If you’re spending many hours editing content, browsing resources, or working through threads, your eyes are doing more than you think and can easily become strained from glare, brightness contrast, and constant focus at the same distance. Beyond ergonomic setups and regular breaks, it’s also useful to check whether your screen itself might be contributing to fatigue or visual distortion. A quick way to spot glare, uneven brightness, or subtle surface issues is to use an online black screen tool — it fills the display with a plain dark background that makes irregularities stand out much more clearly than busy content does. Taking a minute to do this simple check not only helps you notice display quirks but also gives your eyes a calming visual reset before you dive back into work.
