Safety Information
If the value of radiance was 40 [mW/cm2/sr], 6 minutes would be needed to reach the rec-
ommended limit.
That is, the retinal exposure dose for a photochemical hazard is a product of the radiance
and the exposure time.
Since La and Lb of this instrument are extremely low, the risk of the photochemical hazard is
also very low. While no acute optical radiation hazards have been identified for this instru-
ment, it is recommended that the intensity of light directed into the examinee's eye be limited
to the minimum level which is necessary for diagnosis. Infants, aphakes and persons with
diseased eyes will be at greater risk. The risk may also be increased if the person being
examined has had any exposure with the same instrument or any other ophthalmic instru-
ment using a visible light source during the previous 24h. This will apply particularly if the eye
has been exposed to retinal photography.
