What's the reasoning behind being over 40? I recently complained to my optometrist that I was having a harder time seeing things up close and he prescribed me weaker lenses for work/reading. My regular prescription is right around -7 in both eyes. I'm not over 40.
Presbyopia - the lens in our eyes begin to harden at age 40, making it harder for our eye muscles to "squeeze" the lens to focus. Presents itself as blurriness and eye strain. We usually encounter a change in our Rx during this time too, sometimes needing a weaker Rx (counterintuitively).
Would love to chat about your experience in any case. I'm at jbornhorst [at] gmail.com if interested.
My optometrist set the adjustable lenses to what he thought was in the right ballpark and then had me read the chart at my requested distance for the computers lenses. A few adjustments, and done. They're perfect! Bonus: text is a bit bigger now, and I can read smaller fonts than I could before getting computer glasses.
The downside of this is that I now find it very difficult to read computer screens and my phone while wearing my distance lenses. The practice of holding things further away to be able to read them always was, I suppose, inevitable.
