Prescription Safety Frequently Asked Questions
What are the lenses made from?
The lenses are made from polycarbonate with a minimum 2mm centre or edge thickness for medium impact eye protectors. The lenses for low impact eye ptotectors are made from minimum 1.5mm centre or edge thickness polycarbonate . Polycarbonate is the unbreakable plastic lens material. It is coated with abrasion resistant coating on both curves. We can also supply CR39 in thicknesses of 3.0mm CT, but these are for low impact product only and only until the endorsement of the new standard.
Are there any restrictions on frames which can be used for safety spectacles?
Absolutely !! All frames must have passed independent tests by a NATA registered laboratory. Our frames have all been tested at Unisearch (the University of New South Wales Optics and Radiometry laboratory) The product must then be approved by the regulatory body , SAI Global and placed on a StandardsMark Schedule. Rx Safety will not fit lenses into unapproved frames for prescription safety spectacles.
What frames do you have which are on a StandardsMark Schedule?
We can supply a range of frames including the Hilco Leader, Cummings Optical, Uvex and Ugly Fish Safety range of frames which are approved for the industrial safety standard AS/NZS 1337.
We have just received certification for AS/NZS 1337.6 and we will soon have a range of frames meeting the stringent requirements of the new standard.
Do you have frames in stock ready to go?
We have stocks of these frames and it will save you freight money to simply fax your order through to us and we can pick a similar frame from our frame stock and start the job immediately.
What Australian standards does the Prescription Safety product meet?
The Rx Safety product meets the requirements of AS/NZS 1337. and AS2228.1 in accredited NATA registered laboratory tests. Rx Safety is licenced by SAI Global to make certified prescription safety eye protectors.
What documentation will I get?
You will receive a certificate with each job testifying that the product meets the standard and this certificate will be signed by an approved signatory.
Can I edge lenses for safety spectacles in my own workshop?
You can make spectacles in your workshop but you cannot claim that you meet the prescription safety standard unless you have had successful independent testing at a NATA registered laboratory to ensure product compliance. If in doubt contact SAI Global and ask for Kevin King ( Project Coordinator)
What is the power range for Medium Impact Prescription safety models?
The script range which we offer to conform to AS/NZS 1337.6 is +3.00 to a –6.00 out to a –2.00 cylinder curve. We can make the product for you outside this range using the same machinery but it will not be certified and will be issued as a compliant job only.
What is the difference between Certified and Compliant?
Prescription protective (safety) eyewear in Australia is governed by Australia/New Zealand Standards (AS/NZS) 1337.6:2012, “Personal Eye Protection – Part 6: Prescription Eye Protectors Against Low and Medium Impact,” which in turn references AS/NZS 1337.1:2010:, “Eye Protectors for Industrial Applications.”
There are 2 levels of impact protection under AS/NZS 1337.6:2012 being Low Impact and Medium Impact which we make.
Low Impact – these need to pass a low impact drop-ball test regimen, and side shield protection is not mandatory, note that it is our policy that side shields where part of a safety frame are always supplied with the spectacles.
Medium Impact – requires permanently attached side shields or frame design to ensure proper ocular coverage and these need to pass Ballistics testing at 40-41.5 m/sec, in combination with a number of other tests
There is a annual surveillance audit of our manufacturing process, machinery calibration , product traceability and procedures which is carried out by an auditor from SAI Global.
Rx Safety makes a mixture of product which is certified and compliant to AS/NZS 1337.6.
Rx Safety uses precisely the same manufacturing process to make all product.
