Without going into great detail, polarization works by filtering out horizontal glare — that is, light reflecting off of water, fallen snow, car hoods, etc.  The substantial reduction in glare they can achieve helps explain why polarized eyewear is a favorite among skiers, fishermen, and professional drivers. The effect is achieved by applying a thin coating to each surface of the lens. This coating is susceptible to scratching or dissolving without proper care. Although there are budget-friendly polarized glasses out there, odds are good that you spent a decent chunk of change on your pair.  So always follow the manufacturer’s instructions for proper care, along with these tips:  Always keep your glasses in the provided protective case when not in use. This is one of the easiest ways to prevent scratches and the accumulation of dust and dirt. Don’t leave your glasses exposed to extreme temperatures, which can deform the polarized coating.  Avoid, for example, leaving the glasses under the front windshield, where they can bake under the blazing sun.  Never “dry rub” your polarized lenses, even with a clean microfiber cloth.  The friction caused by even tiny bits of dust or debris can cause damage if not lubricated with water or an approved cleaner. You may receive a cleaning and repair kit with your polarized glasses.  Use these as recommended for regular cleanings and minor repairs.  However, going back to the retailer or another eyewear store that will do cleanings, inspections, and repairs can really pay off. High quality polarized lenses can be quite expensive, and it is likely worth your investment to have occasional professional care done on them.  Go in when something is obviously wrong or the glasses are too caked with oils, residue, etc. for you to clean yourself.  Also consider going in for check-ups once or twice a year as well.
