Power prescription

2017-07-21 15:08:18
I have problem seeing far things. One doctor prescribed glasses with power OD : sph -1.25, cyl +0.50 axs 64, OS : sph -1.25, cyl +1.0 axs 89, which i find bit uncomfortable. I think its not accurate. When i tested again, another doctor gave right : sph 0, cyl -0.50 axs 160, left : sph 0, cyl - 0.75, axis 180 Why is second testing gave CYL negative. Is this okay?
