Medical Forum / General / Vision / January 2007Is it possible to stop progress of myopia in adult?
Is there any evidence that undercorrecting myopia in adults can reduce it - eg wearing -3 instead of -3.50 contact lenses? And is there a risk that wearing something too strong will advance myopia even in adults? I have one eye worse than the other which i understand is usual. Even after 40 it still creeps up a little each time I have a test.I wondered if I could reduce its progress by undercorrecting it a little but would be interested to know if anyone has any experience of this idea. > Is there any evidence that undercorrecting myopia in adults can reduce it - > eg wearing -3 instead of -3.50 contact lenses? No there's not, in fact one study even suggested that undercorrection can cause the myopia to worsen. > And is there a risk that wearing something too strong will advance myopia > even in adults? It sounds plausible at first but I'm not aware of any studies that actually support this idea. > I have one eye worse than the other which i understand is usual.

Sometimes people in their 40's who actually need reading glasses can develop a type of pseudomyopia but I don't know what's happening to your eyes without a lot more information. But to answer your question undercorrection of myopia shouldn't make any difference.

It would seem that you have undergone your own self-experiment many times. Every time your myopia increases, you are temporarily under-corrected. According to some people who have posted here recently, if you let it go it would level out at about -2.00, which is about 20/150 on the Snellen chart. :) DrG > I have one eye worse than the other which i understand is usual.

But, here is a more practical suggestion. There is some correlation between close work and myopia. If it is just the one eye that keeps progressing, you might pay closer attention to how you work, and if your close work is arranged to favor one side or the other, or if you have a binocular vision problem that predisposes you to favor one eye over the other for close work. |
