Which element in eyewear maintenance helps prevent scratches on lenses?

Using lens cleaning solutions and microfiber cloths is the most effective element in eyewear maintenance for preventing scratches on lenses. Microfiber cloths are specifically designed to be gentle on lens surfaces while effectively removing dust, dirt, and smudges without causing friction or abrasivity, which can lead to scratches.

Lens cleaning solutions complement this by providing adequate lubrication during the cleaning process, allowing particles to be lifted away without scratching the surface. This combination of a soft, non-abrasive cloth and a suitable cleaning solution ensures a thorough clean while protecting the integrity of the lens.

In contrast, options such as paper towels, water and soap, and rough fabrics can potentially damage the lenses. For instance, paper towels and rough fabrics may contain fibers that are abrasive or can scratch the lens coating during cleaning. Water and soap are not always effective in ensuring a streak-free clean and might not address all types of residues effectively.
