how magnified will my child’s eyes be in glasses?

One question I see a lot is how different will a child’s eyes look when they’re wearing glasses, especially if they have particularly high prescriptions.  It is true that glasses will change the appearance of eyes: nearsighted lenses will make the eyes appear smaller, and farsighted lenses will make the eyes appear larger.  The higher the prescription, the more noticeable the effect.  Getting high index lenses will make the effect much less noticeable (they’re also thinner and lighter).

Zoe in her highest prescription of +6.25

In my experience, the effect was far less than I feared.  While I noticed Zoe’s eyes looking a little larger in her glasses, they never appeared “bug eyed”, and I am guessing that someone that didn’t know Zoe wouldn’t have noticed it at all.  From looking at the photo gallery, I think this holds true for most prescriptions, but that’s where I need your help.  For one, I know that Zoe’s prescription is only moderate, and that many of you have kids with a higher prescription.  But I don’t know what the prescriptions are for any of the pictures in the gallery other than Zoe.  If you have a child with a prescription of greater than 8 (I’m looking for both nearsighted and farsighted prescriptions, so greater than +8 or -8), would you be willing to share a picture of them in glasses and what their prescription is (or let me know that their picture is in the gallery) so that I can give parents an idea of how much or little their child’s eyes will be distorted by the glasses?

    Hi Ann, Paris is -4.5 in her right eye and plano in the left and with that script you really can’t tell that the right eye looks a tiny bit smaller. You would only notice it if you knew and even then it is very minor. I also pay for the thin lenses and would pay whatever it took to make sure they are as light and thin as possible as I think it makes a huge difference to the appearance to the eyes and especially for the higher perscriptions. If I didn’t get the thinner lenses it would be very noticable and the lense on that side would be very thick. Paris has beautiful big blue eyes so I hate the thought of her glasses which are a minus lense making her eyes appear smaller :)

    I’m emailing you a more recent image of Bennett, he was at -12/-8 in the photo and I don’t notice any distortion with the glasses or a discrepancy between the two eyes even with the big difference in strength.

    My son is -7.5 / -18. Yes there is a difference, the reality is that yes you can see that the left eye is smaller, but truly not so dramatically that it is distracting. he looks good.

    stick to round, small lenses because for nearsighted the thinnest part of the lens is the center. With a larger lens you get more thickness at the edges

    Thanks GeorgeB, you are right, I think stick to small round lenses too, definitely gives the best appearance. Your son looks great!!
    Did your PO say anything about going to contact lenses at a young age for your son becasue of the high script and difference between the eyes? Ours seemed to think around eight or nine would be appropriate for Paris to go to a contact lense in her weak eye?

      Ingrid, we may consider at around that age too. His PO had mentione dit in the past, but circumstances would dictate whether we try sooner, if at all..

    My daughter is +8/+7 and her eyes look slightly larger in her lenses but not huge… Here is a link to a comment I made in September regarding a similar topic – there is a link at the bottom (glasses) to a photo of her eyes in her glasses.

    I have just found out that my almost 3 year old has to have a +8 lens in his glasses and this is only his second pescription.
    This came as quite a shock to me as I had no idea that his vision was so bad up till the squint appeared at around 2 years old. Dose this mean he has had this as a baby and I never noticed!?
    Also, anyone know if an operation is nessasary? (Because I cant get the doctors over here to talk to me about that!)
    P.S Great web site! This has been great help to me, since I feel that there is know one to talk to about this kind of stuff who is in the same position.

      Hi Tracy, That’s a really good question about whether your son’s hyperopia was always present, and honestly, I don’t know. I know that many kids seem to develop strabismus (a squint) at age 2 or 3 that’s due to hyperopia, but I don’t know if that’s due to a change in their refractive error, or if it’s because their hyperopia is finally manifesting itself as eyes crossing. If anyone else knows, I’d love to know the answer to that, too.

      If his eyes are straight while wearing glasses, then no, there should be no need for an operation. I have read that in 3 out of 4 cases, no surgery is necessary.
