To perform the test you will need Bagolini Striated Glasses; Pen torch or a distant light source. Alternatively, trial frames and lenses or a lorgnette can be used. In some cases, the use of prisms is necessary to measure a deviation and test for the presence of binocular functions.
[10] [11] [12] Attention has also been drawn to potential socioeconomic impact resulting from cases of detectable strabismus. A socioeconomic consideration exists as well in the context of decisions regarding strabismus treatment, [10] [11] [12] including efforts to re-establish binocular vision and the possibility of stereopsis recovery.

At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which
Heterophoria is an eye condition in which the directions that the eyes are pointing at rest position, when not performing binocular fusion, are not the same as each other, or, "not straight".
