COMMON QUESTIONS ABOUT EYE PROTECTION 
 
1.  “O.D.” is marked on the laser eyewear.  What does it mean? 
 
O.D. stands for optical density.  It is specific to the spectral wavelength 
marked on the eyewear and represents the capability of the eyewear to block 
out laser light.  The higher the O.D., the greater the amount of light blocked 
out.  The O.D. marked on the eyewear is sufficient to provide protection for 
the use described in the associated product insert. 
Eyewear is not interchangeable for different wavelengths.  Eyewear 
designated for use at 532 nm should only be used when viewing the 532 nm 
wavelength.  For more information about the O.D. of Laserscope’s eyewear, 
consult the product insert shipped with the specific eyewear. 
 
2.  Why is the eyewear for the GreenLight HPS
 laser system 532 nm 
laser tinted? 
 
The human eye is very sensitive to light in the green portion of the spectrum.  
Since the GreenLight HPS
 532 nm laser system operates in the visible green 
light wavelength, protective eyewear for 532 nm must block a portion of this 
green light to provide adequate eye protection.  
 
3.  Does my eyewear protect me if I can see green light during 
lasing? 
 
Laserscope eyewear is designed to block out a specific portion of the light 
spectrum in green, and allow other parts of the spectrum to pass through.  
There is nothing dangerous about viewing green light at low intensity or the 
red aiming beam.  The eyewear is designed to protect against the high 
intensity of the green laser light used to perform surgery. 
 
4.  Why do goggles fog and what can be done to prevent this from 
happening? 
 
The fogging of goggles is a common problem experienced by many laser 
users.  The warmth of the wearer, stress of the case, and coolness of the 
procedure room are ideal conditions for condensation to form on all eyewear, 
despite manufacturing design.  The use of anti-fogging agents after cleaning 
and before each case should reduce the fogging problem. 
 
5.  What is the potential for a fiber to break during a procedure and 
cause eye injury? 
 
During normal use, a fiber may incur stress when it is inserted into the 
cystoscope.  Stress is a concern when fibers are being used because small 
nicks in the nylon jacket of the fiber can result in increased fragility.
