Diabetes doesn’t just affect blood sugar—it can silently damage your eyes through diabetic retinopathy, a leading cause of blindness in adults. High blood sugar injures tiny blood vessels in the retina, the light-sensitive layer at the back of the eye. In early stages, there are often no symptoms, but over time, vessels can leak, swell, or grow abnormally, leading to blurred vision, floaters, dark spots, or even sudden vision loss.
Common warning signs include fluctuating vision, difficulty seeing at night, or faded colors. Risk factors include poor blood sugar control, long-term diabetes, high blood pressure, high cholesterol, smoking, and pregnancy.
The good news? You can protect your vision! Keep blood sugar in target (aim for A1C under 7% if possible), manage blood pressure and cholesterol, exercise regularly, eat a balanced diet, and quit smoking. Most importantly, get a comprehensive dilated eye exam at least once a year—more often if recommended. Early detection through these exams allows treatments like laser therapy or injections to preserve sight.
Don’t wait for symptoms—vision changes can appear suddenly. If you’re living with diabetes in North Liberty or nearby, schedule your annual eye exam at Blink Vision today. Early action saves sight!
