Why do I get a migraine and see halos when looking at bright lights?Eye & LASIK Neurology
My bf has been having migraines, and seeing halos and spots when looking at bright lights. This has been going on for 2 years.
These can include bright or flickering lights. Other reported triggers are disturbances in sleep patterns, certain types of food, and alcohol.
It is possible that the 'halos and spots' experienced are the 'aura' experienced before the headache starts. These are often described as zig zag bright lights that last for 15-20 minutes, associated with blind spots in part of the vision that also last for that period of time. After that, the lights and blind spots disappear by themselves.
The best thing for a person with migraine are to avoid the known triggers where possible, and then if a person feels that an attack is starting, certain medications can help to 'break' the attack or relieve the headache. Other things that help are having a nap in a dark, quiet room.
Of course, there are also other possible causes of headaches and visual disturbances, so if the attacks are particularly disturbing or getting worse, do consult with a doctor to firstly, make sure there is no other cause of the headache, and secondly get some effective treatment for it.
