Can Eye Problems Cause Lightheadedness?
I read your question carefully and I understand your concern.
The answer is yes, while it is not a typical manifestation of eye issues, it is possible that loss of visual acuity may be associated with some light-headedness. However other more common causes must also be considered, such as anemia, metabolic disturbances, blood pressure fluctuations, heart arrhythmia, neck arthritis etc.
So before suspecting the eyes, some routine blood tests for those issues, blood pressure measurement and EKG are advised to screen for such common causes.
I remain at your disposal for other questions.
