Selective visual field restriction or stimulation during ocular movement is a challenging task that holds promise for basic research and for simulating, measuring, monitoring, and treating psychological, neurological, and ophthalmological conditions. This invention discloses an optical apparatus and method that can restrict visual information from reaching selected areas of one or both retina of a human user during free ocular scanning, using a combination of (1) polarized contact lenses that have at least two areas that each linearly polarize light in planes orthogonal to one another, (2) spectacle lenses that linearly polarize light uniformly across the lenses, and (3) spectacle frames that allow said spectacle lenses to rotate. Depending upon the rotational degree difference between the planes of polarization between the spectacle lenses and each area of the contact lenses, light can be restricted from reaching certain areas of the retina of one or both eyes of a human user.
