    摘要: The invention relates to an instrument for simulation of multifocal ophthalmic corrections, comprising two optical channels with different optical power values in the beams coming from the object observed, wherein at least one channel comprises a Badal system. This instrument simultaneously provides images of objects near and far focused. The system provides the same optical magnifications for each channel, regardless of the optical power thereof, and produces superimposed retinal images with different degrees of focus which, unlike other devices, are all of the same size. The instrument allows simulating different optical powers for near vision and different refractive corrections for distant vision.
