Description

Spectral Difference Test System

The present invention relates to a test system for the difference in the degree of spectacles in glasses. The purpose is to introduce a customizable measuring system by introducing an adjustable aperture element, and measure the light refraction caused by the effect of spectacles on the imaging plane element. Offset to detect non-degree glasses such as protective glasses, sunglasses, night vision glasses, and anti-blue light glasses.

Glasses are often limited by the level of processing, and many lenses often have various quality problems. The most common are poor surface finish, spiral, phobia, orange peel, pitting, scratches, streaks, chipping, etc. The above-mentioned quality problems usually lead to deformed, blurred, dizzy, nausea, and even heart discomfort in patients with refractive errors. As a protective product for human eyes, the requirements are mainly: technical indicators of the product's spectral performance, optical power, power, surface quality, flame retardancy, and mechanical strength; here, the United States, Japan, the European Union and International organizations have also established many standard specifications, such as ISO8980-3 for measuring the transmittance of eyewear products; Europe uses EN166-2001 to define general protective eyewear testing, EN167-2001 to define personal eye protection optical tests, and EN168-2001 to define personal eye protection. Optical test, EN169-2002 defines the transmission requirements of human eye protection and related technical filters, and ISO 12312-1 and ISO 12311 test sunglasses related quality standards, among which ISO 12312-1 and ISO12311 specifically define the difference Testing and specifications; the United States uses ANSI Z80.3 to test the relevant quality standards of sunglasses to ensure the quality of the glasses.

The prior art studies on the test of the difference in the degree of spectacles, such as the test method for the imbalance of monolithic sunglasses or covering binocular filters as mentioned in the ISO 12311 8.2.3 specification. This method measures monocular sunglasses The imbalance between the two reference points of the wearing position or the monolithic filter is the difference in degree. The configuration of the reference method is as shown in FIG. 1. FIG. 1 shows a diagram of a conventional spectacles difference test system. FIG. 2 shows a structure diagram of a second aperture element 601 of the conventional spectacles difference test system. Determination of degree difference. Other methods can also be applied, such as using two parallel laser light sources to illuminate, so that it can be measured within the uncertainty range required. The measurement program first irradiates the interference filter element 201 with the light source element 101, and when the eyeglass element 501 is no longer in position, the position can be adjusted to produce a single image on the imaging plane element 801. The eyeglass element 501 is placed on the achromatic lens element 701 and then put on the wearing position. The test is performed on a head shape suitable for the sample. The various tests described in this standard use two sizes of reference head types. The mid-head type approximates a 50th percentile European adult male. The small head is similar to a 12-year-old European child at the 60th percentile. The head shape made with reference to this standard has provisions, and the size of the medium or small head size used should be suitable for the goggles to be measured. Unless otherwise specified by the manufacturer of the eyewear, a medium-sized head shape should be used. Whether the head shape specified for the goggles is appropriate should be confirmed by the testing organization. For all tests on goggles, only the single-scale head type selected should be used. It should be noted that the small head type eye distance is 54mm in width, and the large head type eye distance is 64mm in width, both of which are fixed values. A suitable second aperture element 601 is selected. At this time, the distance between the center of the left aperture 6011 and the center aperture 6012 or the center of the right aperture 6013 and the center aperture 6012 in FIG. 2 is half the pupil distance. It is a circular opening from the central aperture 6012 to the left aperture 6011 and the right aperture 6013 of the second aperture element 601. The typical pupil distance for adult sunglasses is 64 ± 0.4mm, and the typical pupil distance for children sunglasses is 54 ± 0.4mm. Other pupil distances can be selected if required by the manufacturer. Measure the light emitted from the light source element 101 through the interference filter element 201, the achromatic lens element 301, the first aperture element 401, the eyeglass element 501, the second aperture element 601, and the achromatic lens element 701 in order, and finally image On the imaging plane element 801, a vertical distance and a horizontal distance between the displacement images can be measured. The difference between the vertical distance and the horizontal distance mcm / m obtained here shall be divided by two. If the light path corresponds to the horizontal imbalance of the two eye areas, it is said that the carcass is inward. If the light path is not crossed, the carcass is outward. As shown in Fig. 1, the optical path of the dotted line of the imaging plane element 801 does not intersect with the "carcass outwards". If the imaging is not shifted, then the solid line mark and the center dotted line cross on the imaging plane element 801. By measuring the two displacement images of the imaging plane element 801, it is possible to determine the difference in power of the eyeglass element 501. FIG. 2 When the light from the light source element 101 advances to the second aperture element 601, two displacement images can be projected on the imaging plane element 801 through the left aperture 6011, the right aperture 6013, and the central aperture 6012.
