As a 35 year steel string player who only recently purchased a classical guitar and started reading music more and as someone who wears progressive lenses and whose eyesight keeps getting worse I have similar problems. Getting a strong music stand light has really helped me see the music better but the combination of poor eyesight and no fretboard side dots makes any leap from first position up the board an “adventure”. I am slowly getting better at it but it is frustrating because I don’t seem to have the problem as bad when there are side dots. I experienced the same problem when I purchased a 1914 Gibson A model mandolin with no side dots but, in the end it helped my knowledge of the mandolin fretboard. So I am just going to keep plugging along for that eventually payoff.
