Avoiding eye strain while working at the computer is essential for maintaining eye health and comfort. To prevent discomfort and fatigue, ensure proper lighting in your workspace, with ambient and task lighting to reduce screen glare. Follow the 20-20-20 rule: every 20 minutes, look at an object 20 feet away for 20 seconds to give your eyes a break. Adjust your monitor's settings for optimal brightness, contrast, and font size. Position your screen at eye level and maintain a comfortable viewing distance to reduce strain. Blink frequently to keep your eyes moist, and consider using artificial tears if needed. Finally, schedule regular eye exams to address any potential issues and ensure your eyes stay healthy during extended computer use.
