diplopia or double vision - more seen in adults (maturity / plasticity of neural pathways) and suppression mechanisms of the brain in sorting out the images from the two eyes. cyclotropia, a cyclotorsional deviation of the eyes (rotation around the visual axis), particularly when the root cause is an oblique muscle paresis causing the hypertropia.
An oblique prism is a prism in which the joining edges and faces are not perpendicular to the base faces. Example: a parallelepiped is an oblique prism whose base is a parallelogram, or equivalently a polyhedron with six parallelogram faces. Right Prism. A right prism is a prism in which the joining edges and faces are perpendicular to the base ...
An Amici roof prism, named for its inventor, the Italian astronomer Giovanni Battista Amici, is a type of reflecting prism used to deviate a beam of light by 90° while simultaneously inverting the image. It is commonly used in the eyepieces of telescopes as an image erecting system. It is sometimes called an Amici prism or right angle roof ...

Most (50–60%) of the drag on an artillery shell derives from the nose portion of the shell. Artillery shells travel through the air at supersonic speeds; as the shell pushes the air out of its way, it creates shock waves that bleed off the shell's kinetic energy and therefore reduce its airspeed.
Porro prisms are most often used in pairs, forming a double Porro prism. A second prism rotated 90° with respect to the first, is placed such that light will traverse both prisms. The net effect of the prism system is a beam parallel to but displaced from its original direction, with the image rotated 180°.
Littrow (optical) prisms typically have the shape of a (geometric) prism with a 30°/60°/90° right triangular base, [1] [2] equivalent to half an equilateral triangle. Typically, they are coated with a reflective film coating on the surface opposite the 60° angle. This design was devised by Otto von Littrow (1843—1864). [3]
