The Portable Handheld Slit Lamp is a compact diagnostic instrument used to examine the anterior segment of the eye in situations where a standard slit lamp is not available. It is especially useful for bedside examinations, emergency care, and outreach eye screening programs. This device provides magnified and illuminated views of eye structures in a portable format. It is typically made of a lightweight high-grade plastic and metal body with optical lenses, LED illumination system, rechargeable battery, and internal electronic components.
