1. An apparatus for viewing, comprising:

  • a body having first end portions and second end portions with remaining portions of said body disposed therebetween;

    a first lens connected to said first end portions;

    a second lens connected to said second end portions;

    a first lens cover assembly connected to said first end portions for protecting said first lens, said lens cover assembly including a first polarized lens having a first color;

    a second lens cover assembly connected to said second end portions for protecting said second lens, said second lens cover assembly including a second polarized lens having a second color;

    wherein at least said first polarized lens is rotatable about an axis through a center of said first polarized lens;

    wherein, when said first polarized lens is rotated relative to said second polarized lens in a first direction, the same degree of connection is maintained between said first polarized lens and said first end portions during the time a user is viewing through said first and second polarized lenses and in which a cross-polarization effect is created in which light, that is allowed to pass through said first and second polarized lenses, changes; and

    wherein, when said first polarized lens is rotated in a second direction, opposite said first direction, relative to said second polarized lens, the same degree of connection is maintained between said first polarized lens and said first end portions during the time the user is viewing through said first and second polarized lenses and in which a cross-polarization effect is created in which light, that is allowed to pass through said first and second polarized lenses, changes.
