How Does High Blood Glucose Affect Vision?
High blood glucose pulls fluid into the lens of your eye, causing it to swell and change shape, which can blur your vision.
It can be challenging to focus clearly when glucose levels are high.
These changes might last for days or weeks until your blood glucose returns to normal.
You may notice difficulty seeing colors vividly or issues with night vision.
How Does Low Blood Glucose Affect Vision?
Low blood glucose can affect your eyesight, as your eyes and brain may not get enough energy to function well.
Can cause dizziness, confusion, or even loss of consciousness, all of which may disrupt vision.
Once your glucose level stabilizes, your vision should improve.
How to Protect Your Vision
Protecting your vision is essential, especially if you have diabetes.
Aim to keep your levels within the recommended range.
Visit your eye doctor at least once a year, or more frequently if advised.
Contact your doctor if you experience symptoms like blurry vision, floaters, flashes, or spots.
Eating nutritious foods and staying physically active helps keep blood sugar steady.
Including insulin or oral diabetes medicines if needed.
