Cylindrical power in eyes. Glasses.

Hi, I am facing problem of dim light in left eye for last three months. Three months ago I was having headache feeling like severe pressure and stiffness in head and neck after covid. While I was rotating head and stretching my neck, I got sudden jerk and burning sensation at left side back of my head and I became unconscious for few minutes. I consulted with neuro and got mri done, but no abnormalities found. I consulted with opthalmologist and findings were- fundus- normal, peripheral exam-wnl, no papilloedema, no hypertensive changes, no diabetic retinopathy, cylinderical power OD- +.25, OS- +.75. Earlier both of my eyes were 6/6. Doctor advised me to use glasses if I feel required. I always feel pressure behind eyes , more behind left eye, pressure on my temples. My eyes struggle more to see in cloudy weather or in low lights and can't focus easily together. Pls suggest tests/treatment for dimmer light problem in left eye even after using glasses.
