Question

read the text. university of utah engineers have developed \smart glasses\ designed to act like the eyes natural lens. some people struggle to focus on things close up, far away, and in between. as a result, they may wear different glasses to see at different distances. the smart glasses have liquid - based lenses that respond by flexing and bending to focus on whatever the wearer is looking at. the trouble is people move their eyes very quickly as they look at different things. the glasses address this by adjusting even faster than the eyes natural lens refocuses. the glasses change shape to refocus in fourteen milliseconds! normally, glasses wearers would have to buy a new pair as their eyesight changes over time. since smart glasses automatically adjust to wearers eyesight, people would only need one pair. match the problems with their solutions. the glasses can focus in fourteen milliseconds. the lenses can flex and bend. one pair of glasses can adjust automatically. problem: people have to focus at multiple distances. people move their eyes continually. peoples eyesight changes. solution:

Explanation:

1. For the problem "People have to focus at multiple distances", the solution is that "The lenses can flex and bend" as these lenses can respond to focus on whatever the wearer is looking at.
2. For the problem "People move their eyes continually", the solution is that "The glasses can focus in fourteen milliseconds" since they adjust even faster than the eye's natural lens refocuses to keep up with quick - eye movements.
3. For the problem "People’s eyesight changes", the solution is that "One pair of glasses can adjust automatically" as smart glasses automatically adjust to wearers' eyesight.

Answer:

People have to focus at multiple distances - The lenses can flex and bend.
People move their eyes continually - The glasses can focus in fourteen milliseconds.
People’s eyesight changes - One pair of glasses can adjust automatically.
