A pupillometer is a medical device used to measure the size and reactivity of the pupil, often in response to light stimuli. It provides precise, objective data on pupil diameter, symmetry, and dynamics, which are critical indicators of neurological function, ocular health, and autonomic nervous system activity. Pupillometers are widely used in ophthalmology, neurology, anesthesiology, and emergency medicine.

Orthopedic devices are instruments or implants that are used in orthopedic surgeries to replace a bone, support a damaged bone, or replace a missing joint.

A hairbrush is a grooming tool designed to smooth, detangle, and style hair while maintaining its health and appearance. It typically consists of a handle and a head fitted with bristles made from natural, synthetic, or mixed materials. Hairbrushes serve multiple functions, including distributing natural scalp oils evenly along the hair shaft for added shine, stimulating the scalp to promote blood circulation, and reducing tangles and breakage. Different types of hairbrushes such as paddle brushes, round brushes, vented brushes, and detangling brushes are designed to meet specific styling needs, from straightening and volumizing to speeding up blow￾drying. As they are widely used in both personal grooming routines and professional salon settings, hairbrushes remain an essential accessory for everyday hair care and styling.

Hair accessories encompass a wide range of functional and decorative items designed to secure, style, and enhance the appearance of hair, while reflecting personal fashion preferences and cultural influences. They play an important role in everyday grooming routines as well as special occasions, serving both practical utility and aesthetic expression.
