Lens Cleaning  
Procedure  
Tominimizethepossibilityofdamagingtheopticalcoatingorscratchingexposedlens  
surface, we have developed recommendations for cleaning the lens.  
FIRST, we recommend you try to remove any material from the lens by blowing it off  
with clean, dry deionized air. DO NOT use any liquid to clean the lenses.  
ATorayseeTM cloth is included with the lens kit.  
Proceed as follows :

Always wipe lenses in a single direction. Do not wipe back and for-  
wards across the lens surface as this tends to grind dirt into the coating.  
Do not leave cleaning cloth in either an open room or lab coat pocket,  
as doing so can contaminate the cloth.  
If smears occur when cleaning lenses, replace the cloth. Smears are  
the first indication of a dirty cloth.  
Do not use fabric softener when washing the cleaning cloth or softener  
sheets when drying the cloth.  
Do not use liquid cleaners on the cloth as doing so will contaminate the  
cloth.
