Wearing dirty glasses is annoying, as well as being harmful to the eyes. Perhaps for this reason, as soon as we notice that they have gotten dirty, we tend to quickly take them off, bringing them close to our mouths until the lenses cloud up with our breath, and then rub them with the shirt or garment we are wearing. A custom that, however, is discouraged by experts. Let’s see how to clean glasses correctly.
It is important to maintain a rigorous cleaning of the lenses, since this way we will avoid losing sharpness and even scratching, which can damage our eyesight. Today, most lenses have special hardening, anti-fog or anti-scratch treatments, so the user must pay attention to maintenance so as not to damage the layers.
All the experts agree in pointing out which is the best method to clean glasses, which is also the simplest and most effective:
During the washing process it is important to hold the glasses with your hand from the central part, not from the temples, to avoid deformation and breakage.
Therefore, paper clothes or napkins should not be used, as these materials can cause scratches and even remove the anti-fog layer. In the same way, you should not use any pointed object to try to remove encrusted dirt; It is better to repeat the five steps detailed above as many times as necessary and avoid the use of solvents and alcohol.
Dry cleaning is also not recommended, as there is a risk of scratching the crystals. If the glasses get dirty in a place where we do not have access to water, we must use optical spray cleaners or cleaning wipes, always drying with a chamois or microfiber cloth.
A piece of advice: at home, always wash your glasses under the tap and keep the cleaning liquid that they gave us at the optician’s (or that we bought at the supermarket) in the bag or jacket to use when we’re out on the street.
From the National College of Opticians and Optometrists they offer other recommendations to take care of glasses:
And remember that the best way to keep the lenses in good condition is to always store the glasses in their protective case. Leaving the glasses parked in any place when they are not used or hanging them from the collar of the shirt or as a headband on the head will only dirty and deform them.
