Description

Technical Field

[0001] The present application relates to the technical field of pupil measurement instruments, and in particular to a wearable pupil measurement device. Background Art

[0002] A pupillometer is a device used to measure pupil size. It usually consists of a light source and an optical system that can accurately measure the diameter of the pupil and transmit the data to a computer or other recording device. Pupillometry has a wide range of applications in medicine, psychology, and neuroscience, for example in assessing neurological disorders, drug effects, attention, and emotional states. In addition, pupillometry can also be used to study the reaction of the pupil to light and other stimuli, and how the pupil changes under different conditions.

[0003] Traditional pupillometry usually requires users to use it in a specific environment, such as a hospital clinic or laboratory. Wearable pupillometry allows users to measure pupils anytime and anywhere, greatly improving the convenience of use. Wearable pupillometry can monitor pupil changes in real time. For medical or research scenarios that require continuous observation of pupil changes, this real-time performance can provide more accurate and timely data. However, current wearable pupillometry is usually designed as glasses, but due to differences in head shape and eye distance among different patients, eye-type pupillometry is not suitable for all patients and has poor applicability.
