摘要: Eye prescriptions may be determined by providing a simple, easy to use, portable device with a specially configured targeting light source that aligns the eye, mitigates accommodation, and provides accurate results. Unlike stationary, closed view autorefractors, this device typically is portable, self-usable, relatively inexpensive, enabling more widespread use across the world.

摘要: A miniaturised instrument for simulating simultaneous vision by generating masks is provided with a single image-forming optical channel. The instrument comprises: a mask-generating element (EGM) which generates at least two complementary masks, with a temporal frequency of alternation such that when one partially blocks the incident light, the other allows the incident light to partially pass, and vice-versa; an adjustable lens (LA) of variable optical power which generates, with said frequency of alternation, at least two different optical powers corresponding to at least two observation distances. The EGM and the LA are located in a single optical channel via which the incident light circulates, such that each mask of the EGM is temporally synchronised with a power of the LA. The combination of all the masks and optical powers produces, via high-speed temporal fusion, a pupil pattern wherein at least two optical powers corresponding to at least two observation distances are combined.

摘要: The invention relates to a miniature simultaneous vision simulator instrument with various image-forming channels, each one of which projects, onto the retina of the same eye, a component image with a different degree of defocusing of the same observed object, such that the superposition of all of the component images forms a final simultaneous vision image on the retina of the eye. The instrument has at least one adjustable variable focus lens that, as the focus is changed, modifies the vergence of the light beam passing through said adjustable lens. Furthermore, one of the image-forming channels passes through the adjustable variable focus lens. The instrument can operate in the modality of optical channels that are physically differentiated in the modality of temporal channel multiplexing.
