Hyperopia, or a difficulty in focusing on near objects, is common among many individuals, especially in middle aged and elderly demographics. This is manifested in the fact that many individuals over the age of 40 prefer to read with reading glasses.
However now that much reading is done on an electronic display, reading glasses may become a thing of the past. A team of researchers at UC Berkeley, MIT, and Microsoft have come up with an exciting alternative solution. They are working on electronic screens that can alter their display based on a user's glasses prescription. When a prescription setting is enacted the screen may look blurry to someone with perfect vision, but to someone with hyperopia the screen would be in focus and would appear exactly the same as it would if viewed through glasses!
No more lost reading glasses!
