Model: MCR-800
The MCR-800 Visual Screener uses ultrasonic ranging, crossover, flash and sound technology to accurately detect refractive errors in different populations and then identify possible potential refractive problems.
The MCR-800 Visual Screener has many advantages, such as portable, fast and accurate testing, no contact and no damage to the eyes. It is suitable for refractive examination in a large number of people because 5 seconds is enough for binocular testing. We all know that the state of refraction is very important for children, because if the doctor can't find long-term refractive error and correct cure, then the child will one day unfortunately become amblyopia or lose the best chance to treat lazy eyes, and finally become permanent. amblyopia. A special model for child testing is the best way to conduct child screening. Therefore, it is not only suitable for adults, but also for infants and people with disabilities.
