Correction for peripheral vision?

    I have a macular hole in one eye, so the eye doc doesn't bother to try
    to prescribe for it. He recommends a balance lens.

    While I cannot read, my peripheral vision is unimpaired, and
    even "balanced", it's pretty much a blur.

    Seems to me that if the eye doc had a big poster with thick lines on it,
    I could tell him when I could see them the best with my peripheral sight.

    Does anyone know of any ophthalmologists/optometrists who do peripheral

    I am not a vision health professional. I think you are going to be
    disappointed. Just what do you expect?

    If there were an intelligent designer for eyes, they did not design for
    high acuity peripheral vision. If your central vision is shot, you have
    to settle for what you can get peripherally. The concentration of cones,
    to almost complete absence of rods is in the macula. It would be
    possible to form sharp images on some peripheral portions of the retina,
    but even if that were done, you will not see sharp images.

    He doesn't need to do a peripheral refraction, he can determine your
    central refraction by retinoscopy or by auto refractor; peripheral and
    central refraction are close to the same. Next time in, ask him ot
    write your actual refraction, not balance for that eye and demo with a
    trial frame and trial lens so you can tell whether the difference is

    When you take it to get filled, have the optician check the actual
    power of your current "balance" lens and tell you if the actual
    prescribed power is much different. Since both eyes are usually close
    in power, and a balance lens is chosen to be similar in power to the
    other eye, your current balance lens may be pretty close to your
    actual prescription. If there is a large difference, then you can get
    it filled.

    The peripheral retina is not capable of good acuity and you will
    likely find that the periphery is not much clearer but it is worth a
    try if there is actually a difference.

    What is a "balance lens"?

    My wife has one of those. It means that there is no correctable vision
    in that eye, so just make the lens so that it looks like the other one.

    A macular hole is reparable by a surgery. Why don't you go for it
    instead of refracting your peripheral vision and/or using a balance

    [I am not a vision professional, but I have had a macular hole (stage
    3) which was successfuly repaired and I regained my central vision.
    Presently my corrected vision in that eye, after a mac hole, retinal
    detachment and a cataract, is 20/40, and actually I "achieved" 20/30
    in my last eye exam, which impressed my ophthalmologist, but I know it
    was not really real -- I simply have become a good guesser :) ]
