Abstract: An optometric apparatus and an optometric method which perform an accurate eye examination on people who have a wide range of refractive powers with astigmatism, myopia or hyperopia, and which are also applicable especially to those with mixed astigmatism are provided. The apparatus performs a subjective eye examination by prompting a subject to view test symbols displayed on a computer screen by one of the right and left eyes at a time.

Abstract: A system and method for determining an eyeglass/contact lens power is provided, which can determine the power of an eyeglass/contact lens that is suitable for an individual. The eyeglass/contact lens power determination system (20) according to the present invention comprises inputting means (202) for entering information on the condition of a subject's eye, means (204) for determining an optical eyeball model corresponding to the information on the eye condition entered through the inputting means (202), and means (218) for selecting a lens power for verifying the focal power of an eyeglass/contact lens worn by the subject using the optical eyeball model determined by the optical eyeball model determining means to select a lens power.

Abstract: A spectacle and contact lens selecting system includes an input unit for inputting information related to a state of eyes of a user, an eyeball optical model deciding unit for deciding an eyeball optical model corresponding to the information related to the state of the eyes input by the input unit, an eyeball accommodation range determination unit for examining optical performance of an eyeball within a range of accommodation of the user in the decided eyeball optical model to determine the range of accommodation of the eyeball, a lens power selecting unit for examining optical performance when the user wears spectacles or contact lenses to select a lens power, and a wearing state display unit for displaying a wearing state of the spectacles or the contact lenses to be selected.

Abstract: An optometric apparatus and an optometric method includes the steps of acquiring subject's attributes and an orientation selected by the subject on an astigmatic axis determination chart displayed on the computer screen, displaying vision measurement charts in the acquired orientation and the orientation perpendicular thereto to acquire visual recognition limits selected by the subject, calculating far point distances based on the acquired visual recognition limits and the acquired subject's attributes, and calculating a refractive power based on the acquired orientation and the calculated two far point distances. The far point distance is calculated using a neural network that has been determined by a number of subjects in advance.

Abstract: A system and method for remotely ordering and purchasing eyeglasses via a network includes a user interface unit, an eyeglass ordering and marketing service center, and a network that connects therebetween. The system includes an eyeglass frame selection unit for selecting eyeglass frames from among a plurality of eyeglass frames in response to user input, a unit for creating display information concerning eyeglass frames, a unit for testing the vision of the user, and an eyeglass lens selection unit for selecting lenses from among a plurality of eyeglass lenses in response to user input. The system also includes an eyeglass ordering and marketing processor wherein the frame selection unit, the vision test unit, and the lens selection unit performing a vision test in response to the requirements of the user. Appropriate eyeglass frames and eyeglass lenses are determined which best fit the user.

Abstract: In an optical frame attachment according to the present invention, a flexible tangle preventing member 4 is attached so as to couple a predetermined portion 2b anterior to a part 2a of a temple, where an ear contacting portion 3a is attached, and a front end 3c of the ear contacting portion 3a; and is attached so as to couple the temple 2 and the front end 3c of the ear contacting portion 3a even when the temple 2 is lifted upward upon taking off glasses. Since a space between the temple 2 and the front end 3c of the ear contacting portion 3a is blocked by the tangle preventing member 4, even when the temple 2 is lifted upward upon taking off the glasses, the hair is less likely to enter an oscillating portion 3b serving as an attaching portion of the temple 2 and an ear pad member 3, and tangling thereto is suppressed. Further, since the tangle preventing member 4 has flexibility, the function of suppressing the slipping down of the glasses are not inhibited.

Abstract: A rimless eyeglasses lens-installing apparatus, a connector connects a lens to a lug and a fastening tool fixed the lens and the connector to each other. The fastening tool has a first fastening member and a second fastening member. A metal insertion member having a threaded hole formed thereon is disposed in an internal portion of the first fastening member by insert molding. An outer threaded portion of the first fastening member engages a threaded portion of a lens through-hole. The threaded portion of the second fastening member is screwed into the threaded hole of the insertion member. A portion of the first fastening member projecting from a rear surface of the lens is cut off appropriately.

Abstract: A pair of eyeglasses includes a lens having through-holes near both edges thereof. A lug connected to a temple is installed at one end of the lens. A connection member having a lens-holding portion, a columnar member and a supporting piece is formed at one end of the lug. The outer diameter of the columnar member is substantially equal to the inner diameter of the through-hole of the lens, and the distance between the inner side of the supporting piece and the columnar member is substantially equal to the distance between the end of the lens and the through-hole. A flexible washer is interposed between the head part of the fastener and the lens. A connection member is disposed at an end of a bridge, which is installed at other end of the lens.

Abstract: An eyeglasses lens-installing apparatus includes a lens. A substantially elliptical through-hole is formed in the vicinity of an edge of the lens. A substantially elliptical columnar member disposed on a lens sandwiching part of a connection member is fitted into the through-hole from one main surface side of the lens. The columnar member has a hole formed therein. A screw portion is provided on the inner peripheral surface of the hole of the columnar member. The columnar member is integral with the lens sandwiching part and the lug. A fastener is inserted into the through-hole from the other main surface side of the lens. The fastener includes a fixing part having a male screw portion disposed on the periphery thereof and a head part. The fastener is inserted into the through-hole, with a close-contact member installed on the periphery of the fixing part. At this time, the fixing part of the fastener is screwed on the screw portion of the columnar member.
