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
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
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

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
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.
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
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
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.
