In terms of vision screenings, why is the phoria test important?

The phoria test is crucial for assessing eye alignment because it identifies latent misalignments of the eyes that can affect a person's vision and overall visual comfort. Phorias refer to situations where the eyes are not properly aligned when both eyes are open but may be aligned when one eye is covered or closed. This test helps to uncover issues that may not be readily apparent during other vision tests, where the eyes are working together. Detecting and understanding these misalignments is essential for developing appropriate treatment options, such as vision therapy or corrective lenses. Eye alignment is a key factor in ensuring that both eyes work together efficiently to create a single, clear image, which is vital for depth perception and overall visual function.
