Myopia, commonly known as nearsightedness, is a refractive error that causes distant objects to appear blurry. It is a condition that affects approximately one-third of the global population, and its prevalence is expanding: global trends predict nearly 50% of the world’s population will be myopic by 2050.

It happens to the best of us at some point in our lives; you could be sitting in a movie theater, driving to work, or just relaxing on the couch, when all of the sudden your eyelid starts to twitch. Eyelid twitching (or myokymia) is an involuntary eyelid muscle contraction, which typically affects your lower eyelid, not your actual eyeball. An eye twitch (albeit annoying) is usually nothing serious. These spasms are pretty common and may come and go, without an identifiable trigger.
