At the most basic level, all AR coatings defuse light reflections on the front and back surface of the lens. The coatings allow more light to pass through and improve your visual acuity.

With an AR coating, light hitting the front surface of the lens can pass through instead of bouncing off. Having the back of the lens coated prevents light that’s shining behind you from bouncing off the back of the lens and back into your eye. Having a dual surface coating provides crisp, clear vision in all light conditions.
