Starting around age 40, everybody with good distance vision needs reading glasses. One of the solutions that has been used are “pinholes” that can be implanted in the cornea (as “inlays”), which can help focus light so that reading is easier without reading glasses. Pinholes in general serve the function of focusing light, so even people with bad distance vision can help their vision by looking through pinholes.
I recall inlays being a very popular idea at one time, but I haven’t heard much about that lately. It is my personal opinion that these “pinhole” inlays are not really going to be the solution to the reading glasses problem, so I expect that I will continue to hear less and less about them, at least until there is a major improvement in the technology.
