This is a cautionary tale about settling for 1-4 doctors' opinions. I had cataract surgery 2 yrs. ago. The first went fine, but after the 2nd, I literally could not see my hands in front of my face, nor the dials on the cooktop, nor the labels on my meds, the reading on the thermostat, etc. I went to 4 ophthalmologists, 2 optic nerve specialists, etc. After those two years of not being able to "literally"see my hand in front of my face, I went on a hunch to a Vision-4-Less optometrist. Within 20 minutes, he had my CORRECT prescription. As I sat there dumbfounded,he explained that I had previously been near-sighted, and "they" had inserted a lens for farsighted vision. The original prescription was a 2.25 correction, and after his test, it was diagnosed as requiring a 7.75 correction! Good news... after 2+ years of not being able to see whether my fingernails were clean or not, I threaded a needle without the use of an Ott light/glasses/and a magnifying lens.
NEVER take "no" for an answer, if you are not receiving the care you feel is needed.
