Headache with eye floaters ( first time)

Yesterday I had pain in my right forehead and on my left  eyes I felt like eye floaters kind of design on left eye I got scared and I just close my eyes and took rest for 10 minutes, eye  floaters was gone but headache was there. After 1 hour of sleep headache got reduced. Note: *I have myopia  but I m not wearing specs. *I got this headache when I was watching too much of mobile from morning to afternoon after that I got it *Normally during winter seasons I used to get head weight for heaviness *Before 1 month I had gallbladder operation so I was given general anaesthesia *Since I am sending my daughters to school I used to get 7 hours of sleep per day *I have tmj dysfn on left side jaw * Is it normal or did I stress my eyes too much because of mobiles
