Why does my left eye keep twitching sometimes?

Q: The top left corner of my left eye keeps shaking sometimes. I don't know whether it’s shaking due to some internal problem? Even if I hold my eye and close it with one hand, I can feel the shakiness on my hand. It goes off after sometime. But it happens very often. What is the reason for this?

A:The person may be having myopia. This is an involuntary firing from the nerve, which causes muscle fascicules to twitch. A course of multivitamins with B-complex will help resolve the problem.
