I have extremely bad vision. I went to Dr. Landon's office for years, then moved. I have yet to find a doctor who knows my eyes better than he does. He told me GP lenses wouldn't work for my eyes, and 3 other doctors said that they would. So i got them, and it turns out, they dont work for me, my pupils dilate too big at night. I also ordered some soft lenses from other doctors, and i've encountered problems every step of the way.
