I use minus 4.25 non driving time but when driving is not good enough my normal eye is minus five both eyes I stopped using minus five. Around six month ago. So since I drive most time should I use more than minus 4.25 would that take my eyes back to minus 5 again?
Re-up on what Bianca already shared and add that if you are not getting progress it is because you could maybe use more correction in your normz too… Being over corrected for a task (specifically a close-up static task) leads to increased myopia. Living in excessive blur is not helpful either, there is nothing to be gained by straining your eyes. As long as you are using proper diffs in close up your normz can (and probably should) only be .25 below your full correction.
