The Correlation Between Diet and Blurring Vision

The Correlation Between Diet and Blurring Vision

The old tale that carrots improve your eyesight dates back to a British cover story to conceal that their pilots used radar. That falsehood springs from a broader truth that there is a link between dieting and blurred vision. A diet rich in nutrients and low in salt and processed sugars can be part of a comprehensive plan for healthy vision as you age.

Many forms of dieting produce sudden changes in blood sugar levels and levels of other nutrients. The changes can trigger intermittent dizziness, lightheadedness, and blurry vision, especially at the start of the diet.

Diet and Eye Health

The eyes are sensitive organs that depend on a rich supply of oxygen and nutrients to perform correctly. The macula, at the back of the eye, contains many light-sensitive cells and depends on a reliable blood supply.

Cardiovascular Disease and Vision

One benefit of a healthy diet is a healthy cardiovascular system with low cholesterol levels. Without healthy arteries, veins, and capillaries, your eyes cannot receive the oxygen, energy, and nutrients they need.

Too much salt in the diet can raise blood pressure. High blood pressure puts strain on the blood vessels. The blood supply to the eye affects the retina, lens, and eye muscles. Each of these components is vital for clear, focused vision. Diseases and conditions that disrupt that blood supply ultimately affect vision.

Are Your Employees Eating Properly?

If you are a small business owner, you count on your employees to be at their best when they are on the job. One link between dieting and blurred vision is that reducing your food and water makes it harder for the body to cope with stress. Even momentary blurred vision can cause accidents, injuries, property damage, and even liability. Protect yourself and your employees by helping them get health care, vision care and nutritional guidance.
