question: Hello doctor, I have been using only one eye since birth. This is a result of a medicine that my mother took when I was in her womb. My right eye is normal, but the left has a squint. I can see a little light in my left eye, but I cannot really use this eye for seeing. By this time, I got another problem with my one and only eye. I cannot clearly see things that are 10 meters away from me. I am afraid to lose my sight. I need your help.
