Is it something to worry about

I’m 8W5D and today while i was at work i felt as if i couldn’t see. Iv never had this happen before it was very weird, idk how to explain it, it felt like i had looked at the sun, like a huge glare blocking my eyes from focusing. It lasted around 20mins & now I’m fine just have a slight headache . But i was kinda freaking out. Anybody had that happen to them? 😖
