Before being diagnosed and eventually treated for their diabetes, some diabetics experience sight problems due to their disease. These problems may be blurry vision, difficulties to focus and sudden near- or farsightedness. These problems may also be present during the first months of treatment. This might cause unnecessary worry, but is something that occurs to many diabetics, and it is due to the high blood sugar levels, that affect the eyes’ lenses. It is important however that the patient, if he or she is already using contact lenses or glasses, doesn’t walk right away to the local eye care professional to try out new lenses to cure this unexpected problem. When the treatment sets in, and the blood sugar goes back to normal, so does the changes of the lenses, and the vision is very likely to become normal again.

Diabetes patients otherwise usually don’t have any trouble using contacts or glasses, since the disease rarely affect the eyes. Any type of contact lens, like soft lenses or extended-wear lenses, is not likely to cause any problems. It is important however to have regular contact with the eye care professional, to make sure that any eye problems will not return and become permanent.
