TESTING FOR OCCUPATIONAL SAFETY GLASSES

U V P R OT E C T I O N

UV exposure is threat to eyesight and can be amongst one of

the most common risks that an employee is subjected to.

Should a person be exposed to UV without adequate

protection, they are likely to experience serious eye damage

which can include retinal issues, lens opacity, and can

irreversible sight loss.

S C AT T E R E D L I G H T/ S T R AY L I G H TThis light scattering reduces the contrast of the image

projected on the retina, thus decreasing the quality of vision.

A lens can be tested for Stray light by using a laser beam which

is shone through the lens at a determined angle. The laser

beam is then picked up using a radiation receiver and is

assessed for deviation of the beam to ensure it is within the

tolerance level.

L I G H T T R A N S M I T TA N C E

A spectrophotometer is used to quantitatively measure the

transmission and reflection of visible light, UV light or infrared

light. Spectrophotometers measure intensity as a function of

the light sources wavelength. For glasses which are used for

mechanical or chemical hazards, the light transmission must be

higher than 74.4%.

R E F R AC T I V E I N D E X /S P H E R I C A L & A S T I G M AT I C E F F E C T

A lens is created using specific correction values matched

against an apex refractive index, and must be within tolerant

levels. Should it pass the minimum requirements, it will be

designated as Class 1, which is suitable for occasional wear and

has a refractive power of ± 0.06 dioptres. This is the normal

optical quality for all safety spectacles & goggles.

M AT E R I A L & S U R FAC E Q UA L I T Y

The surface of the lens is inspected for any defects that might

affect the vision of the wearer. These defects can include

scratches, bubbles, inclusions or cloudiness.

T H E C E C E RT I F I C AT E

After successful completion of the rigorous testing procedures,

the glasses will be awarded a CE certificate and approved for

use as safety glasses. Each model will have its own tests carried

out and its own certificate issued.

IF A SAFETY FRAME OR LENS IS CE MARKED IT WILL CARRY ITS OWN MARKINGS TO PROVIDE THIS INFORMATION TO THE WEARER. THE MARKINGS WILL BE ON BOTH THE LENSES AND THE FRAME.

ADDITIONAL TESTS THAT MAY BE CARRIED OUT

F L A M M A B I L I T Y

Safety glasses must withstand a steel rod which is heated to

+650 degrees. The rod is then placed on the glasses or lens for

5 seconds and is considered viable if it does not ignite or glow.

R E S I S TA N C E TO I N C R E A S E D T E M P E R AT U R E /AG I N G

The glasses are placed in a furnace or heating cabinet at

temperatures in excess of 55 degrees for 60 minutes. At the

end of this period they are inspected for deformation, aging

and optical changes.

C O R R O S I O N R E S I S TA N C EThe glasses or goggles are placed into boiling sodium chloride

solution for at least 15 min. The frame is removed and placed

into sodium chloride at room temperature for an additional 15

min before being removed, rinsed and inspected.

If all surfaces of the metal parts are corrosion free, the frame

will have been deemed to have passed.

R E S I S TA N C E TO AG I N GBY U V E X P O S U R E

The lens to be inspected is exposed to 50 hours of strong

radiation from a UV lamp. This will provide reassurance that

the frames and lenses can withstand UV exposure in simulated

sunlight for 2 years. The inspector will be measuring whether

transmission and stray light meet the specific requirements.

F I E L D O F V I S I O N

All glasses and goggles must have a sufficient field of vision for

the wearer. This test is carried out via a laser in a fixed head

position which simulates fixed viewing directions. The glasses

or goggles will only be deemed certified if the minimum field of

vision is observed.

S I D E P R OT E C T I O N / S I D E S H I E L D S

This test is similar to the field of vision test and ensures that the

field of vision is not obstructed by any side protection that is

included on the frames. It also requests that the side shields

are fit for purpose and restrict foreign objects from going into

the eye or frame from the side.

A D D I T I O N A L T E S T P R O C E D U R E : R E S I S TA N C E TO DA M AG E F R O M S M A L L PA RT I C L E SIn this procedure, a sand trickle test in used where 3kg of natural quartz sand is sieved onto the lens. The lens is then checked

using the Scattered Light test to ensure its clarity after exposure to small particles.
