I have had very high myopia (-9D) for most of my life. Used contacts for nearly a decade starting 30 years ago. Went back to glasses after that. Would have eye strain issues due to 12+ hours on the computer every day. When I turned 40 and started have issues with presbyopia, I asked my opthalmologist (who also writes my eyeglass prescription) during my biennial checkup why he has been prescribing powers based on how well I can read the tiniest letters on the board when I spend most of my life reading stuff that is two feet away. He reluctantly suggested that I could use glasses with 1D shaved off the powers in the prescription. I had already done this before I asked him about it. And it has been a big help as the strain disappeared. Things get blurry at a distance with the new glasses, but it is not as if I am driving at night on the roads or anything.
