Be careful that you don't set the Pick Box too large. Mine defaulted to 5 mm and it was a challenge to select the correct point when several are close together. Reducing it to 1.5 is better.
Another thing you might try is getting a pair of reading glasses that you can wear while working on your CAD projects. I have a pair of 2.0 diopter readers and they do help but be aware of the reading distance (your eyes to the monitor) to get the right diopter strength for you.
