Methods for Preventing Fundus Diseases 1. Children and young adults should ideally undergo a fundus examination every six months, while the elderly and individuals with "three highs" (hypertension, hyperlipidemia, and hyperglycemia) should have check-ups every three months. This is a crucial aspect of preventing fundus diseases. Before the elderly undergo a fundus examination, it is advisable to first have an intraocular pressure test. This is because a comprehensive and detailed fundus examination sometimes requires pupil dilation, which is not suitable for elderly individuals with high intraocular pressure or a tendency toward glaucoma. 2. Fundus examination is not only an essential method for detecting diseases of the vitreous body, retina, choroid, and optic nerve but also serves as a "window" for monitoring many systemic diseases. This is an excellent approach to preventing fundus diseases. 3. To prevent fundus diseases, it is also important to minimize or avoid high-calorie foods such as sugary snacks, sweetened beverages, and fried foods. Additionally, reduce the intake of salt-preserved foods like pickles and animal fats. Daily Prevention of Fundus Lesions If you naturally have low tear secretion and are prone to dry eyes, it is not advisable to wear contact lenses while using a computer; opt for glasses instead. For those who wear contact lenses in front of a computer, it is best to choose varieties with high oxygen permeability. This is one of the methods for preventing fundus lesions. Preventing fundus lesions requires maintaining a good working posture. Adopt a comfortable posture where your eyes are level or slightly downward when looking at the screen. This relaxes the neck muscles and minimizes the exposure of the eyeballs to the air. Adjust the distance and position of the screen. It is recommended to keep a distance of 50-70 centimeters, with the screen positioned 10-20 centimeters below eye level at a downward angle of 15-20 degrees. This angle and distance help reduce the demand for refractive power and lower the likelihood of eye fatigue. Take regular breaks and avoid overusing your eyes. Preventing fundus lesions also involves avoiding the development of myopia. Refrain from staring fixedly and make a conscious effort to blink frequently and completely. Frequent blinking reduces the time your eyes are exposed to the air and prevents tear evaporation. A Balanced Diet for Preventing Fundus Diseases Prolonged screen time can lead to excessive consumption of photosensitive substances in the retina. If vitamin A and related nutrients are not replenished in a timely manner, it may result in symptoms of fundus diseases such as eye pain, blurred vision, and photophobia, and may even induce night blindness. Fresh cherries contain 4-5 times more vitamin A per 100 grams compared to fruits like apples and grapes. Cherries also have the highest iron content among fruits, and iron is a key component of hemoglobin, making them particularly suitable for women affected by computer radiation. Consume foods beneficial for vision, such as longan flesh, Chinese yam, carrots, spinach, sweet potatoes, taro, corn, animal liver, beef, mulberries, and red dates. Alternatively, brewing tea with red dates, ginseng, goji berries, chrysanthemums, or monk fruit can also help protect the eyes and prevent fundus diseases.
