The invention discloses a multifunctional bracelet for managing eye using behaviors of children and teenagers. The wristband comprises a finger clamping type blood oxygen saturation degree testing device, a testing device base, a middle telescopic frame, a base fixing frame, a base and a wristband belt. The blood oxygen saturation degree can be measured through the finger clamping type blood oxygen saturation degree testing device, the finger clamping type blood oxygen saturation degree testing device and the bracelet are integrated, carrying is convenient, under the condition that the hand fears to wear the bracelet, the finger clamping type blood oxygen saturation degree testing device can be pulled out in a sliding mode through the middle telescopic frame, and therefore the blood oxygen saturation degree can be measured under the condition that the bracelet does not need to be taken off. Therefore, the finger can be stretched out to measure the oxyhemoglobin saturation by using the finger clamping type oxyhemoglobin saturation testing device, and the operation is convenient. In addition, a motion monitoring module, a heart rate monitoring module, a blood pressure monitoring module, an illumination detection module, a sitting posture detection module, an outdoor monitoring module and a sleep monitoring module can be integrated in the base, so that multifunctional data monitoring is achieved.
