A soft intraocular lens is provided, with IRHD hardness thereof being 40 to 60, wherein distance L is in a range of 3.75mm - 4.50mm, which is a distance from an optical central axis of the optical part to a reference point of a supporting part side edge of the transition part, and an angle ¸ is in a range of 35° - 50°, which is formed by a surface including the optical central axis and a reference point of the supporting part side edge of the transition part, and a surface including the optical central axis and in contact with a tip of the supporting part, with a width of the transition part being larger than a width of the supporting part, and a width Wm of the transition part in a middle of the optical part side edge and the supporting part side edge of the transition part being 1.5 times to 3 times of a width Ws of the supporting part.
