    Abstract: PROBLEM TO BE SOLVED: To realize a correction most suitable for a foresighted person by using a range consisting of different lenses limited in numbers. SOLUTION: Two lenses among a pair of lenses for presbyopias are gradually changing and simultaneous visual acuity types, and its gradually changing profile changes so that a refractive power of the center is larger than the circumscription in one lens and is the reverse in the other lens. The range 1 consisting of lenses consists of lenses 2A-2Z and 3A-3Z which make two continuous columns 2 and 3, and their appellative refractive powers differ by a prescribed unit, for example, by 0.25 diopters. The method of prescribing a lens pair has a step for performing a standard visual acuity measurement and inspecting method, a step for deciding whether which eye is good in tolerance against a defocus due to the presbyopia and a step for selecting a lens suitable for each eye from each column of the range according to the inspected result.

    Abstract: PROBLEM TO BE SOLVED: To provide a progressive multi-focal ophthalmologic lens where the relation between progression of the spherical aberration of eyeballs due to aging and a refraction abnormality is taken into consideration. SOLUTION: In this multi-focal ophthalmologic lens 11, the visual profile (unit: diopter) of the lens as a function of height (k) (unit: mm) on an axis A of the lens and the addition (Add) corresponding to the degree of presbyopia of a user is defined by P(h)=f(PVL, Add, h) +C(Add, PVL)h2 +B(Add,PVL) where PVL, (f), C(Add, PVL), and B(Add, PVL) are the vision (unit: diopter) required for far sight, a function of evolution between near vision and far vision, a spherical aberration correction coefficient determined by the addition and the far vision, and a vision correction coefficient determined by the spherical aberration coefficient. respectively.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for determining the shape of a contact lens which is capable of correcting the aberrations of a high degree measured with the patient's eye by limiting the occurrence of the undesirable aberrations when the lens is worn to the eye and is adapted to meet individual characteristics. SOLUTION: This method includes a step of measuring the optical aberrations of the eye to be corrected, a step of determining the shape of the back of the lens from the determined anatomical area of the cornea in order to obtain a prescribed mechanical behavior of the lens when the system is placed above the eye, a step of measuring the optical aberrations of the eye to be corrected and a step of determining the shape of the front of the lens from the measured optical aberrations of the eye combined with the data relating to the shape determined with respect to the back of the lens in order to correct the aberrations. This system has a measuring unit for measuring the anatomical area and aberrations of the eye and an electronic computation unit.

    Abstract: The contact lens (10) has one or more projections (12) on its outer surface (11) to interact with the wearer's eyelids. Each projection is elongated and curved in shape, following the line of the perimeter of the lens, and has sloping ends and a flat top. The angle covered by the flat top of a projection is equivalent to half the angle covered by the whole projection. The thickness of each projection is between 0.2 and 0.24 mm, and the radius of the arc of its centre line (L) is between 0.7 and 0.9 of the radius of the lens, and it covers an angle of between 60 degrees and 150 degrees .
