[0002] Computer ophthalmometer is a vision ophthalmometer, which is used to check the convergence of light after it enters the eyeball. Computer ophthalmometer is an objective ophthalmometer, and its principle is basically the same as that of retinoscopy. It uses infrared light source and automatic fogging device to relax the eyeball adjustment, and uses photoelectric technology and automatic control technology to check the diopter. Computer ophthalmometer can be used for diagnostic ophthalmology for soft corneal contact lens fitting. It usually takes a few seconds to a few minutes to measure a person being tested, and can quickly measure the degree of refractive error, providing more accurate diopter and pupil distance for lens correction.
