The introduction of Face ID by Apple in 2017 revolutionized the way we unlock our iPhones. This facial recognition technology uses advanced machine learning algorithms to map and recognize the unique features of a user’s face. However, one question that has sparked debate among iPhone users is whether it’s possible to open Face ID with eyes closed. In this article, we’ll delve into the world of facial recognition technology and explore the answer to this question.
How Face ID Works
Before we dive into the main topic, it’s essential to understand how Face ID works. Face ID uses a combination of cameras and sensors to map and recognize a user’s face. The technology consists of the following components:
- TrueDepth Camera: This camera projects 30,000 infrared dots onto the user’s face to create a 3D map of their facial features.
- Infrared Camera: This camera captures infrared images of the user’s face, which helps to detect the presence of a face.
- Flood Illuminator: This component emits infrared light to help the TrueDepth camera capture images in low-light conditions.
- Dot Projector: This component projects the 30,000 infrared dots onto the user’s face.
When a user attempts to unlock their iPhone using Face ID, the TrueDepth camera captures a 3D map of their face and compares it to the stored facial data. If the two match, the iPhone is unlocked.

Can Face ID be unlocked with eyes closed?
Face ID, the facial recognition system used in Apple devices, is designed to provide secure biometric authentication. However, there have been concerns about its ability to be unlocked with eyes closed. According to Apple’s documentation, Face ID is designed to work with the user’s eyes open, and it uses a combination of 3D mapping and machine learning algorithms to verify the user’s identity.
While it is theoretically possible to unlock Face ID with eyes closed, it is highly unlikely. Face ID requires a clear view of the user’s face, including their eyes, to function properly. If the user’s eyes are closed, the system will not be able to detect the unique characteristics of their face, and the unlock attempt will fail. Additionally, Apple has implemented various security measures to prevent unauthorized access, including a feature that requires the user to look at the screen to unlock the device.
How does Face ID detect eyes closed?
Face ID uses a combination of infrared and visible light cameras to detect the user’s face and verify their identity. The system is designed to detect the unique characteristics of the user’s face, including the shape of their eyes, nose, and mouth. When the user’s eyes are closed, the system will detect the change in the shape of their eyes and the surrounding facial features.
The infrared camera in Face ID emits a series of infrared dots that are projected onto the user’s face. These dots are then detected by the camera, creating a 3D map of the user’s face. If the user’s eyes are closed, the system will detect the absence of the usual eye shape and the presence of the eyelids, which will prevent the device from unlocking. This technology allows Face ID to accurately detect when the user’s eyes are closed and prevent unauthorized access.
Can Face ID be fooled by a photo or mask?
Face ID is designed to be highly secure and resistant to spoofing attempts. The system uses a combination of 3D mapping and machine learning algorithms to verify the user’s identity, making it difficult to fool with a photo or mask. According to Apple, Face ID is designed to detect the unique characteristics of the user’s face, including the shape of their eyes, nose, and mouth.
While it is theoretically possible to create a highly realistic mask or photo that could potentially fool Face ID, it would be extremely difficult and unlikely to succeed. Face ID requires a clear view of the user’s face, including their eyes, to function properly.
