The Vision Screener (Photo screener) is a portable diagnostic device used for quick vision screening, especially in children and non-cooperative patients. It captures images of the eyes to detect refractive errors, eye alignment issues, and risk factors for amblyopia (lazy eye). This equipment is commonly used in ophthalmology clinics, pediatric clinics, schools, and community screening programs. It is typically made of a lightweight high-grade plastic body with optical lenses, camera system, infrared illumination, rechargeable battery, and internal electronic components.
