The short answer is that there is no evidence that keratoconus can worsen through excessive computer use. Read on to learn more about computer use and keratoconus.
Some experts note that excessive computer use may contribute to dryness, which causes some people to rub their eyes. As with all activities that may lead to eye-rubbing, alternatives should be sought to prevent all instances of this common but potentially injurious behavior of eye-rubbing. This includes administering eye drops for severely dry eyes and taking breaks from screen time.
Nevertheless, there are other conditions such as digital eye strain, also known as Computer Vision Syndrome (CVS), which can be caused by excessive time spent in front of computers and other digital screens. CVS is not considered serious and the effects are temporary. By following the appropriate recommendations, the effects dissipate or go away in time. Please refer to the section on Computer Vision Syndrome for more information.
