I’ve just started EM journey because my 6 yr old recently been diagnosed myopic while I’ve been myopic since childhood. I’m doing mainly measuring eye sight and spending more time outdoor. I need help with a couple of things before tackling prescription.
- Plus lens: I understand that it may change focal plane but why is it that according to Jake’s video, he would do it if it’s for a child but not for adult?
- I have presbyopia (+1.75) but not wearing correction for it. My myopia (according to optician, although my.measurements varies) is -1.25 R and -3.25L. I understand that I need to be careful with reducing for differential so as not to make presbyopia worse. Jake said the ‘gap’ need to be small. I don’t get what gap is that. Is it smaller cooperated decrement rather than the suggested 1-2 diopter? May be I should skip differentials and just start with normalised as I’ve been taking my minus glasses off for close up anyway.
