Eye focus problem. To see only object 1.

I felt a small jerk in my left eye few years ago from that time my left eye vision could not adjust properly to see particular object. It's not blurry or painful. if I can say more precisely then if I am seeing front where 3-4 objects are there, I am not able to see only one object particularly, all the objects I can see but my left eye not able to adjust to see only one particular object and if I see object 1 then remaining objects and the objects which are at back of object 1 they also are properly visible and my eye could not adjust to see only object 1.I know it's weird problem but I am telling wat I am feeling and I am done with basic tests including muscle balance.please help me find what's wrong inside
