A recent survey has found that climate change and increasing dependence on processed store-bought foods are contributing to a rise in cataracts across Vanuatu.

Eye Coordinator at Vila Central Hospital, Danstan Tate, says there has been an 80% increase in cataract cases among people aged 55 and above, compared to previous years.

“A survey that was carried out in 2023 covering all six provinces—from Torba to Tafea—looked at 5,600 people. The top cause of vision loss was cataracts, followed by non-communicable diseases (NCDs),” Tate explained. “Cataracts develop due to strong sunlight and not wearing sunglasses. The eye tries to protect itself, which leads to cataract formation. NCDs are also a major factor—they affect the blood and lead to blindness.”

Cataracts form when the eye develops a cloudy or white patch, resulting in blurred vision or eventual blindness.

Tate emphasized the importance of daily sun protection, especially for young people:
“Everyone should wear sunglasses every day. Cataracts can develop in both eyes and worsen with time. People that live with Cataracts for 15 or 16 can still be more affected. Use sunglasses, umbrellas, or hats—while they don’t block the sun completely, sunglasses reduce the amount of sunlight hitting the eyes.”

He also urged the public to cut back on store-bought foods to prevent diet-related eye complications.

“NCDs are rising. We have to control it because they lead to complications in the eye. Always eat the right foods. Avoid eating too much processed food from shops and always exercise.”
