Its not my only cause, I can struggle with some screens regardless. But if I were to eat cooking oil, the lcd screen I am using fine now becomes unusable. Similar thing happens if I eat anything with curcumin, or silicon dioxide added (stops salt clumping together, also used in pills). I don't know why, but its been happening for about 4 years now. I have a lot of food intolerances and mild allergies, with new ones appearing fairly regularly. Whilst I don't get a rash or any other symptoms from cooking oil, I assume I am slightly allergic to it, and its getting into my brain and causing some inflammation because of that allergy. Every so often a new food trigger appears.
The first food trigger to affect my tolerance of screens was sunflower oil. I ate a lot of crisps (lots of sunflower oil) one day and was in much more pain the next day. Stopped eating crisps, got a lot better, soon figured it out was the sunflower oil. Since then its slowly expanded to be all cooking oils, and the other things I mentioned.
