![]() The light should be behind you whenever possible to prevent shining in your eyes. Instead, position task lighting for reading so light is directly illuminating the pages. Usually, the overhead lighting from a lamp is not enough. If you’re reading text materials, think about task lighting. Adjust lighting accordingly and dim the screen to a comfortable level to reduce glare. If you’re reading on an illuminated device, the lighting in the room should always be brighter than the screen to prevent glare-related strain. Reading without adequate lighting also causes eye strain. We have no long-term data about the risk of screen use and childhood eye/vision/brain development, so it’s always best to err on the side of caution. If you let your children play games or watch shows/movies on gadgets, explain the rule and set a timer for their eye breaks, too. Other tips include keeping preservative-free eye drops on hand to refresh the eyes, keeping screens at arm’s length away, and using glare-reducing tools. Set a time on your watch or gadget when working online or using a screen to keep track. In our post, Eye Strain Caused By Too Much Screen Time, we discuss how to minimize or prevent the risk of digital eye strain, including the 20-20-20 rule take a 20-second break to view something 20 feet away every 20 minutes. Also called digital eye strain, the syndrome relates to several conditions linked to too much screen time with insufficient breaks. The American Optometric Association has defined a new range of eye problems, called computer vision syndrome, due to the rising number of eye and vision problems we see in our offices. These days, much of our reading takes place on illuminated screens rather than pages. These appointments are especially important for younger children who may not realize they have vision issues without routine exams. Scheduling routine annual eye exams is the best way to make sure your eyes aren’t working too hard to focus when reading things that are close up (books/magazines/eReaders), medium distance (computer screens), and further distances (television, traffic signs, classroom whiteboards, etc.). Time flies, and your eyes, optic nerve, and brain may be scrambling to compensate for vision changes causing eye strain while reading. The first step in preventing eye strain is ensuring you have glasses if needed, and verifying existing prescriptions for current glasses or contacts are still valid. The following tips can prevent eye strain and any associated side effects.
