KEEP THEM CLEAN

DOs

• To clean your lenses use a special lens spray provided by your eye care professional or warm, soapy water.
  
• Always wipe your lenses dry immediately.  
  
• Remember to occasionally wash the lens cloth, as a dirty cloth may have accumulated particles that could scratch lenses.  
  
• Clean the lenses immediately if liquids such as detergent, cosmetics, oils, sweat, juices get on them. Stains may be difficult to remove and even damage the coating on the surface if not cleaned immediately.  

DON'Ts

• Don't wipe lenses with a tissue, paper towel, clothing, rags or paper napkin. They can have a rough surface.  
  
• Don't wipe lenses when they’re dry. Any debris on their surface or dust in the cleaning cloth could cause scratches. 
  
• If wiping lenses when dry is necessary, use a lens cloth. Do not wipe with too much pressure as it may scratch and damage the lenses.  
• Don't spit on your lens. While spit is a handy cleaning solution, saliva may contain oil or something else that’s damaging. 
  
• Exhaling on lenses before cleaning doesn’t get them very wet, and is not recommended.  
  
• Do not clean lenses with hot or boiling water.  
  
• Do not clean lenses with harsh soaps, household detergents or glass cleaners. Never expose lenses to harsh chemicals such as hairspray, lacquer, alkalis or acids, etc. Don't use ammonia, bleach, vinegar, or window cleaner, which can harm lenses and their coatings.  
  
• Leaving the lenses in a cleaning solution too long will damage the lenses and coating.  
  

KEEP THEM PROTECTED

• Do use a hard-shell case that is the right size for your glasses.  
  
• Do lay glasses down with their lenses facing upward.  
  
• Do use both hands to put glasses on and take them off, and keep glasses on your nose, not on your head. Otherwise, frames can become misaligned. Even clean lenses are less than effective if they aren’t positioned properly in front of the eyes. 
  
• Don't put unprotected glasses in a purse, pocket, or bag.  
  
• Don't regularly place glasses on a sink or vanity top. Spatter, sprays, and cosmetics can soil lenses, and hair spray or perfume can damage anti-reflective coating.  
  
• Don’t leave glasses in a hot car. Especially avoid the dashboard. The windshield will act like a magnifying lens. 
  
• Remove your glasses before going in a sauna . 
  
• Other examples of potential heat damage include: Opening an oven, BBQ or wood stove, placing them on top of a radiator, exposure to direct and prolonged heat from a blow-dryer, etc.
