I am Dr Mbong. Blurred/obstructed vision even of one eye from any cause (including a cataract
), overtime can cause problems with balance and dizzyness
However the balance issues and dizziness
can be due to other causes and medication you may be taking.
So you will need to see a physician and complain so as to get examined and screened for other possible causes. That will be a good thing to do, so that underlying illnesses are discovered on time.
