What is a characteristic feature of lens care recommended by current best practices?

Utilizing microfiber cloths is considered a characteristic feature of lens care recommended by current best practices. Microfiber cloths are designed to effectively clean lenses without scratching the surface, which can be a risk with other materials. They have fine fibers that capture dust, oils, and smudges more efficiently than traditional materials. Their softness ensures that the lenses remain undamaged, which is crucial for maintaining optical clarity and extending the life of the lenses.

In contrast, using glass cleaners or employing harsh chemicals can potentially damage lens coatings or leave residues that impair vision. Rubbing with rough fabrics poses a risk of scratching the surface of the lenses, leading to diminished visual quality and necessitating repairs or replacements. Hence, the use of microfiber cloths aligns with the best practices in lens care for preserving both the integrity and clarity of optical lenses.
