slit lamp

A slit lamp is a specialized microscope used by eye doctors to examine the front parts of your eye, such as the eyelids, cornea, iris, and lens. It provides a detailed, magnified view, allowing the doctor to detect issues like infections, injuries, or eye conditions. The device emits a thin, bright beam of light—like a slit—hence the name, which can be adjusted to see different depths and structures. This examination is quick, painless, and essential for diagnosing and monitoring eye health.
