What is the purpose of an anti-reflective coating on eyeglasses?

The purpose of an anti-reflective coating on eyeglasses is primarily to reduce glare. This coating helps to eliminate reflections that occur on both the front and back surfaces of the lenses, which can be particularly distracting in bright lighting conditions or when using digital screens. By minimizing glare, the anti-reflective coating allows more light to pass through the lenses, resulting in clearer vision and reducing eye strain. This is especially beneficial for individuals who spend significant time working on computers or in environments with harsh lighting.

While other coatings serve different purposes—such as enhancing scratch resistance or modifying tint levels—the anti-reflective coating specifically targets glare and improves visual clarity for the wearer, making it a popular choice for those looking for optimal lens performance.
