This educational presentation is provided for a better understanding of the concepts behind the main lens types, and their value toward enhancing your vision.

Progressive lenses combine near, intermediate, and far distance correction into one lens. They are available as standard, advanced, and premium. All have a similar distance lens area, but their intermediate and near lens sizes vary. All are blended with no visible lines.

Standard progressive lenses have a wide distance lens above. They have a narrow intermediate distance lens in the middle. Their reading lens below is somewhat narrow. This type has notable side distortion below.

Premium progressive lenses have a wide distance lens above. They have a much wider intermediate distance lens in the middle. Their close reading lens below is very wide. The premium type has the least side distortion. As such, they provide the most visual comfort and ease of adjustment.

Anti-Reflective, or AR coating, added to your eyewear lenses can have multiple benefits.

AR coating can reduce reflections on your lenses. This makes your eyes more visible to those around you. AR coating can make a stronger prescription lens appear thinner. Inner lens reflections are also reduced.

AR coating comfortably reduces lens reflections from room and window lighting. It can reduce glare from computer screens and office lights. Outdoors, the coating reduces reflections from your eye and lids back onto the lens.

While driving, the coating helps reduce lens reflections from vehicles and windshields. This is also beneficial during low sunlight conditions. At night, halos from headlights can be reduced, improving your ability to see.

So, how does AR coating work? Several thin layers of AR coating are added to the front lens surface. Hot spot reflections are diminished. It is also layered on the back surface of the lens. These layers cancel light waves of back lens reflections.
