For a few weeks Ive noticed my eyes aren't aligned shall i go to the doctor or optician?

I think it's worth a visit to the opticians, just to be on the safe side. You might need glasses with prisms that will realign the light in your eye and will realign them. Go and have an eye test and see what they say. Our eyes are always changing with age so problems can arise at any age. But go to a good optician, I went to the same one since I was 7, and it turns out the reason I couldn't draw a straightt line was because I needed prisms, something only pointed out when I went to Specsavers!
