Eye scanning is a technology that uses cameras and sensors to capture detailed images of the eye. This process can identify unique patterns in the iris, which are as distinctive as fingerprints. Eye scanning is often used for security purposes, such as in biometric authentication systems, allowing individuals to access secure areas or devices. In addition to security, eye scanning can also be used in medical settings to monitor eye health. By analyzing the images captured, healthcare professionals can detect conditions like glaucoma or diabetic retinopathy. This non-invasive method provides valuable information for early diagnosis and treatment.
