Are you tired of squinting at your laptop screen during late-night work sessions or feeling like your eyes are being attacked by an intense brightness? You’re not alone! Many laptop users struggle with finding the perfect balance of screen brightness, especially in low-light environments. In this article, we’ll delve into the world of laptop brightness and provide you with a step-by-step guide on how to lower the brightness on your laptop.
Why Lowering Laptop Brightness Matters
Before we dive into the nitty-gritty of adjusting your laptop’s brightness, let’s explore why it’s essential to do so. Prolonged exposure to high screen brightness can have negative effects on your health and productivity. Here are a few compelling reasons to dim the lights:
