Hi l am having cataract surgery soon with the vivity EDOF lens, l told my surgeon my main aim is to have good distance vision and l dont mind glasses for reading , my surgeon said he is adjusting by non dominant eye very slightly for near and dominant eye set totally for distance , l told him l dont like the idea of monovision because eyes might seem offbalance and hard to adjust to but he said it will only be a 0.5 D difference between the left and right eye and l wont even notice the difference between both eyes. He said the dominant right eye will be 19.5 and the left non dominant eye will be 20.5. Can you please explain what these numbers mean ? will these settings give me good quality distance vision in both eyes
