What is the main benefit of using anti-reflective coating on lenses?

The primary advantage of applying an anti-reflective coating to lenses is the reduction of glare and reflections. This coating allows more light to pass through the lens, enhancing visual clarity and comfort, particularly in challenging lighting conditions such as bright sunlight or when using screens. By minimizing reflections on the lens surface, anti-reflective coatings help to eliminate distractions for both the wearer and others, leading to a more pleasing aesthetic appearance.

Moreover, by reducing glare, these coatings can significantly enhance the quality of vision, making them especially beneficial for activities like driving at night, working in front of digital screens, or any other situation where light can create visual disturbances. The other options, while they may offer some benefits, do not capture the fundamental purpose and effectiveness of anti-reflective coatings as thoroughly as the reduction of glare and reflections does.
