Visual Influences on Vestibular Adaptation

The goal of this study is to learn whether a balance-training exercise called incremental vestibulo-ocular reflex adaptation (IVA) is safe and effective for adults with vision impairments, with or without additional vestibular (inner-ear balance) problems. The main questions it aims to answer are: * Does IVA cause only mild, temporary symptoms and no serious adverse events? * Does IVA improve eye-movement reflexes, balance, and walking, and do these improvements differ between people with vision problems alone and those with both vision and vestibular impairments? Researchers will compare adults with vision impairment only to adults who have both vision and vestibular impairments to see whether the groups respond differently to IVA. Participants will: * Complete symptom ratings before and after IVA * Undergo tests of vestibular reflexes (e.g., VOR gain) * Complete balance and walking assessments
