Schematic Eye Model – Ophthalmic Retinoscopy Training Instrument

The Schematic Eye Model is a specialised ophthalmic training instrument designed to simulate the optical and refractive properties of the human eye. It allows optometry and ophthalmology students to practise retinoscopy, assess simulated refractive errors and understand how light is focused within the eye. Featuring an adjustable pupil, simulated retina and trial lens holders on selected models, the instrument helps users practise identifying myopia, hyperopia and astigmatism in a controlled training environment. Suitable for optometry schools, ophthalmology training centres, eye hospitals, medical colleges and clinical teaching laboratories.
