I am physically farsighted and can see everything crystal clear if it is an arms length or further away. Things start to go blurry as they get closer than that. I used to be 20-20, but age has caught up with me.
This loss of focus is not macular degeneration, because I have not lost central vision. Rather, this is just age-related farsightedness (presbyopia) where my eye lenses have lost some of their flexibility. This is very common.
It is so common that reading glasses to correct this have been available for centuries. So, it was off to Walgreens. They have several kiosks full of reading glasses of different corrective power and size and shape. I put on a pair of +1.50 glasses and looked at a reading sample. Wow! Crystal clear. I got a pair of rimless flex-hinge glasses for under $20. It was well worth it. I can now read books at a comfortable distance.
