1. How they work (simple version)
They have a clear “line” (some are subtle) dividing the lens into two parts:
Top part: Lower power (or no power). For seeing far things, like driving, watching movies, or looking at distant signs.
Bottom part: Higher power. For close-up tasks, like reading books, scrolling phones, typing on computers, or doing small crafts.
2. Who needs them?
Mostly people with presbyopia (when your eyes can’t focus on close things as you get older)—especially if you also need glasses for seeing far (like nearsightedness).
Folks who switch between far and close vision a lot: teachers (blackboard + grading papers), doctors (patient charts + tools), or office workers (talking to coworkers + staring at screens).
