ALCOHOL TO DISINFECT YOUR SUNGLASSES?
These days, we feel that all the care is little. We disinfect everything with alcoholic solutions and even use 70% ethyl alcohol to make sure we protect ourselves properly. If you have ever cleaned your sunglasses with alcohol, stop doing so immediately! Alcohol is corrosive to the materials that make up glasses.
Ethyl alcohol is able to corrode the finishes of metal frames, paint, chrome on the frame or the hinges on the rods. On the acetate frames, it can damage the material leaving it matt and brittle.
As far as the lenses are concerned, if alcohol is used it can, for example, destroy the polarizing filters. This causes the lens to "peel". If the lenses are made of polycarbonate, they will become progressively more parched and sooner or later they will break.
In short: No ethyl alcohol in your sunglasses!
You can and should clean your glasses regularly. Nothing better for that than water and soap. First of all, the health authorities maintain from the first minute that soap and water are the two elements that work best in disinfecting and cleaning our hands and objects such as sunglasses. Second, because there is no risk of water and soap corroding the materials.
Soaping the goggles with kitchen detergent, going through clean running water and drying with the help of a microfibre cloth, is effective and simple. If you want to know in more detail the correct process to clean your glasses click here.
