Heterophoria is a medical term used to describe a condition where the eyes are misaligned when they are at rest. This often results in double vision, headaches, blurred vision, and eye strain. There are several synonyms for heterophoria that can help describe this condition, such as oculomotor imbalance, eye muscle weakness, ocular misalignment, and imbalance of ocular alignment. While the symptoms of heterophoria can be uncomfortable and frustrating, there are treatment options available, such as prism lenses, vision therapy, and surgery, that can help correct the misalignment and improve visual function. If you experience any symptoms related to heterophoria, it is important to seek the advice of a qualified optometrist or ophthalmologist.
