I started getting an eye twitch in the eyelid of my right eye just over 3 weeks ago. It was happening about 4-?

I had this twitch at least 4-8 times per day , every day until about a week ago. Instead my eyelid or possibly under my eyelid (its hard to pinpoint) starts feeling heavy and my eye feels sort of unfocused. This also occurs many times throughout the day then it feels fine again. I can't think of anything that's changed habit wise, and it doesn't seem to happen more when I watch tv or am on the computer.
