Could Multifocal Glasses started mine

I have suffered awful headaches for majority of my life. Went to doctors, headache specialists. They died out when I got into my late 40’s. Had some odd ones, the sunday headache which slowly over time every sunday got worse and gave me awful nausa. The zig zag lines started minus headache when I was 50. Ended up rushing to ER at eye hospital and was told occular Migraine. They vanished for a year. Came back for a year, vanished again. Now they have reappeared this year and currently two a week. Always seems to be triggered by light dark contrast.

Got me thinking the time they started was when I switched to Multifocal glasses. Trying to find a cause. They are so scary even though they follow the same pattern and only last 20 mins.
