Question about an eye having better sight than the other Hello, 25 M. I developed myopia when I was about 12 years old. About 4 years ago I had surgery to correct myopia. The result was great but sometimes I felt that my left eye had still worse degrees than the right eye. 
Maybe because I spent a lot of time playing videogames and on the cellphone during quarantine, without spending almost any time looking at far objects, now I can clearly see that most of the day my left eye has myopia. I can't say if the difference is more or less than 1 degree with the right eye, but I was wondering if there is any exercise that I can do to recover that degree. Maybe he's getting "lazy" and I could try to cover my right eye for a while?
