Adjustable Retinoscopy Training Eye - Diopter Design, Optometry Teaching Tool,Schematic Model for Optical Retinoscopy Practice,Imitative Eye

• Accurate diopter: Our schematic eye boasts precise diopter measurements, with an error margin of less than 0.25 Diopter units. It can be adjusted within a range of +4.00D to -5.00D.
• 3 pupil sizes: Our model eye offers three difficulty levels featuring varying pupil sizes: φ3, φ5, and φ7, corresponding to small, regular, and dilated pupils respectively.
• Precise and clear axial angle: Degree of astigmatism axial angle disk: 0~180 degrees, each line represents 5 degrees, and all are accurate and clear.
• Adjustable angle: The angle of our model eye can be adjusted over 90 degrees by manipulating the shaft screw, accommodating practitioners of varying heights for practice and operation.
• 3 layers of arc grooves: Our schematic eye features three layers of arc grooves at the front, designed for the placement of optometric lenses or the setting of astigmatism and axial cylinders presets.
