The types of myopia surgery include all-femtosecond laser surgery, semi-femtosecond laser surgery, surface laser surgery, and ICL (Implantable Collamer Lens) implantation. All-femtosecond laser surgery reshapes the corneal stroma using laser ablation to correct refractive errors and is suitable for individuals with mild to moderate myopia. Semi-femtosecond laser surgery combines femtosecond and excimer lasers, offering more precise ablation and broader applicability. Surface laser surgery acts directly on the corneal surface and is appropriate for patients with mild myopia and thinner corneas. ICL implantation involves inserting an artificial lens into the eye and is suitable for individuals with high myopia or corneal conditions unsuitable for laser surgery. Each method has its own characteristics, and the choice should be based on individual ocular conditions.

To ensure surgical safety and effectiveness, it is recommended to undergo comprehensive eye examinations first to understand corneal thickness, degree of myopia, and other ocular health conditions. Choosing a reputable hospital and experienced doctors for evaluation and procedure can greatly reduce risks. After surgery, it is essential to strictly follow postoperative care instructions, avoid rubbing the eyes or overusing them, and attend regular follow-up appointments to monitor recovery. As each person's ocular conditions differ, it is important not to blindly pursue a single surgical option but instead choose the most suitable procedure under professional guidance, ensuring the safety and effectiveness of vision correction.

Myopia patients can protect their eye health by consuming foods rich in nutrients such as vitamin A, lutein, and zinc. Vegetables like carrots, spinach, and kale contain abundant vitamin A and lutein, which can help improve retinal function and filter harmful blue light. Fish such as salmon and sardines are rich in omega-3 fatty acids, which help relieve dryness and eye fatigue. Nuts like walnuts and almonds provide zinc and vitamin E, which can enhance antioxidant capacity in the eyes and delay vision deterioration. In addition, egg yolks contain lutein and zeaxanthin, which also help protect vision.

To better protect the eyes, it is recommended to incorporate the above foods into daily meals and ensure balanced nutrient intake. Avoid consuming excessive high-sugar or fried foods, as these may accelerate the progression of myopia. Additionally, maintain good eye habits, such as taking a 5- to 10-minute break every 30 to 40 minutes of eye use, and increase outdoor activities to relax the eye muscles. Regular eye examinations are recommended to monitor vision changes and adjust dietary and eye-care practices according to medical advice.

Wearing colored contact lenses with a lower prescription than one's actual myopia degree may affect vision and eye health. If the difference in prescription is significant, it can cause blurry vision, increase the accommodative burden on the eyes, and potentially lead to visual fatigue, headaches, or eye discomfort such as soreness and swelling. Long-term use of improperly prescribed colored contact lenses may also worsen myopia or affect the normal function of the eye muscles. Additionally, an incorrect prescription may alter the cornea's refractive condition, further compromising visual quality.

To protect eye health, it is recommended to undergo professional refraction testing before purchasing colored contact lenses to ensure the selected product matches your degree of myopia. If discomfort or symptoms have already appeared, discontinue use immediately and consult an ophthalmologist for an eye examination. When wearing colored contact lenses daily, it's important to maintain hygiene and avoid prolonged continuous use—daily wear time should not exceed 8 hours. Regularly replacing and cleaning the colored contact lenses can reduce the risk of infection. Regular vision checkups and timely adjustments to corrective measures according to any changes will help maintain good eye health.

Myopia primarily develops when the eyeball is too long or the refractive system is abnormal, causing light to focus in front of the retina rather than directly on it. This condition is usually associated with the combined effects of genetic and environmental factors. If one or both parents have myopia, their children are at increased risk of developing it. Additionally, prolonged near-eye work, such as reading or using electronic devices, can cause the ciliary muscles of the eye to remain tense, gradually elongating the eye axis and ultimately leading to myopia. Poor eye-use habits, such as inadequate lighting or incorrect posture, can also accelerate the progression of myopia.

To prevent the onset of myopia, it is recommended to develop good eye-use habits and avoid prolonged near-eye work. Maintain proper sitting posture while studying, keeping a distance of 30 to 40 centimeters between the eyes and the book, and ensuring sufficient and soft ambient lighting. Schedule regular outdoor activities each day, as exposure to sunlight and focusing on distant objects can help relax the eye muscles and delay the onset of myopia. Reducing the amount of time spent using electronic devices, especially in dim lighting, can alleviate the burden on the eyes. Regularly monitoring changes in vision and taking timely interventions can effectively protect eye health.

Whether to wear glasses for 150-degree myopia usually depends on specific visual demands and daily life situations. For adolescents, 150 degrees is considered mild myopia. If distant objects appear blurry during class or daily activities, wearing glasses is recommended to help see clearly and avoid excessive eye strain caused by unclear vision. Long-term failure to wear glasses may accelerate the progression of myopia, especially in situations involving frequent visual effort, such as studying or sports. However, if blurry distance vision occurs only occasionally and good distance vision is not required most of the time, wearing glasses can be optional based on a doctor's advice.

To protect vision and slow the progression of myopia, it is recommended to undergo regular eye examinations to monitor vision changes and choose appropriate corrective methods under a doctor's guidance. It is also important to maintain healthy visual habits in daily life, such as taking a 5- to 10-minute break every 30 to 40 minutes of near work, and avoiding prolonged screen time or reading. Increasing outdoor activity time can also help relax eye muscles and reduce the risk of worsening myopia, as natural light and distance viewing are beneficial. Ensure that glasses are prescribed and fitted by a reputable facility to guarantee accurate lens prescriptions and prevent further damage caused by incorrect lens power.

Correcting myopia requires improving eye usage habits, wearing appropriate glasses, or adopting other methods. Maintaining correct reading and writing posture and reasonably managing eye usage time are fundamental steps. Increasing outdoor activities appropriately can relax the eye muscles and reduce accumulated fatigue. Furthermore, reducing prolonged near-eye work and increasing outdoor activity time can also help delay the progression of myopia to some extent. Wearing glasses or contact lenses with suitable prescriptions enables light to be properly focused on the retina, thereby improving vision. At the same time, regular vision examinations and adjusting the correction plan according to actual conditions are essential.

Start with daily care by ensuring sufficient lighting in the reading environment and maintaining an appropriate distance from screens, avoiding prolonged staring at electronic devices. Choose suitable eye exercises based on personal interests, such as eye movement exercises or focus-shifting drills between near and distant objects, to enhance accommodation ability. If glasses are required, opt for professional optometric services at reputable institutions and follow medical advice regarding their use. Additionally, maintaining a balanced diet enriched with nutrients like vitamin A helps maintain retinal health. Consistently following these measures over the long term can gradually improve vision and slow the progression of myopia.

Myopia primarily develops due to an elongated eyeball axis or abnormalities in the refractive system, causing light to focus in front of the retina rather than directly on it. This condition is closely related to both genetic and environmental factors. If one or both parents have myopia, their children are more likely to develop it as well. Additionally, prolonged near-eye work, such as reading or using electronic devices, can keep the eye's ciliary muscle continuously tense, gradually elongating the eyeball axis and ultimately leading to myopia. Poor visual habits, such as inadequate lighting, incorrect posture, or insufficient outdoor activity, can also accelerate the progression of myopia.

To prevent the onset of myopia, it is recommended to develop good eye habits and avoid prolonged near-eye work. Maintain correct sitting posture while studying, keeping a distance of 30 to 40 centimeters between the eyes and the book, and ensuring sufficient and soft ambient lighting. Schedule regular outdoor activities daily, as sunlight and viewing distant objects can help relax the eye muscles and delay the onset of myopia. Reducing the amount of time spent using electronic devices, especially in dim lighting, can alleviate eye strain. Regularly monitoring changes in vision and promptly implementing corrective measures can effectively protect eye health.

Conjunctivitis, medically known as red eye disease, is a common eye condition primarily characterized by symptoms such as redness of the eyes, increased secretions, foreign body sensation, and a feeling of burning. The recovery time varies depending on the cause and individual differences.

Generally, most patients can recover within one to two weeks with effective treatment. If the condition is severe or treatment is delayed, the recovery period may extend to two to three weeks, or even longer.

Bacterial conjunctivitis is caused by bacterial infections, such as Staphylococcus aureus, Streptococcus pneumoniae, etc. With appropriate treatment, symptoms can significantly improve within 3-5 days. However, it is essential to complete the full course of antibiotic treatment as prescribed by a physician to prevent recurrence and complications.

Allergic conjunctivitis is triggered by exposure to allergens such as pollen or dust mites. Symptoms can rapidly subside once the allergen is removed, but the condition tends to recur easily. Treatment includes the use of antihistamines, non-steroidal anti-inflammatory drugs, or topical corticosteroid eye drops, with the specific course determined according to the severity of the condition.

Patients should all maintain personal hygiene, avoid rubbing their eyes with their hands, and refrain from sharing items such as towels and pillows to prevent cross-infection.

Pinkeye, medically known as acute conjunctivitis, is a common eye condition primarily characterized by redness of the eye, increased discharge, and a foreign body sensation. The main transmission routes include direct contact transmission, droplet transmission, waterborne transmission, and iatrogenic transmission.

Direct contact transmission is the most common mode of transmission. When a patient's hands or personal items (such as towels or pillows) come into contact with their infected eyes and then subsequently touch the eyes of a healthy person, the pathogen can be transmitted to the healthy individual.

Airborne droplet transmission is another method of spread. Droplets released when an infected person coughs, sneezes, or speaks may contain pathogens, which others may inhale and become infected. Pinkeye can also spread through contaminated water sources and in healthcare settings.

In public water facilities such as swimming pools or hot springs, if the water becomes contaminated with discharge from a patient's eyes, other swimmers who come into contact with the water may also contract pinkeye. Therefore, it is important to avoid touching the eyes with hands before and after swimming in public places, and to wear goggles as much as possible to reduce the risk of infection.

If symptoms of pinkeye occur, prompt medical attention should be sought, and self-medication should be avoided to prevent delays in treatment.

Double eyelid surgery is a common cosmetic procedure aimed at creating a crease in the upper eyelid through surgical means to improve the appearance of the eyes. It is important to keep the eyelid area clean after surgery to avoid infection.

When washing your face, be careful not to splash water onto the wound. If there is blood crust or discharge, gently wipe it with sterile saline or medical alcohol. During the first few weeks after surgery, avoid strenuous physical activity or heavy labor to prevent increased eye pressure and to facilitate proper wound healing.

The surgical site should be kept clean and dry, avoiding contact with water or cosmetics until the wound is completely healed. Be cautious when washing your face to avoid splashing water onto the eye area. When sleeping, try to keep your head elevated above the level of your heart by using additional pillows, which can help reduce eye swelling.

In the early postoperative period, your eyes may be sensitive to light. Wearing sunglasses when outdoors not only protects your eyes but also conceals the eye area while it is still healing. After surgery, you may take antibiotics as directed by your physician to prevent infection. Additionally, medications that reduce swelling, such as Melilotus officinalis extract tablets, may be used as appropriate.

To ensure optimal surgical results and a smooth recovery process, it is essential to follow the guidance of a qualified physician, maintain personal hygiene, and properly manage your daily routine.
