    Greetings Jake and everyone,

    So I had to have one of those rehab breaks you mentioned. I had a number of serious life events happen all in a row (including broken bones and surgery, relationship loss and moving twice). It was pretty overwhelming, actually.

    So now things have settled down and I’m returning to my eye rehab.

    I recently had a retina exam. No change in lattice degeneration. She said my eyes look “great”. Which isn’t necessarily “great” by your standards, but at least is better than her saying they don’t look so good. Except for still hovering around -7 each eye, no astigmatism. They do a cursory prescription evaluation during the retina exam. I used my pair of glasses which is -6.75R, -6.5L. They said I tested 20/20 except that each eye missed a few letters on the 20/20 line.

    Things I did well during my break:
    Retaining the habit of never using full prescription or normalized for close work.
    Continuing deliberately taking time for distance vision.
    Usually not very much close up work each day, with occasional exceptions.
    On average, overall reduction in screen time/cell phone use.
    And, I did get my eyes medically checked by retina doc.

    Things I think I screwed up & am now addressing:

    In my stubbornness to not increase diopters I think I’ve been creating a bit of eye strain and blur habituation–I think those two things alternate during my day.

    Also, I got into the bad habit of tilting up my glasses to functionally increase their strength, especially at night. I know–terrible idea. Screws up focal plane. It’s a hard habit to break, but I am trying now.

    In the last month or so I noticed that my left eye, which historically has always been 0.25 diopter less bad–is now more blurry in the glasses, than the right eye. (The right eye has 0.25 greater prescription strength.) Both eyes checked out fine at the doctor. But for some reason my left eye is now focusing very slightly less well instead of slightly better. If I increase focal plane/prescription strength, I think it does seem to improve the sharpness of what I can see out of it. (My eyfriend a are currently tired as I type this before bed, but I recall noticing this earlier.)

    Also, my Zenni optical glasses are a bit scratched/battered and could probably stand replacing.

    Action items I’m taking:

    Consistent breaks after 20 min close work;
    Improving lighting in my office;
    Any Internet time at home at night will now be using a TV set (so that I’m not so close to an iPad or computer screen);
    Taking more walks;
    Working at blur horizon;
    Trying to push focus;
    Putting the eye chart back up.

    Questions for you:

    Am I overlooking anything that I need to be doing, here?
    My current differential is around -5.75 R, -5.5 L (I’m away from home & cant look it up exactly). Is that ok?
    My normalized is -6.5R, -6.25 L.
    I can’t find the pair that I think is full prescription: -7R, -6.75L. So my current full prescription is -6.75R, -6.5L. Which is slightly blurry but I think I still have some ciliary strain on board.

    What do I need to do to stabilize and sort this out?

    Thank you!!

      Hi Andrea,

      Sorry to hear about the troubles. Glad you made it!

      Nice that you maintained the key habits. That’s what it’s all about! If habits survive all that mayhem, you’re on the right track. From here, little, little tweaks. Exactly as you outlined. Break the few bad habits, make slight improvements.

      Differential is fine as long as you stay ergonomically comfortable. Normalized yes, as long as you’re getting good active focus with it.

      Thanks Jake!

      Have you ever heard of the stronger eye switching like that?
      I’m glad they checked out ok at retina doc, at least structurally in terms of what she could see. Could it be some new astigmatism thing?
      I get the sense it could possibly have to do with my glasses really not being ideal.

      Their non-retina eye exam was kind of cursory. I did learn, no glaucoma; and they thoroughly examined the inside of my eyes.
      Would it be useful to go get an eye exam with upsdated prescription on top of that, from a standard optometrist?

      Also, when I feel like my eyes are just plain straining in response to too much blur, not close up work, should I increase prescription? Examples: talking with a client or driving. Where there is demand on my eyes, not just casual or relaxed.

      Sometimes extra strain is ok – if it’s working as more significant stimulus for short periods of time. Key here is to look at whether you’re working harder for active focus, and getting it. If not, and if it’s too much too long, then maybe previous normalized can make sense to wear.

      Dominant eye is always the same in general but as we address artificial focal planes the ‘apparent’ dominance can switch. Normal.

      Dominant eye = the one my brain automatically “goes to” first.
      In my case, that’s my left eye. Historically it has needed 0.25D less correction than the right eye.

      So you’re saying it’s normal for my dominant eye, which used to have slightly sharper vision, to now be slightly blurrier than the other one?

      It did seem to improve when my eyes were less tired in the morning. Sometimes it’s difficult to tell.

      Yes that can happen also. Short term as your refractive state changes, especially.

      Can it be related to creating too much eye strain, like, by not using the correct normalized or differential?

      I first noticed it about 6 weeks ago. Is that considered “short term”?

      Yes it’s ok. Just make sure to take it easy, maximize outdoor casual active focus time, and not over-focus on trying to replicate or obsess (for lack of better word) over trying to notice single eye performance.

      With consistency and good habits (especially that outdoor time), both eyes will get to performing well.
