommodate a range of eye powers.
