The built-in 3D fit pad is removable, so you can use it with the pad for enhanced light blocking, or without the pad for a lighter, more relaxing feel, depending on your preference and mood. The 3D fit pad creates a space around the eyes, designed not to directly press on the eyeballs, reducing strain on the eyes even with prolonged use. Additionally, its soft multi-layer structure provides a snug fit, making it less likely to leave marks.
