Abstract: PURPOSE: To attain near view and far view respectively by providing a diffracting component, which has various phase contours, with at least two concentric areas. CONSTITUTION: At least, two concentric areas 110 and 120 which have various phase contours are provided so as to cause diffraction of various degrees. The diffracting component is formed of a phase hologram by adjusting a relief or index. Further, the diffraction of a lens 10 and the concentric areas 110 and 120 are accompanied by a refracting element determined by the size and shape of the lens 100, and the refracting component is formed by the difference in radius of curvature between two main surfaces 130 and 140 of the lens. Namely, A diffracting efficiency ratio is obtained for far view and near view and varies as a function of a pupil diameter. Consequently, the new view with high illuminance and intermediate-distance and far view with low illuminance are possible.

Abstract: The hydrogels consist essentially of the polyurethane of polyoxyethylene. The crosslinking is carried out by a reaction of a polyfunctional isocyanate with the polyoxyethylene in solution in a non-aqueous solvent. Transparent hydrogels are obtained, having a high swelling ratio in the presence of water and good mechanical properties.

Abstract: The invention concerns a process and device for measuring the degree of ametropia of an eye. The rays of a luminous source passes through a focussing lens and a test lens in order to create an image on the retina. The rays issuing from the source or from the image pass through a black optical slit and are reflected by at least one reflecting surface defined in a revolving screen driven in rotation by a motor. Application to refractometric instruments for measuring the degree of ametropia of the eye.

Abstract: The present invention relates to an apparatus for eye sight examination, allowing to test both of the patient's eyes, especially to detect his common failures and vision defects, for far and close vision, and eventually intermediary distance vision. The test-image are borne by at least one ribbon or band mounted in a block of two winding spools, housed in a body forming an easily removable tape box of an adequate support of body of the apparatus. The invention applies to the automatic or semi-automatic detection of visual defects of a patient.
