Over time, uncontrolled diabetes can have a negative impact on your vision and cause damage to your eyes. Controlling your diabetes and maintaining your eye health is accomplished through management of one’s blood sugar (glucose), blood pressure, and cholesterol. It’s highly recommended to not smoke and EVERY YEAR be sure to have a dilated eye exam. The dilated eye exam can often identify eye problems early and BEFORE much vision is lost. Unfortunately, diabetic eye disease damage occurs with no warning signs.
