Most people who use glasses every day know to not simply use only a microfiber cloth to clean their glasses. Yet many still use their shirttail, or maybe water or a paper towel to help clean them. Here are some reasons why you should stop doing that.
If you do not use a spray, it causes friction
By far one of the biggest reasons of scratched glasses is “cleaning.” Yes, a simple swipe of your shirttail will eventually destroy your precious lenses. You may not notice it at all for a while but eventually all those little scratches end up being a big deal. First, for those of you using your shirt tail to wipe off a lens, stop now. Not only does dirt become embedded in clothing rather quickly, but also fabric softener can leave a film, and some materials just plain are not nice to plastic, and will leave sure scratches. Even using paper towels, or even toilet paper and Kleenex can also put fine scratches in a lens. You will not notice it at first, but after a year or two, many fine scratches will become evident and you will have to end up investing in a new pair.
Using the spray provides a better cleaning
A big no-no for glasses users is to never ever clean your glasses dry, no matter what type of material you may be using. Liquids act as a barrier or a lubricant, which helps reduce the friction between the cloth and your glasses, and ends up delaying the risk of scratching. Using the spray that your lens retailer provides is your best bet at reducing any further damage to your glasses.
The spray is made especially for glasses, do not use water.
The spray that they cell at your lens retailer is a spray that is specifically made for cleaning lenses. It performs a chemical cleaning and it has detergents in it that do not damage your lens layers. It is said that it is better to use the spray regularly: 2-3 times a week, but not daily. Because at an excessively use, even these specific detergents can damage the lenses coatings. It is better using the spray regularly 2-3 times a week, but not daily.

Some sprays contain special substances that enhance their protection, after using them:
• Anti-fog – for fog free lenses
• Oleophobic – fats and oils are easier to clean and does not adhere to the lens
• Hydrophobic – water does not stay on the lens, drain quickly
