There is a huge difference in right and left eye for my son.
**I planned of reducing 1 diopter from his current prescription. I got this doubt of whether i can take spherical power to 0 (in his right eye) as it is just -0.5.
But, according to the sessions, we need to add 0.5 diopters to spherical if we reduce a complete 1 diopter in cylinder. So in that case, in his right eye, i need to add 0.5 diopters for reducing 1 diopter in cylindrical. But this would also not bring him a change or challenge in clearing the blur. **
Will it be right do so to take spherical to 0 ?
