Display light passes through the small central optic which, in combination with the eye’s normal optics, focuses the display light onto the retina. The display light that falls on the outer portion of the contact lens is blocked by the outer filter to prevent it from interfering with the view of the display.
Ambient light from the environment is able to pass through the outer filter. This light enters the pupil and is focused onto the retina. Almost half of all consumers benefit from a lens prescription so this is incorporated into the lens. Light from the environment that passes through the center focusing optic is first defocused and is then blocked by the center filter preventing this defocused light from interfering with the wearer’s normal view of the surroundings.
