Screens, books, driving, and poor light are all well-known sources of eye strain—but what’s less well known is that the onset of discomfort can take a while to begin, meaning that you may only feel straining the morning after a late-night Netflix binge.
Aching, twitching, and even sharp pains can be caused by overuse of technology, which The American Optometric Association calls Computer Vision Syndrome or Digital Eyestrain. Interestingly, the same symptoms sometimes occur after spending the previous day in the sun, without sunglasses.
If you’re experiencing these symptoms, but don’t feel you’re taking part in eye-straining activities, you might have a condition called Nocturnal Lagophthalmos. As described by Healthline, Lagophthalmos is the medical term for the inability to fully close the eyelids when sleeping due to nerve or bone damage.
If you normally wear glasses or contact lenses, consider whether it’s time for an eye test. Using the wrong prescription throughout the day can leave your eyes strained and aching during the night and into the morning. This may also be accompanied by headaches and feelings of dizziness.
