4.2. Purpose

The Riester ophthalmoscopes described in these instructions for use were produced
for examination of the eye and fundus.
CAUTION!
Because prolonged intense exposure to light can damage the retina, the use of the
eye exam device should not be unnecessarily prolonged, and the brightness setting
should not be set higher than needed for a clear representation of the target struc-
tures.
The irradiation dose of the photochemical exposure to the retina is the product of ir-
radiance and duration of irradiation. If the irradiance is reduced by half, the irradiation
time may be twice as long to reach the maximum limit.
Although no acute optical radiation hazards have been identified for direct or indirect
ophthalmoscopes, it is recommended that the intensity of light directed into the pa-
tient's eye be reduced to the minimum required for examination/diagnosis. Infants/
children, aphasics and people with eye diseases are at a higher risk. The risk may be
750 mA mean life span 15 h
52 mA mean life span 20.000 h
