CONSTITUTION:The kind of a frame (synthetic-resin made, metallic, nylon-yarn fixed, etc.), the shape of the frame (distance between frame center, noise witdth, lateral width and longitudinal width of one eye, etc.), position information on a lens prescription value in the frame, i.e., and pieces of information on distance between user's corneal peaks, optical center of the lens, arrangements of the near view area of a multifocal lens in the frame, etc., are obtained at an optician and those are inputted to a manufacture factory through online transmission by using a computer, etc. Those abundant data on the frame shape is inputted to the computer for supplying lenses with optimum thickness; abundant data such as distance data from a frame center O to plural points n1-nn are inputted and outputted, article number by article number, simularity of design and size are inputted and the frame drawn on a lattice-shaped chart to obtain data, etc. is inputted and outputted.

Description

【発明の詳細な説明】 本発明は眼鏡レンズの供給方法に関し、各々の眼鏡装用

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for supplying eyeglass lenses, and an object of the present invention is to provide all eyeglass lenses having an optimal wall thickness for the type and shape of eyeglass frames used by each eyeglass wearer. .

現在、世界各国に於いて、眼鏡レンズ全供給する方式は
大別し′″c2つの方式に分類される。
Currently, in countries around the world, the systems for supplying all spectacle lenses can be broadly classified into two types.

One is that the eyeglass store informs the prescription value of the lens to the manufacturing factory or lens wholesaler of the JP type, obtains all lenses made of fabric that does not have the fringe finish, and then frames them into the eyeglass frames used at the eyeglass store. This is a method in which all inserting and finishing is done, and it is used for kings in Japan, Asia, Europe, etc., and is called the uncut method.

The other one is an eye test doctor (optomθtr1st)
The company transmits the prescription value and type of the lens, as well as the position information of the lens prescription value within the frame to be used, to the lens manufacturing factory, which processes the lenses from manufacturing to frame fitting. This method is commonly used in North America and is called the annoying method, in which the completed product is sent to a visual acuity tester.

点に於いて、アンカット方式と決定的に異なる。
These two methods are sometimes used in parallel, and in the uncut method, there are opticians who carry lenses of the same type, and in the lab method, there are glasses that carry lenses of the 41i type. There are cases where the above classification is not necessarily followed, such as some lens factories that own all of the frames in
In the Tomo 4 method, the lens manufacturing factory understands the type and shape of the eyeglass frame to be used, and can prepare eyeglass lenses with the most suitable thickness for the eyeglass frame. , which is decisively different from the uncut method.

The significance of sizing the eyeglass lens that has the thickness that goes through the eyeglass frame the most is that it exists in relation to lenses.As is well known, in lenses, the center is generally the thickest. , it has a shape that becomes thinner as it goes to the periphery. Therefore, if the same peripheral thickness is set for the same power, the thickness of the center becomes thicker as the outer diameter of the V-lens increases.111
The same goes for the size of the lens frame, and generally a large eyeglass crusher and thick lenses are required.

However, cheek implants that are uncut or prepared for the same power are generally only 2.6 dia. , we have no choice but to use a lens with a larger outer diameter than necessary, which leads to the need for a lens that is thicker than necessary.
This is mandatory for all glasses wearers.

As a way to improve this shortcoming even a little, there is a method called open outer diameter designation, in which the lens factory measures the minimum outer diameter of the eyeglass frame at ℃ and specifies it to the lens factory. However, even circular lenses such as astigmatism lenses, Norism prescription lenses, progressive multifocal lenses, etc. are opaque to lenses whose peripheral thickness varies depending on the direction.

In this regard, in the laboratory method, as mentioned above, the lens factory must understand the type and shape of the eyeglass frame to be used.
Therefore, it is possible to manufacture all eyeglass lenses with the most suitable thickness for each eyeglass frame. However, in the laboratory method, there is a step of transporting a frame with a high sieve value, so there is a drawback that there is a large risk of damage or loss.

In addition, in a market where the uncut method is the mainstream, such as the current Japanese market, for example, the full introduction of the annoying method means that the lens manufacturing process, which occupies a large proportion of the frame-fitting process in eyewear Jg, will be eliminated. This would be a situation in which the factory side would take away the money, which would be difficult to accept.

In view of this point, the present invention is based on a new idea that has not existed in the past, has the advantage of the laboratory method even in the market where the uncut method is the mainstream, and eliminates all the above-mentioned drawbacks. We aim to provide a new spectacle lens supply method.

The data of each distance in n3...nn marks becomes data representing the shape of one eyeglass frame, and such data is assigned a product number for each eyeglass frame of multi-frame type and stored in the °C computer. There is. Next, the eyeglass store transmits the eyeglass frames selected by each customer, the product number and the aforementioned main dimensions, such as lens size and nose width, to all lens manufacturing factories. There are various means of transmission such as binding, computer online, facsimile, or g=communication.〇(2) There are many types of eyeglass frames depending on their dimensions and thickness, but they can be categorized into one type. If it is divided into several types, such as "eggplant-shaped" and "square-shaped," as shown in Figures 2 (a) and (1), there will be several types.

(3) When you go to an eyeglass store and have a grid-like chart (or a similar measuring device) prepared in advance as shown in 2 in Figure 6, the eyeglass frame is determined according to the wearer's preference. , place the frame 3 at a predetermined position on the chart 2, and move from the frame center 0' to multiple points n1. n2...n
The distance data for each lens are transmitted to the lens manufacturing factory as all eyeglass frame shape data together with the lens prescription value and the eyeglass frame dimension information described in the previous section (2).

That is, rtk is calculated at the thinnest point of "C" in the eyeglass frame, the total thickness of the center of the lens is calculated so that the thickness at that position becomes a predetermined value, and the lens is shaped into a surface shape that gives a predetermined lens prescription value. The desired lens can be obtained by rough sanding, sanding, and polishing.
