Hey mny dad is 61 and he has has this problem that he sometimes have darkness in front of his eyes and headache as well, most of the time it is because of a bad stomach... what would you suggest... why is this happening..

What other medical problems does your dad have ? I don't see how having a bad stomach could give him headaches and blurred vision. There has to be something else going on as well. What type of medications is he on ?

Sounds like he needs an eye exam and a new pair of glasses. The eye exam may detect a cataract developing or glaucoma or any number of issues.

Having eye trouble could cause headaches, possibly, but stomach trouble seems unrelated... he should see a GP after he has his eyes checked.

I'm not a professional... just my opinion from life experience.

Have a great day,
