19、bliography . 31 iiiiiForeword (This foreword is not part of American National Standard ANSI Z80.3-2015.)Summary of Changes to ANSI Z80.3 for 2015This 2015 revision represents the most current consensus of experts in this field. Thechanges from the 2010 standard are the result of a thorough study by

20、the ANSI Z80.3committee of the relevance and applicability of its contents.This revision incorporates a continued effort to more properly explain and clarify con-cepts and principles, and to more closely align requirements of this standard withsimilar relevant provisions in existing US and internati

21、onal standards. In addition tominor typographical corrections, changes include: Prism power and imbalance are now defined only for finished products in theas-worn position, since lenses with high base curves and/or significant face-form (wrap) angles must include the proper compensating prism in the

22、 lensblanks to ensure minimal prism in the final product. Luminous transmittance variations and tolerances are now provided in unitsof percent rather than density. Definitions of reference point, special purpose lenses, and polarization axistolerance are added. Minimum luminous transmittance of grad

23、ient tint lenses is modified. A figure demonstrating assessment of cosmetic lens quality is added. Procedure for assessment of frame flammability is amended. Finally, new requirements for frame durability, such as corrosion, materialsafety, and deformation, which already exist in other standards, ar

24、e added.Background and summary of past revisions for ANSI Z80.3Changes made in 2010 were the addition of subclauses addressing resistance to ra-diation; revision of the photosensitive lens qualification test; addition of the definitionof polarizing efficiency; correction of the equations for the cal

25、culation of mean trans-mittance; addition of country of origin labeling; and addition of an equation to theNotes under Table 5.The purchasers and users of nonprescription sunglasses and fashion eyewear needto be assured of certain minimum levels of performance and quality in these prod-ucts. These a

26、re either implicit expectations in the product performance, or safety.The purchaser of the product does not ordinarily have the means to properly assessthese characteristics.In order to accomplish these goals, it is necessary to establish commonly accepteddefinitions, equations, sources, and methodo

27、logy so that manufacturers can produceproducts to meet the standard.This American National Standard specifies impact-resistant characteristics; cosmet-ic, refractive, and transmittance properties of lenses; and the flammability and dura-bility of frames and lenses.Cosmetic, refractive, transmittance

28、, and frame properties specified herein are intend-ed as guidelines, and therefore they are subject to revision since there is a need tostudy further the validity of these property specifications as related to actual normaluse requirements.The Z80.3 Subcommittee was organized in December 1970 and ha

29、d its first meetingon January 7, 1971. The committee usually meets formally twice per calendar year,ivand members review material by email, phone, or fax throughout the year. Workinggroups may be formed to investigate specific projects.This standard contains one annex, which is informative and is no

30、t part of this stan-dard.Suggestions for improvement of this standard will be welcome. Suggestions shouldbe sent to The Vision Council, 225 Reinekers Lane, Suite 700, Alexandria, VA22314.This standard was processed and approved for submittal to ANSI by the AccreditedStandards Committee Z80 (ASC Z80)

41、ble of withstanding an impact test The ability of a lens to withstand impact as determined by 100% testing or by testing of a statistically significant sample (for example, conforming to the requirements of ANSI/ASQC Z1.4) of each production batch, or at the option of the manufacturer, as an integra

42、l part of the manufacturing process. Capability of withstanding an impact test is determined by testing at any feasible stage of manufacture, as described in 5.1.1 and 5.1.2. 3.2 Reference point The point on a lens blank, unmounted lens, or finished lens at which refractive properties, and around wh

43、ich transmittance properties, are specified and measured. 3.2.1 Intended visual axis When specified, the point on a lens coincident with the wearers interpupillary distance or other known or presumed line of sight. 3.2.2 Geometric center When the intended visual axis is not specified, the geometric

44、center shall be the reference point. The geometric center is the point midway between the two vertical tangents and midway between the two horizontal tangents of the edges of a finished lens. For a one-piece or goggle lens intended to cover both eyes, the vertical midline of the lens may be used to

45、determine the geometric center of the portion of the lens for each eye. 3.3 Lens fracture A lens is considered to have fractured when it cracks through its entire thickness and across a complete diameter into two or more separate pieces, or when any piece of lens material visible to the naked eye be

46、comes detached from the ocular surface, or if the test ball passes through the lens. 3.4 Lens types 3.4.1 General purpose lens A lens whose nominal luminous transmittance is at least 8% and that allows the apparent chromaticity of Standard Illuminant D65, when viewed through the lens, to fall within

47、 the boundary for daylight (4.10.2.1 part 4, and Figure 1). 3.4.2 Gradient tint lens A lens whose luminous transmittance varies significantly across the lens. 3.4.3 Photosensitive lens A lens whose luminous transmittance or color, or both, depends on the recent exposure history of the lens. 3.4.4 Po

48、larizing lens A lens whose luminous transmittance varies with the amount and orientation of the polarization in the incident light. ANSI Z80.3-2015 4 3.4.5 Special purpose lens 3.4.5.1 Strongly colored lens A lens that causes the apparent chromaticity of Standard Illuminant D65, when viewed through

49、the lens, to fall outside of the boundary for daylight (4.10.2.1 part 4, and Figure 1). 3.4.5.2 Very dark lens A lens whose nominal luminous transmittance is between 3% and 8%. 3.4.6 Uniform tint lens A lens whose luminous transmittance does not vary significantly over the area of the lens. 3.5 Noncorrective impact-resistant lenses Glass lenses, plastic lenses, or laminated glass lenses made impact resistant by any method. However, all such lenses shall be capable of withstanding the impact test described in 5.1. 3.6 Production batch An identifiable group of len
