Foods and practices that help improve vision include those rich in lutein, ingredients containing vitamin A, liver-nourishing and yin-tonifying traditional Chinese herbs, moderate eye exercises, and scientifically sound eye-use habits. These methods protect eyesight through nutritional supplementation or functional regulation and help alleviate eye discomfort. If symptoms such as persistent blurred vision, eye pain, or photophobia occur, it is recommended to seek medical attention promptly.
1. Foods rich in lutein: Lutein is a key component of the macular region of the retina. It is abundant in foods such as spinach, corn, and egg yolks. It helps filter blue light and reduce retinal damage. Long-term, moderate intake can support macular health and slow down vision deterioration.
2. Ingredients containing vitamin A: Vitamin A is essential for the photoreceptor cells in the retina. Foods like carrots, animal liver, and dairy products can supply this nutrient, improving dark adaptation, preventing night blindness, and relieving dry eyes and corneal dryness.
3. Yin-nourishing and liver-tonifying Chinese herbs: Herbs such as Lycium (goji berries), chrysanthemum, and cassia seeds have the effect of nourishing liver yin and clearing the liver to improve vision. They can be consumed as herbal teas or used in combination formulas to help relieve dizziness, blurred vision, and visual disturbances caused by yin deficiency of the liver and kidneys.
4. Moderate eye exercises: Performing daily eye exercises such as eye保健操 (eye health exercises), gazing into the distance, and rotating the eyeballs can promote ocular blood circulation, relax the ciliary muscle, relieve eye fatigue, and reduce damage to vision from prolonged near-work activities.
5. Scientific eye-use habits: Avoid prolonged screen time, maintain a viewing distance of 30–40 cm, take a 5–10 minute break every 40 minutes of eye use, and ensure adequate lighting. These practices help reduce eye strain and lower the risk of refractive errors.
In daily life, ensure sufficient sleep to allow the eyes full rest, avoid rubbing the eyes to prevent bacterial infections, spend more time outdoors exposed to natural light, and maintain a balanced diet without picky eating to provide comprehensive nutritional support for eye health.
