Why is my my vision partially blocked by headaches sometimes?

[Malta]

Each time when I get headaches,my vision will be partially loss. Why does this happen?

It is one of a sign of migraine, usually you will suffer headache first, then your vision will loss temporarily. Go to your eye doctor to diagnose as soon as possible to see if my deduction is correct.

Maybe you are suffering migraine which can also affect your vision.When it happens,you can hardly see things,But it won't damage your vision.

If you get headache first,then accompanied by loss of vision,it possibly can be migraine.You'd better go to see your doctor.
