When I try to focus on something , either close or faraway, my head shakes a little bit. There is a sensation in the back of my head, it's really uncomfortable. I can't focus without moving my head a little bit thus.
I wear spectacles, and my eye power is 3.5 left, and 4 right (hyperopia / farsighted). I really don't know what's the problem, but I'm pretty sure it's related to my eyes.
Can someone please guide? (I don't know which group to put this under)
