Hello doctors, I want to know that how does the axis parameter in the lens power impact the eyes. I am a 28 yr old female and having myopic eyes. I wear powered glasses. I recently went for an eye checkup and optician said that there's no difference in the eye power and I can continue with the same specs. then I got checked my glasses for their power. In the hospital the optician checked it manually (since the machine was not available there) and I was provided by the parameters as follows Left eye -2 (sph)/-0.5 (cyl)/ 120 axis Right eye -1 (sph)/-0.5 (cyl)/70 axis However I again got checked the power using machine and the parameters are as follows. Left eye -2 (sph)/-0.5 (cyl)/ 130 axis Right eye -1 (sph)/-0.5 (cyl)/50 axis The only difference in both the powers are in the axis values. I am supposed to have a new specs but I am not sure with which power I should go for. Kindly help. Thank you
