Introduction

Lutein does not directly treat myopia, but it can help prevent the onset of myopia and slow down the progression of refractive error, especially benefiting adolescents and individuals with prolonged eye use. Myopia that has already developed cannot be reversed by supplementing lutein and requires scientifically-based corrective methods. Lutein can be obtained through daily diet by consuming more dark green or orange-yellow foods such as spinach, kale, and corn.

Lutein does not directly treat myopia, but it can help prevent the onset of myopia and slow down the progression of refractive error, especially benefiting adolescents and individuals who spend long hours using their eyes. Once myopia has developed, lutein supplementation cannot reverse it; scientific corrective methods are still required. Detailed analysis is as follows:

Lutein is a key nutrient in the macular region of the retina. It filters harmful blue light from electronic screens and strong lighting, reducing retinal photodamage and relieving symptoms of eye fatigue such as dryness and soreness. During adolescence, when visual development is ongoing, lutein supplementation strengthens the eye's resistance to damage. Combined with good visual habits, this can lower the risk of developing myopia. For individuals who already have myopia, taking lutein may reduce further progression caused by eye strain and provide fundamental ocular protection. However, since lutein cannot alter axial length of the eye or corneal refractive power, it cannot cure existing myopia and should not replace corrective methods such as eyeglasses or orthokeratology lenses.

Lutein can be obtained through daily diet by consuming more dark green or orange-yellow foods such as spinach, kale, and corn. When using electronic devices for extended periods, apply the 20-20-20 rule to reduce eye fatigue: every 20 minutes, look at something 20 feet away for 20 seconds.

Where is the corpus luteum located?

The macula forms a pale yellow area in the center of the retina, approximately 1 to 3 millimeters in diameter. Its distinctive color results from a high concentration of lutein, clearly distinguishing it from the surrounding retinal tissue. This region contains a large number of photoreceptor cells, particularly cone cells responsible for fine vision. The dense packing of these cells makes the macula the central area for visual signal reception.

What should you eat if you have cataracts?

A balanced diet is important in daily life. People with cataracts can generally consume foods such as spinach, oranges, nuts, oysters, and carrots. Spinach is rich in lutein, which can accumulate in the lens and help filter harmful light, reducing light-induced damage to the lens and slowing the progression of cataracts. Spinach can be eaten regularly with staple foods or prepared as a vegetable salad.

What causes the eyes to be too tired to open?

In general, difficulty opening the eyes and feeling fatigued may be caused by lack of sleep, excessive eye strain, visual fatigue, dry eye syndrome, hypothyroidism, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. In daily life, consume more foods rich in vitamin A and lutein, such as carrots, blueberries, and egg yolks.

Why do my eyes feel very tired and constantly fatigued?

In general, eye fatigue and a constant feeling of tiredness may be caused by lack of sleep, excessive eye use, visual strain, dry eye syndrome, refractive errors, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. In daily life, consume more foods rich in vitamin A and lutein, such as carrots and blueberries, and avoid rubbing your eyes with your hands.
