AS a Type I, my doctor advised me strongly to start wearing glasses and stop wearing lenses. Because they would apparently increase the risk of early blindness even more.
I'm not sure whether you or my wife need a new eye doctor. Hers knows she is diabetic and is doing extra screening watching for any possible damage from the disease but has never said anything about her contact lenses being a problem. Other than while sleeping she always wears her contacts.
There's a whole story to this, but that is a little too private to share on the web :)
The larger story is, that lenses can damage the eye (tiny scratches, little infections); regardless of Diabetes. Diabetics have increased risk of badly healing damage, especially wrt fragile nerves (toes, eyes, hearing). The increased risk that anyone has for infections and problems when wearing lenses, is only so more dangerous to Diabetics.
