• 【Precise and Clear Axial Angle】 The astigmatism degree axial angle disk is adjustable: 0~180 degrees, each line represents 5 degrees, all precise and clear. Suitable for calibrating optometers, optometrists, and school teaching.
• 【Adjustable Angle】By adjusting the axial screws, the eye angle of our model can be adjusted more than 90 degrees, which is suitable for practitioners of different heights to practice and operate.
• 【3 Layers of Curved Grooves】 The front of the model eye has three layers of curved grooves, which can be used to place optometry lenses or preset astigmatism and axial cylinders. Convenient for your measurement
• 【Multiple Pupil Sizes】 AISITESYour eye model has three difficulty levels with different pupil sizes: 3, 5, 7, which can simulate small, normal and dilated pupils.
• 【Accurate Refraction】The refraction of our modeled eye is very accurate, with an error of less than 0.25 units of D. The eye can be modeled with a variety of pupil sizes.
