6.1.1 Eye Illumination Safety

WARNING: Illuminators must only be connected to EyeLink CL camera, and

only the supplied cables may be used.

CAUTION: Use of a controls or adjustments or performance of procedures other

than those specified herein may result in hazardous radiation exposure.

CLASS 1 LED DEVICE

IEC 60825-1 (Ed. 1.2:2001)

The EyeLink CL illuminators are compliant with the IEC-60825-1 LED

safety standard as a Class 1 LED device. This standard has been or is in the

process of being adopted by most countries, and regulates many aspects of LED

and laser eye safety, including retinal, corneal and skin safety. Class 1 products

are “safe under reasonably foreseeable conditions of operation, including the

use of optical instruments for intrabeam viewing”.

As these illuminators may be used in situations where they may be viewed

for long periods of time, some precautions should be observed. Our experience

has been that even safe levels of IR illumination can eventually cause some

discomfort due to the slight drying effect of even this low level of illumination.

(This is especially true for wearers of contact lenses). SR Research recommends

that the illuminators not be used for extended periods at distances of less than

150mm (6 inches) from the eyes. This will ensure an exposure of less than 1.2

mW/cm² (milliwatts per square centimeter). Exposure decreases as the square

of the distance, so even slightly larger distances will reduce exposure

significantly.
