I. Introduction

In modern society, there is a growing focus on eye health issues, especially with the advancement of science and technology, such as the prolonged use of electronic devices, which increases the strain on the eyes. As a renowned ophthalmologist in Hong Kong, he has over 20 years of clinical experience, focusing on diagnosing and treating various ophthalmic diseases. He graduated from the Faculty of Medicine of the University of Hong Kong and has accumulated extensive academic and practical experience in international ophthalmology institutions. It is emphasized that the eyes are a window to the soul, and protecting your eyesight is not only the key to quality of life, but also to prevent serious diseases.

2. Detailed explanation of common eye diseases

1. Myopia

Myopia is one of the most common eye problems in Hong Kong, and according to statistics from the Hong Kong Health Bureau, about 60% of primary and secondary school students suffer from myopia. Dr. Ao Zhangzhong pointed out that the causes of myopia include genetic factors, prolonged use of closed eyes, and lack of outdoor activities. He suggested that parents should encourage their children to go outdoors for at least 2 hours a day and have regular eye exams. For patients who already have myopia, Dr. Ao Zhangzhong recommends the use of orthokeratology lenses (OK lenses) or low-concentration atropine eye drops to control the increase in myopia.

2. Dry eye syndrome

Dry eye syndrome is a common disease in modern civilization, especially in people who use computers and mobile phones for long periods of time. Dr. Ao Zhangzhong explained that the symptoms of dry eye syndrome include dry eyes, burning, blurred vision, etc., and in severe cases, they can even affect daily life. He suggested that patients can improve their symptoms by:

• Take regular breaks and close your eyes every 30 minutes or look into the distance
• Use artificial tears to keep your eyes moist
• Avoid spending too much time in an air-conditioned environment

3. Glaucoma

Glaucoma is known as the "thief of vision" and is often overlooked because its initial symptoms are not obvious. Dr. Ao Zhangzhong reminded that people over 40 years old, with a family history of medical history or high myopia are in the high-risk group. He emphasized that regular examination of intraocular pressure and optic nerve is key to early detection of glaucoma. According to the Hong Kong Glaucoma Association, about 3% of the population over the age of 40 suffer from glaucoma, but half of them are unaware of it.

4. Cataracts

Cataracts are a common eye disease in the elderly, primarily caused by aging of the lens. Dr. Ao Zhangzhong said that with the advancement of medical technology, cataract surgery is very mature, and patients do not need to wait until they are completely blind to undergo surgery. He suggested that surgery should be considered if vision affects daily life. According to statistics from the Hong Kong Hospital Authority, about 15,000 cataract surgeries are performed every year, with a success rate of over 95%.

3. Dr. Ao Zhangzhong's Eye Protection Advice

Dr. Ao Zhangzhong offers the following eye care tips to help people maintain good vision health:

• Maintain a balanced diet and consume foods rich in vitamins A, C, and E, such as carrots and blueberries
• Avoid using electronic devices continuously for long periods of time and follow the "20-20-20" principle (look at an object 20 feet away for 20 seconds every 20 minutes)
• Choose the right glasses or contact lenses and replace them regularly to ensure your vision is corrected

4. summary

Eye health is an important part of overall health, and Dr. Ao Zhangzhong once again called on the public to pay attention to eye examinations, especially high-risk groups, so that they need to undergo a comprehensive examination once a year. With early detection and proper treatment, most eye diseases can be effectively controlled. Start today by adopting eye protection habits and safeguarding this precious window to your soul.敖章鐘醫生
