This occurs because the phase accumulated in the layer relative to the phase of the light immediately reflected decreases as the angle increases from normal. This is counterintuitive, since the ray experiences a larger total phase shift in the layer than for normal incidence. The web effect is that the relative phase is in fact reduced, shifting the coating, such that the anti-reflection band of the coating will proceed to shorter wavelengths as the optic is tilted. Non-normal incidence angles also usually cause the reflection to be polarization-dependent.

• Always wet or moisten your lenses as well, using a dry cloth on dry lenses may cause dust or other debris to scratch your lens.
• The easiest interference anti-reflective coating consists of a single thin layer of transparent material with refractive index equal to the square base of the substrate’s refractive index.
• therefore the lenses are quicker and better to clean.
• However, the anti-reflective coating might help decelerate this decline – and therefore your eyesight is more prone to stay the same and not worsen.
• With an AR coating, light hitting leading surface of the lens can go through rather than bouncing off.
