Lens cleaners are specialized solutions designed to clean optical surfaces, such as glasses, camera lenses, and smartphone screens. They effectively remove dirt, smudges, and fingerprints without damaging the lens coatings. Most lens cleaners come in spray bottles or pre-moistened wipes for convenience. These cleaners typically contain a mixture of water, alcohol, and gentle surfactants. It's important to use a microfiber cloth when applying the cleaner, as this material is soft and reduces the risk of scratching the lens. Regular cleaning helps maintain clear vision and prolongs the life of optical devices.
