Strange vision problem

I'e got this extremely weird problem: My refractive errors are as
such:

OS: +1.00D
OD: +4.50D

Now, my OD gave my, as you would expect, a -1.00D lens for the left
eye, and a -4.50D lens for my right eye. But the left eye only gets
slightly better, while I can't notice anything w/ my right eye.
But...when I swap the left and right lenses, my left eye becomes
20/20, and my right eye, while still far from that, gets a small
improvement. How can this be? Also, when I put the new left eye lens
on my right eye, and flip it backwards, aside from it needing a slight
power adjustment and a weird fisheye effect, my right eye is noticebly
improved. What's with this?

Thank you!!!!

Dear Dark Proto Man,


I'e got this extremely weird problem: My refractive errors are as
such:

OS: +1.00D
OD: +4.50D


Dark> Now, my OD gave my, as you would expect, a -1.00D lens for the
left
eye, and a -4.50D lens for my right eye.

=============

Otis> Then your OD gave you the incorrect lens for your
stated refractive error.

Otis> Using the Donders theory, you should have been
provided:

OS (left eye) +1 diopter lens for the +1 error. (Or no lens
if you had 20/20. This would be optional, if you
have 20/20.

OD (right eye) +4.5 diopters lens for the +4.5 diopter
refractive ERROR. This would be a classic perscription.

Otis> Did your optometrist explain WHY he was
prescribing a -1 and a -4.5 diopter lens?

Just one man's question.

Otis

Something's wrong with the above statement.

You just have to learn Otis-speak. Makes perfect sense to me. I doubt
that it makes sense to whoever refracted him.

No, I had the optician check my lenses as soon as I got them w/ a
lensometer; he said they matched the prescription.

Dear Protoman,

Optometrist Judy is correct about this.

Dr Judy will be thrilled to read Otis' approval, I'm sure.

Dear Dark,

The easiest solution is this:

Call the OD, or ophthamologist and ask him
if you are farsighted or myopic.

That will resolve the issue, pronto.

If the prescription is "positive", then you have
plus lenses.

A positive lens will bring sun's rays of light to a point.

A +1 to a point at 1 meter. You could hold the lens in
sun light and see if it forms a image of the sun at 1 meter.

If the light rays diverge (no image), then you have
a negative lens.

Hope this clarifies this issue for you.

Otis

I am myopic. I need minus lenses. My left eye is my good eye.

Pervious: I'e got this extremely weird problem: My refractive errors
are as
such:

OS: +1.00D
OD: +4.50D

Otis> Then these values should be:

OS: - 1.00 Diopters (Refraction)
OD: - 4.5 Diopters (Refraction).

The lens you have must be minus to clear your distant vision.
