I have to have regular eye tests with Diabetes, and go to Specsavers. My eyesight was superb for modelling in my teens but needed glasses for distance. Over the decades my eyesight has gradually shifted so I no longer need glasses for driving etc, but has become naff for close up detail work.
I can still read the eye chart to almost the bottom line, even for reading distance, so I asked them to make some glasses for 4 inch focal distance work. Some raised eyebrows, but they did, and I got an extra pair free.
Now when I need to see very close up I use the special glasses, and have a spare pair in case of damage.
Wonderful. Since then I can detail as fine as I want
