Early detection is the first step to an effective program. Diabetes Mellitus is a condition which causes a person's blood sugar levels to be elevated. Over time, these elevated blood sugar levels can affect a number of organs throughout the body. These include the heart, nerves, blood vessels, kidneys and the eyes. The eyes can be affected in different ways.
Diabetes can cause transient blurred vision when a person's blood sugar levels fluctuate wildly.
Too high or too low blood sugar levels will change the amount of water in the eye's lens, in turn causing a change in one's vision. Stabilizing the blood sugar will prevent this. Diabetes also can cause cataracts. A cataract is a cloudy or opacified lens inside the eye. This cloudiness or opacification leads to blurred vision.
