Hi, I have -1.50 cylindrical power in both my eyes. Doctor suggested that I wear tonic lens of -1.25 power (bausch and lomb). But my vision would get blurry every time I stopped into dim light area (only when I had tonic lens put on me), I consulted my doctor about this, he said my eyes seemed fine. Now doctor says that I can use the regular lens (spherical) of power -0.75, which I tried, but I could not see clearly as the power was too low (no blurry vision during dim light). Is it okay if I tried to get -1.25 spherical? Would it harm my eyes/vision? Also why does vision become blurry in dim light if contact lens are worn?
