Eye Fatigue: Symptoms and Solutions for High Myopia - Ophthalmology

More Info

---

Understanding eye fatigue, especially in the context of high myopia, is crucial for maintaining eye health and comfort. High myopia, defined as a refractive error greater than -6.00 diopters, can lead to various ocular symptoms and complications. Your experience of discomfort, headaches, and visual disturbances, particularly when viewing bright lights, is not uncommon among individuals with high myopia.


Symptoms of Eye Fatigue
1. Visual Disturbances: As you mentioned, seeing halos or rainbow-like rings around lights, especially at night, is often associated with corneal irregularities or changes in the eye's optics. This phenomenon can be exacerbated by dry eyes, which you noted as a concern. The use of contact lenses, particularly if worn for extended periods, can contribute to dryness and discomfort.

2. Headaches: The pain you experienced in your left temple could be tension-related, often stemming from prolonged near work or eye strain. This is particularly relevant for individuals with high myopia, as they may unconsciously strain their eyes to focus better.

3. Dryness and Fatigue: High myopia can lead to a higher incidence of dry eye syndrome, especially if you spend significant time on screens or reading. Symptoms include a gritty sensation, burning, or a feeling of heaviness in the eyes.


Causes of Eye Fatigue
- Prolonged Near Work: Engaging in activities that require intense focus, such as reading or using digital devices, can lead to eye fatigue. The ciliary muscle, which controls the lens's shape for focusing, can become fatigued from constant accommodation.

- Environmental Factors: Dry air, prolonged screen time, and inadequate lighting can exacerbate symptoms of eye fatigue.
- Contact Lens Use: While contact lenses can provide convenience, they may also lead to dryness and discomfort if not properly managed. It's essential to follow the recommended wearing schedule and ensure proper hygiene.


Solutions and Management
1. Artificial Tears: The use of artificial tears, as prescribed by your doctor, can help alleviate dryness and provide comfort. It's advisable to use preservative-free options, especially if you wear contact lenses.

2. Regular Breaks: Implementing the 20-20-20 rule can be beneficial. Every 20 minutes, take a 20-second break to look at something 20 feet away. This practice helps reduce eye strain.

3. Proper Lighting: Ensure that your workspace is well-lit to minimize glare and strain on your eyes. Avoid working in dim lighting, especially when using screens.

4. Contact Lens Care: If you choose to wear contact lenses, ensure they are the right fit and type for your eyes. Consider daily disposables if dryness is a significant issue, as they can reduce the risk of irritation.

5. Regular Eye Exams: Regular check-ups with your eye care professional are essential, especially for those with high myopia. They can monitor for any changes in your vision or eye health and adjust your treatment plan as necessary.

6. Consider Glasses for Extended Use: If you find that your eyes are particularly fatigued after wearing contact lenses, consider switching to glasses for prolonged use, especially during activities that require significant focus.


Conclusion
Your symptoms of eye fatigue and visual disturbances are common among individuals with high myopia, particularly when engaging in prolonged near work or using contact lenses. By implementing proper eye care practices, utilizing artificial tears, and ensuring regular eye examinations, you can manage these symptoms effectively. If your symptoms persist or worsen, it is crucial to follow up with your eye care provider for further evaluation and management.
