NON-VARIABLE VECTOGRAM

Equipment: Tranaglyph slide (non-moving), e.g. Bernell 50 series, holder, red/green glass and legs (optional)

Purpose: To develop depth perception, and fusion flexibility

Procedure: Set up is the same as above. The patient shifts from section to section on the card. The demand increases the further apart the two colors are on the card. Determine what skill is being stimulated just as above: colors same side: convergence, colors opposite side: divergence. The amount of vergence stimulated is described in prism diopters, which is a number followed by a triangle on the card.

Gradations: Same as for variable, except for pulling cards
apart.
