Question: 1 / 400

What is the purpose of anti-reflective coating on lenses?

It reduces glare from light sources and improves vision clarity

The purpose of anti-reflective coating on lenses is primarily to reduce glare from light sources and enhance vision clarity. This coating minimizes reflections that can occur when light hits the surface of the lenses, which is especially useful when driving at night or working on a computer. By allowing more light to pass through the lenses rather than reflecting off them, this coating improves the overall quality of vision and can make visual tasks much more comfortable and efficient.

While other options mention attributes like scratch resistance, color changes, or thickness, these do not pertain to the primary function of anti-reflective coatings. The main focus of this technology is indeed glare reduction and clarity improvement, making it a significant feature for many lens wearers.
