A goggle lens coupled with a goggle frame (8) for enclosing a wearer's head includes a central lens portion (1) and two lateral lens portions (2) respectively extending from left and right sides of the central lens portion (1). The central lens portion (1) includes a central convex surface (12) distal to the wearer's face and having a first horizontal radius of curvature. Each lateral lens portion (2) includes a first lateral lens section (21) which has a first convex surface (212) distal to the wearer's face and has a second horizontal radius of curvature. The second horizontal radius of curvature is smaller than the first horizontal radius of curvature such that the central lens portion (1) is closer and more fittingly attached to the wearer's face to improve the aesthetic appearance of the goggle lens.
