Can you tell me is there a way to make a lazy eye normal?

Yes but not at your: Age. The sooner the treatment starts the better the results. If completely treated by age 4 ; eyes are straight then you develop 3d vision ; may become completely normal. 4-9 years of age is still golden for treatment of amblyopia. Recently there have been studies that show lazy eyes are treatable till age 18. Although the gain may be less ; less but there is permanent gain up to that age.
