Medical Forum / General / Vision / April 2006Prescription increase
This weekend I had an eye test that showed my prescription needs to be changed from -2.25 left and right eyes to -2.25 left and -3 right. My question is this – till now I have worn glasses just part time but this seems a strong prescription for my right eye, will part time still be an option for me? Hi Anna, you didnt write in details that how much vision you had in your each eyes before thisnew glasses, & after how long you are changing your new glass? I am Gargi, Orthoptist, you can mail me ( gargi.cal@gmail.com) for any type of information regarding youreyes, Thanks, > This weekend I had an eye test that showed my prescription needs to be > changed from -2.25 left and right eyes to -2.25 left and -3 right.

[quoted text clipped - 6 lines] > Message posted via MedKB.com > http://www.medkb.com/Uwe/Forums.aspx/vision/200604/1 If you still don't get any headaches (or are not squinting) by wearing your new glasses just part-time, stay with it. Most of my patients over -2.00 d usually wear their gl's (or cl's) fulltime. Going from -2.25 to -3.00 (right eye) is a pretty good change though. frank >> This weekend I had an eye test that showed my prescription needs to be >> changed from -2.25 left and right eyes to -2.25 left and -3 right.

Some people are not visually sensitive, that is, being uncorrected/undercorrected does not give any symptoms whereas some individuals go nuts over a .25 d change. frank >>> Won't a 3/4 diopter difference between the prescription make going without >> glasses rather uncomfortable for her?

But I am thinking that one eye may need an upgrade in prescription - maybe that's the reason? Or would you just describe me as 'visually sensitive'? > I am a contacts wearer with -2.25 and -2.75 and do find the difference > uncomfortable if not with glasses.

So it's the actual amount, more than the aniso, IMO, that makes it uncomfortable for you not wearing your cl's or gl's. frank >> I am a contacts wearer with -2.25 and -2.75 and do find the difference >> uncomfortable if not with glasses.

Obviously he wears glasses all the time. If someone had a very mild prescription like -1 what would be the maximum difference they could tolerate before glasses became an everyday necessity? > I see someone with a minor prescription in one eye and significant in the > other. What, exactly, is "minor" and "significant"? > Obviously he wears glasses all the time. Obviously, he would *not* wear glasses. They don't work. People with a big difference need to wear contacts. The brain is unable to "fuse" the images together. > If someone had a very mild > prescription like -1 what would be the maximum difference they could tolerate > before glasses became an everyday necessity? My eye doctor told me that a difference in refractive need between the two eyes of 2D often caused problems with wearing glasses.

Actually he *does* wear glasses - one lense has hardly any prescription, the other a very strong one that sticks out behind the plastic frames. You misunderstood my 2nd question - I meant if someone had a -1 prescription in one eye and something stronger in the other, what would the prescription in the other eye need to be before it was necessary to correct it fulltime? ie how much difference can you go with? > >> I see someone with a minor prescription in one eye and significant in the > >> other.

Somebody with a big difference *cannot* wear glasses and have binocular vision. I've been there and done that. SignatureDan Abel dabel@sonic.net Petaluma, California, USA
