My left eye goes a bit shakey when I glare at things with my head tilted back... should I be worried?

Question

My eyes are perfectly normal when I'm looking at things as usual.

But like when I tilt my head back and open my eyes wide out open, my left eye shakes up and down a lil! Like 1mm.. is this something of concern or serious disease? It only started happening 2 days ago and it ONLY happens when I tilt my head back a bit and concentrate/squint/glare with my left eye.

I'm really scared!!! I don't want to go blind.

Answer 1

It is probably just a muscle twitching from doing somethin gyou are not used to doing. I am relaly not all that convinced that you are going blind at all.
