Autofocusing reading glasses of the future
Summary
The condition of presbyopia is to lose our ability to refocus our eyes because of getting older. It’s that near objects come into focus, but far objects necessarily go out of focus. We have to constantly switch back and forth between wearing and not reading glasses. However, Benjamin Franklin invented “ double spectacles”, it’s called bifocals. It had the line, though, it’s ridden and the focal power can vary from top to bottom smoothly. 1) There is another solution to use contact lenses or take LASIK surgeries. 2) It works, though, it means that two eyes see slightly different things. And then, the speaker suggests Autofocusing reading glasses that he studies. It can estimate focusing distance automatically. It means that you don’t have to think about it. 3) However, it’s bulky. It looks heavy objects yet, but soon, it must be improving.
