When I turned 45 my eyes changed to the point where I would need the multi focal lenses and they work like a charm. For close up reading you look towards the bottom of the glass, where distance is at the top part of the lens and there are no lines on the lens like before. But for very close up reading like labels on bottles that are like a type 6 font! I need to still pull out my reading glasses to read the print.
I also wear the multi focal contact lenses that are out too and believe it or not they work pretty well the same but your told you need to either give a little on distance or close up in the way they are designed. But again for up close reading I still need the reading glasses for small font.
