I am having headaches from glasses.

I was wearing glasses 3 years back and I had no problems. The powers were: RE: sph:-1.25 cyl:- 0.5 axis:10 LE: sph:-1.25 cyl: -0.5 axis: 30 And a year back, I started having headaches. So I went to the eye doctor and he gave me a new prescription glasses: RE: sph: -1.75 cyl: -0.75 axis: 180 LE: sph: -1.5 cyl: -0.5 axis: 30 For the whole year my eyes used to hurt and I used to squint and feel dizzy. So again I went to the doctor 2 months back and he gave me this prescription: RE: sph:- 1.25 cyl: -1 axis:175 LE: sph: -1.25 cyl:- 1 axis:30 But still I am having headaches and eye strain 😭😭 Can anyone help? I need to find the proper power of my eyes. And I need to get rid of these headaches and eye strain. Does anyone know the answers why am I having these eye problems 😔 I have wasted so much money in buying these glasses again and again but to no good results.😔
