Excessive sugar intake is one of the biggest causes of diabetes and teeth infection. While these two have been the subjects of many studies all over the world, and adequately documented, what many miss is the toll excessive sugar in daily diet takes on eyesight.
Protecting your eyes requires more than just medication. From what you eat to how often you move, every daily choice plays a part in preserving your vision.
Health risks of diabetes
Diabetes is far more than a sugar issue. It's a full-body condition with severe consequences. One of the most serious, yet under-discussed, complications is its impact on vision. “Diabetic eye conditions like retinopathy, glaucoma and cataracts can creep in silently and cause permanent damage,” Dr Rimpika Mahajan, Senior Consultant, Sharp Sight Eye Hospitals, tells Moneycontrol. “In many cases, by the time patients notice changes in vision, the damage has already been done. So, don’t wait for symptoms to start seeing the problem,” she says.

Additionally, high blood sugar affects the small blood vessels in the retina. “Slowly, this can lead to swelling, bleeding or scarring, all of which can threaten sight if not caught early.” Dr Mahajan warns.
Healthy diet habits
Thankfully, much of the damage can be prevented, and it starts with the food you eat. “Eating a balanced diet rich in green leafy vegetables, fresh fruits, whole grains and lean proteins helps to regulate blood sugar and reduce stress on the eyes,” she says.
Cutting back on sugary treats and processed snacks is the best thing you can do to your health. “Avoiding those mid-day fried munchies or sweetened drinks can make a big difference. Stable sugar levels protect the delicate vessels in the eyes from long-term harm,” Dr Mahajan explains. Even small changes, like swapping packaged fruit juice for fresh fruit, can support blood sugar control and overall eye health.
Walk, rest, and get your eyes checked:
Fixing your food habits alone won’t help. Regular physical activity, even a 30-minute walk each day, can greatly help in managing diabetes. “Exercise improves blood flow, reduces insulin resistance and helps control weight. All these are protective for the eyes too,” Dr Mahajan informs.
She also recommends not ignoring regular eye checks. “The most common diabetic eye diseases have no early warning signs. An annual comprehensive eye exam is absolutely essential — even if you feel fine,” the expert says.

Other tips include staying hydrated, not smoking, and reducing screen time to give your eyes some much-needed rest. “Good habits today can mean clear vision for years to come. Prevention is not only possible, it’s powerful,” Dr Mahajan says.
