The difference with this laser pointer is the safety factor. Regular laser pointers can cause damage to the retina if they are projected directly into someone's eye. They are graded as safe for public use as they project a visible light that cannot harm the skin. However, care should be taken not to direct the laser into someone's eyes. The GEWA laser pointer is a Class 2 laser with an output of 0.65mW. The output power has been reduced from 1mW to 0.65mW, meaning that the exposure time has been increased 5 times (according to standard EN-60825-1-1994).
The GEWA Laser Pointer has an altered output such that in order to damage the retina, the laser beam must be held absolutely still, fixed on one specific spot, and not moved for approximately 4 seconds which is virtually impossible. This means that the GEWA Laser Pointer has a security time 16 times greater than the regular type of laser pointer used in lectures. This is significant when the person using the laser pointer is wearing it on his or her head and pointing to a communication board or a wall chart. When eye contact is made with a communication partner, the laser pointer may be inadvertently directed into the partner's eyes.
The GEWA
Laser Pointer has been used successfully in hospitals, with
patients in bed who use a communication charts mounted on the
wall. Although these particular patients had a diagnosis of
motor neurone disease (ALS), this application may be relevant
to others.
The laser pointer can be mounted onto caps or glasses frames or a sports head band. Some accessories are supplied with the laser pointer to secure the pointer to these items. A plastic holder can be riveted in position, cable ties, an adhesive plastic holder and Velcro are supplied.
