Geometry Dash APK is a visually intense game with bright colors, fast movements, and flashing lights, which can be both stimulating and challenging for your eyes. Prolonged gameplay, especially if you're deeply focused, can lead to eye strain, manifesting as symptoms like dry eyes, headaches, and even blurred vision. The game's high contrast and vivid visuals can be particularly taxing, making it important to take regular breaks to rest your eyes. Adjusting the brightness of your device and playing in a well-lit environment can help minimize these effects. While the game itself isn't inherently harmful, playing responsibly and being mindful of your screen time can help ensure that your eyes remain healthy.
