GB/T 13511.3-2019Assembled spectacles -- Part 3: Single-vision near-vision spectacles (English PDF)

Foreword

"Fixed Glasses" is divided into three parts.

---GB 13511.1 fitting glasses Part 1. single light and multi-focus;

---GB 13511.2 fitting glasses Part 2. Gradient coke;

---GB/T 13511.3 fitting glasses Part 3. single light presby mirror.

This part is the third part of "Fixed Glasses".

This section uses the redrafting method to modify the use of ISO 16034.2002 "Ophthalmic optical single-light near-reading glasses specifications."

This part has a structural adjustment compared with ISO 16034.2002, adding the corresponding chapter number and figure number extension of Chapter 5 and Figure 1.

The technical differences between this part and ISO 16034.2002 and their reasons are as follows.

---About the normative reference documents, this part has made technical adjustments to adapt to China's technical conditions, adjustments

The situation is reflected in Chapter 2, "Regulatory Citations", and the specific adjustments are as follows.

* Replaced ISO 8980-1.1996 with GB 10810.1 modified to adopt international standards;

* Replaced ISO 12870.1997 with GB/T 14214 modified to adopt international standards;

* Replace ISO 13666.1998 with GB/T 26397 modified to adopt international standards;

* Added reference to GB 10810.3;

* Added reference to QB/T 2506;

* Removed ISO 7998.1984, ISO 8624.1991 and ISO 14889.1997 referenced by ISO 16034.2002;

--- Chapter 1 removed "The glasses are not suitable for regular use without the approval of eye care professionals";

--- Added terms and definitions "optical center horizontal distance" "optical center horizontal deviation" "optical center one-sided horizontal deviation" and "light"

The center of the school is vertically different" (see 3.2~3.5);

---4.1 General requirements increase the light transmittance of the lens;

--- 4.2 The top power range of the lens is modified to "within 1.00m-1~ 4.00m-1 (1.00D~ 4.00D)";

--- Increased 4.3 "the difference between the two lens tops";

--- Amend the 4.4 heading "Design Datum Point and Prism" to "Optical Center" and modify the technical requirements;

--- Added Chapter 5 "Measurement Methods";

---6.2 added a). "product name, model, manufacturer or supplier name and address; implementation standards and certificate, date of manufacture

Or production batch number."

This section has the following editorial changes.

--- In line with China's technical standards system, the standard name was changed to "fitted glasses part 3. single light and old mirror into a mirror";

--- Replace the "single-view near-view mirror" with the term "single-light presby mirror";

--- Change the title of Chapter 4 "Performance Requirements" to "Requirements";

--- Replace the title of Chapter 6, "Marking, indications and warnings on glasses" with "flags";

--- Added "may be abbreviated or graphical representation" in 6.1a);

--- Replace the 6.2 heading "Description and Warning on the Package" with "Identification";

--- Change Chapter 5 "Center Distance" to "Optical Center Horizontal Distance";

--- Added the International System of Units for the unit of the top power.

This part is proposed and managed by the China Light Industry Association.
