The invention provides an eyeglass-like apparatus and methods that may be used similarly to treat existing postural issues especially FHP and to prevent them in unaffected people. The apparatus may comprise a means for creating an obstruction in a zone within the field of vision of a person which size and position can be adjusted. The obstruction can be mounted in or on a lens, or a pair of lenses, or to a wearable frame without any lenses, or with non-vision-corrective translucent or transparent panes instead of lenses, or may be a small nose-mounted fixture, or may comprise a solid material, an electronic panel, or may be integrated as a component aspect of the shape and manufacture of a lens itself, or may be permanently fixed element in the lens, such as an etching, or it may be removable.
