Can computer screen cause allergie

Patient: Can Computer Screen cause allergy? I have chronic sinusitis but even if i did some skin and blood exams i cant find thesource of my allergy. I stay a lot of time in front of a computer for work and also in my free time so it was natural to think of this question. What are the best exams to find the source of my allergy?

Symptoms: Sinuses inflamed and swollen
