Although the Optovera test is simple and automated, following a few key recommendations helps avoid errors and ensures that each measurement is valid and comparable to the worker’s baseline.
Before the test
-
Remove face items: helmets, glasses, protectors, or any accessory that interferes with the visor.
-
Check the device: make sure the battery is charged, and the visor is clean and unobstructed.
-
Proper location: perform the test in a quiet space with no distractions.
During the test
-
Proper visor placement: make sure it fits securely and blocks external light.
-
Stay still: do not move your head or the device during the measurement.
-
Look straight ahead: fix your gaze on a single point.
-
Eyes wide open: open eyelids fully.
-
Don’t blink: avoid blinking during the 4 seconds of light exposure.
After the test
-
Wait for the on-screen result: Fit / Unfit.
-
If the result is “Unfit”: repeat the test after a few minutes to confirm.
-
Verify synchronization: if connected to the internet, results will upload automatically.
Additional tips
-
Workers wearing contact lenses do not need to remove them.
-
In bright sunlight, make sure the testing area is shaded to avoid light leaks when removing the visor.
-
HSE supervisors should provide a hands-on demonstration during training to minimize routine errors.
Conclusion
By following these recommendations, HSE teams can ensure that Optovera tests produce reliable results, avoiding unnecessary repetitions and minimizing operational disruption.
