Which lifestyle choice can negatively impact eye health?

Smoking is a lifestyle choice that can significantly harm eye health due to its harmful effects on the body's overall well-being and specifically the eyes. Research indicates that smoking is linked to an increased risk of developing serious eye conditions, including cataracts, age-related macular degeneration, and other vision-threatening ailments. The toxic substances in cigarette smoke can damage the optic nerve and decrease blood flow to the eyes, leading to a variety of vision problems.

In contrast, regular exercise, a balanced diet, and staying hydrated are all beneficial lifestyle choices that help maintain good eye health. Regular exercise promotes overall cardiovascular health, which improves blood circulation, including to the eyes. A balanced diet rich in vitamins and minerals, particularly those that support vision like vitamin A, C, and E, can contribute to better eye health. Staying hydrated is essential as well, as it helps maintain the moisture needed for the eyes to function properly and can prevent discomfort and dryness.
