How do you treat visual disturbance?

​

Firstly, do not panic; visual disturbances can be frightening, but in most cases are short lived. If you are driving or operating machinery, stop what you are doing and wait for the symptoms to go away. Make a note of your symptoms, how long they lasted and what you were doing just before they began. In most cases, there is a common trigger and keeping a diary of symptoms can help work out what the trigger is. Simply avoiding the trigger, where possible, may be all you need to do.

Always seek advice.
