highest impact among all lens materials, are light in weight, and will also be coated to become scratch-resistant. A glass made with Plastic CR39 is resistant to solvents and weighs less than half the weight of glass and meets the ANSI standards for safety glasses. Anti-reflective coating reduces distracting lens reflections and for that reason may be desirable for certain activities that want safety eyewear.
- Testing can involve primary and high impact tests
- These include a U.S. civilian standard (ANSI Z87. 1 – 2010), a U.S. military standard (MIL-PRF-31013), and a European standard (EN166, 169, 170 & 172).

Consider the front of the safety frame and the temples to get these markings. They will are the manufacturer/brand name or abbreviation plus the frame measurements. QIMA’s Q1 figures for inspection and audit demand certainly are a reflection of the sourcing trends that will continue shaping global trade through the entire rest of 2017.
One reason these tests have become so specialized through the years is due to the American National Standards Institute , among the leading drivers for both U.S. and international safety standards. Past updates to the ANSI Z87.1 standard have focused on product performance and harmonizing with International Safety Equipment standards. They’ve managed to get easier for users to select the correct safety gear in line with the potential hazards and complications their environment produces. The 2015 update also clearly defined UV radiation and addressed issues linked to emerging technologies. The company I work with insists that all protective eyewear should be Z87+ compliant. Is Z87.1 the same as Z87+, and when so, where is that standard identifying that they are the same (I could only find the 2003 edition of the ANSI Z87.1 standard). Testing, performance, and marking criteria for lenses with anti-fog properties were added, since fogging can impede a wearer’s capability to perform work safely.
Eye protection that’s Z87.1 compliant is marked with “Z87.” All safety eyewear manufacturers should provide product information around how their safety eyewear meets these current standards. Over-prescription safety glasses can offer different coatings and tints, and lastly, they can also work with safety glasses fitted with the prescription lens inserts. These glasses are equipped with the prescription then inserted on the trunk of the individual’s preferred safety wear. Make sure to choose anti-fog glasses if varying temperatures and high humidity are regular concerns. Eyeglasses manufactured from polycarbonate have built-in UV radiation filtering ability, have the
The ANSI Z87.1 certification covers the specifications for safety eyewear at work, to safeguard both workers and employers from workplace injuries and their effects.

The first marking you’ll likely see on your own eyewear is “Z87” or “Z87+”. This is the ANSI standard for impact which helps ensure safety eyewear provides workers with the needed protection from impact hazards. They are seen by changes in transmittance allowances to identify the initial properties of wrap lenses and expanded welding filter shades.

Criteria and requisite markings for protectors offering relaxed optics were added being an substitute for long-standing requirements. In accordance with Prevent Blindness America, every year a lot more than 700,000 Americans injure their eyes at the job, and another 125,000 injure their eyes at home.

In order to be eligible for the ANSI certification, lenses must withstand the weight of a 1.1 lb pointed projectile dropped from a height of 50”. In the second test, lenses and frames must withstand the impact of a .25” diameter steel ball fired at 150 FPS, the High Velocity Impact Test. Face shields protect against potential splashes or sprays of hazardous liquids. When worn for protection against UV, must be
But remember that AR coating may affect the impact resistance of certain lenses, so impact resistance tests must occur following the coating is applied. Your eye care professional might need to verify that the optical lab did indeed test the lenses properly for impact resistance after applying the coating. If you don’t require prescription lenses, or you wear contacts, you can buy non-prescription safety eyewear from most hardware, building supply and sporting goods stores. 1 part of ANSI standards references the standards for Occupational and Educational Personal Eye and Face Protection Devices. These standards help ensure that personal eye and face protection devices supply the necessary protection from impact, non-ionizing radiation, and liquid splash exposures.
