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
refractions?

Thanks.

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.

Thanks for responding.

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
noticable.

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
lens?

[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 :-) ]
