I Am Having Sudden Insets Of Severe Blurred Vision In

I am having sudden insets of severe blurred vision in left eye. Rest relieves symptoms. Frequently occurs while driving. I cover left eye and stop car till symptom resolves. Opthomologist says atypical migraine based on eye exam. No pain ever associated with episodes. Should I ignore and just deal with it or seek more help. Episodes severe but sporadic for past 2 years. 63 yr of female with he migraines in youth.
