Have you ever gotten up from the table after enjoying a meal and noticed that things appeared fuzzy or blurry? If so, you may have experienced a temporary spike in blood sugar that affected your eyes.
If your vision is often blurred after meals, you should schedule a visit to your optometrist and general practitioner to rule out diabetes and other conditions.
The Link Between Blood Sugar and Vision
Diabetes is characterised by excessively high blood sugar levels. In some people it causes food to be digested faster than usual, leading to rapid spikes in blood sugar. Elevated blood sugar can lead to fluid to build up in the eyes, resulting in blurry vision.
The eye's natural crystalline lens and cornea are responsible for focusing light onto the retina for clear vision. The lens changes its shape to accommodate focusing on near or far objects. In some cases, when the eye swells due to excess fluid resulting from the high blood sugar, it temporarily doesn't focus light with the same accuracy.
Foods that are high in sugar and other carbohydrates are most likely to cause blood sugar to spike. Some examples include:
- White rice and pasta
- Most breakfast cereals
- Potatoes in all forms
- Sugary sodas and beverages
- Candies and baked goods
- Fruit juice
Other Possible Causes of Temporary Blurred Vision
Temporary eyesight changes don't always mean diabetes. Intermittent blurred vision can be caused by other problems or conditions, including:
- Carotid stenosis
- Certain medications
- Eye strain
- Pink eye (conjunctivitis)
- Macular degeneration
Many of these conditions will also present with symptoms other than blurred vision, so be sure to be open with your optometrist if you experience any unusual visual symptoms.
If you notice blurred vision only following a high-carb meal, it may be worth tracking your meals and symptoms to try and find a pattern. This information will be valuable for your optometrist and other health care professionals.

How often do I need an eye test?
The American Optometric Association recommends that adults have their eyes checked by an optometrist every 1-2 years. For high risk patients, patients who wear glasses or contact lenses, or those over the age of 65, annual eye tests are recommended. Certain conditions like diabetes may make it necessary to visit your optometrist more often.
Does being diabetic make a person more likely to experience vision loss?
Diabetes can negatively impact your eyes in more ways than one, but preventing vision loss and blindness is becoming easier with new technology and treatments. Having undiagnosed diabetic retinopathy puts a person at a much greater risk of going blind. If you or a loved one has been diagnosed with diabetes, be sure to schedule regular diabetic eye tests including retinal scans, to significantly reduce the chances of experiencing permanent vision loss.
