Double Vision Even After Wearing Glass.

Doctor, I'm 14 Years Old. I'm Having Double Vision And Blurry Vision. Doctor Told That I'm A Patient Of Myopic Astigmatism. His Prescribed Eyeglasses Reduced Blurry Vision Fully And Also Reduced The Double Vision Approximately 70-90%, But Not Fully. I Was Reported This To Doctor And He Told Me That The Remnant Double Vision (Which I'm Having Even After Wearing Glasses) is Normal And Will Presist. My Eyeglasses Power Are: LE-(SPH:-2.50,CYL:-0.50),  RE(SPH:-0.75,CYL:-1.00). I Had Experience To Wear Glass Before. And I'm Sure That The Glass Adjusted With My Eye. Doctor Checked Me Using Slit-Lamp. I Also Took A Second Opinion And The Second Doctor Told Same As The First Doctor. The Second Doctor Also Examined Me With Slit Lamp. Now, I Have Heared That Astigmatism Caused Double Vision Disappear Fully After Wearing Glasses. So, Why My Double Vision isn't Completely Going After Wearing Eyeglasses? What Should I Do in This Situation? Please Help, Doctor.
