Safety Eyewear:
Two sets of laser safety goggles (part #: TLC-
901
) are supplied by Theralase™ as standard accessories. These laser safety
goggles are provided for viewing of diffused laser light only and are not indicated for direct viewing of the laser output.
It is highly recommended that both the practitioner and the patient wear laser safety eyewear during laser therapy treatment.

Optical Density (“O.D.”) is the scientific term to describe a material’s ability to block light of a certain wavelength. It is a
logarithmic formula, where the higher the O.D. value, the better the material blocks light. For example, an O.D. of 1 means
the material will allow 10% of the light penetrate the eyewear at a particular wavelength.
