Phorias Test:
The phorias test measures parallelism of the ocular axes at physiological rest.
All phorias (heterophoria) translate as visual fatigue (asthenopia), notably in intense
conditions (screen work).
In time, a heterophoria, along with fatigue, can become diplopia (double vision). This
test is particularly interesting for screening latent heterophorias.
