Backside AR (Anti-Reflective) Coating is a thin, clear treatment applied only to the inner surface of a spectacle lens (the side facing the eye). This coating eliminates reflections that bounce off the back of the lens and into the wearer's eyes.

Light entering from behind the wearer (such as car headlights or overhead office lighting) hits the back of the lens and reflects into the eye. This coating eliminates that internal glare.
This coating is highly beneficial for drivers, especially during night driving, as it stops the glare from oncoming headlights from reflecting into the eye. It is also needed for computer users who deal with reflections from overhead lights.
By eliminating glare, the backside AR coating improves visual comfort and clarity. It prevents the internal reflections that cause eye strain and fatigue, making the vision field cleaner and sharper, especially in low light.
The backside coating is arguably most critical for night driving comfort. It stops the harsh, concentrated light from headlights hitting the back surface of the lens and reflecting into the pupil, which can cause momentary visual disorientation.
No, a complete AR treatment is usually applied to both the front and back surfaces of the lens for maximum glare reduction.
No, AR coating is applied by the lab using a high-tech vacuum deposition process.
No, AR coating reduces visible light reflections. UV protection is a separate feature built into the lens material.
Backside AR coating is a medical recommendation for sunglasses to prevent "bounce-back" glare from entering your eye from behind. If you suffer from light sensitivity or migraines, ensuring your lenses have vacuum-deposited AR can reduce visual triggers.
