A positive aspect of anti-reflection coated lenses is:

Anti-reflection (AR) coated lenses are designed to minimize reflections that can occur on the surface of the lenses. When it comes to the aspect of thick lenses appearing thinner, this is due to the way AR coatings work. By reducing glare and reflections from the front and back surfaces of the lens, the lenses allow more light to pass through and reach the eyes. This transparency gives the lenses a clearer and more "invisible" appearance, making them seem sleeker and less bulky, which can be particularly beneficial for higher prescription lenses that tend to be thicker. This optical clarity can create an enhanced aesthetic appeal, as wearers may prefer the look of thinner lenses without distracting reflections, leading to a more streamlined and elegant optical solution.
