My 25 year old daughter has one eye that is -2.75 and one eye that is -.75.
The eye pro says its up to her whether she gets glasses but I think the worse
eye is quite nearsighted. I wonder what the opinion here would be on whether
she should get them and how much she would need to wear them.

Sure, but what problems does she have without glasses?
If she's opposed to wearing glasses, a "pro" would only be concerned that
she meets legal requirements for driving, so we can assume she sees 20/40 or
better in the good eye, or she doesn't drive. She probably doesn't drive at
night. She probably shouldn't, without correction. Other than driving, her
distance vision might serve her just fine. At 25 her myopia may still
increase, but probably not, and wearing glasses won't make any difference.
Her glasses minify, much more in the -275 eye, and glasses can feel weird
and hard to get used to. Also, both her eyes work _better_ than normal at
very close distances, and glasses take that away from her. It's possible she
got a distaste for previous glasses, even if they were "exactly right."
Contacts don't distort the optics like glasses do. Folks like her are often
very happy wearing a single contact lens.

She went to get her eyes tested because she felt she didn't see quite so well
as her friends, she said like far across the room and bus numbers. So the eye
doctor said it was up to her and she didn't get any glasses because she
thought he was saying it was unnecessary. She does drive but said for most
things she can squint her eyes a bit which helps. Should she get another test
for a 2nd opinion?

She already got a good opinion.
Instead, spend that money on a simple pair of glasses so she has the option
to wear them when feels the need.

She doesn't need to waste money on a second opinion. She has a good
first opinion which is "its up to you whether you get glasses or
not". She can see reasonably well with both eyes open and no glasses
and a little better with glasses. If she doesn't like squinting or
finds the distance blurry then she can get glasses. No one is going
to tell her that she must get glasses unless she fails the local legal
driving requirement and even then she will simply be told that she
must wear glasses to legally drive; whether she wears them for other
activities is up to her.

Judy is both accurate and correct in this statement.
I agree with her.

I'm curious as to why you are recommending a single lens. I've worn a
single lens, and I've worn two. Contacts are a hassle, but the
difference between one lens and two isn't much different, maybe a few
seconds for insertion and removal.

There's a lot we don't know, but here are some reasons:
One is that the -275/-075 rx may be 025 more than really necessary. If so,
the -075 eye actually needs -050 and -050 contacts are often not worth the
effort.
Another reason is that people with this scrip often declare "my good eye is
just fine. I don't need anything for it." So it's much easier for them to
accept the need for one lens, rather than two. Needing two contacts means
the problem seems twice as bad.
Another, probably the biggest reason - she's used to undercorrection and may
find full correction distasteful. Leaving the 075 eye uncorrected retains
some of the near advantage and makes the transition easier. Then, 15 years
from now, monovision requires no "adjustment" at all.

Which eye would you correct? One could argue that correcting the left would
provide the most comfort, especially if the she has been this anisometropic for
numerous years. Correcting the right or both would provide binocular vision.
Your thoughts?
>It's possible she got a distaste for previous glasses, even if they were "exactly right."
Possibly, although how many times do we see this type of Rx fit properly? To be
sure, CLs would be the preferred solution compared to spectacle lenses (both
eyes corrected), eyeglasses would probably be tolerated if they are fit close to
the eyes with accurate vertical OC positioning.

I didn't see a reference to left or right, but I was talking about the -275
eye.
In real life I'd probably put trial lenses on both eyes and overrefract.
Then I'd check for discomfort/phoria at near and suggest a trial run for a
week or so. If there are near problems, the first thing to do is remove
the -075 lens.

Tolerated, maybe, but probably not comfortable reading in down gaze.

The simple answer is if she can do everything she has to in her
daily routine without glasses, then no. It's a matter of her own
comfort. She can always get glasses down the road.

Given the difference, I'd say contacts are the best bet. As Mike
Tyner pointed out, glasses shrink images, and the one eye would look
quite a bit smaller than the other (there'd probably be around a 5%
difference in apparent size betwen the eyes, which is something her
brain would need to get used to). This effect is diminished to the
point of non-existence with contacts.
I'm not an OD (unlike Tyner), but I think two contacts, to full
correction, would be better. She is, after all, only 25, so
presbyopia (losing the ability to focus on near objects as the lens
gets old and inflexible) is 15+ years away. She may not really
appreciate what she's been living with until full sharpness of vision
is provided. She can always back the prescription up, if easier near
vision is desired (which would obviate the need for two contacts if
you go back far enough).
Overall, I can't imagine going without correction in her situation.
-2.75 in that one eye is pretty severe. That means objects start
becoming blurry a bit more than 14 inches away from that eye. A great
eye for extended periods of reading, but not so good at other times.

Thanks everyone. She has the prescription and I'll relay this conversation to
her and suggests she gets some glasses to see what difference they make.
Nancie - 22 Dec 2007 19:40 GMT
Just to follow up, my daughter picked up a pair of glasses yesterday and is
charmed by the clarity they give her. From what you said here it seems that
she could have gone on as she was but what getting the glasses has proven is
that they make a big difference. The eye doctor suggested she wears them all
day for a while to get used to them and she hasn't found any problem with the
difference between the two eyes fortunately. Like you say the one eye looks
different because of the strength but it doesn't seem to bother her so all's
well and thanks again.
