Hello! Thank you for reaching out with your concerns about your eye health. Given your history of high myopia (nearsightedness) and the symptoms you are experiencing, it's important to take your situation seriously.
Firstly, the symptoms you describe—seeing flashes of light when transitioning from bright to dark environments, experiencing eye strain, and feeling discomfort, especially at night—could indicate a few potential issues. High myopia can lead to various complications, including retinal problems, which may manifest as flashes of light or floaters. These symptoms can be concerning, especially if they are new or have changed in intensity.
The fact that you notice these symptoms more when wearing contact lenses rather than glasses could suggest that your lenses may not be fitting properly or that they are not providing the necessary correction for your vision needs. Contact lenses can sometimes cause dryness or discomfort, particularly in low-light conditions, which might explain your symptoms of eye strain and discomfort.
It's also worth noting that the sensation of light sensitivity (photophobia) can occur for several reasons, including dry eyes, inflammation, or even issues related to the cornea or retina. Given your high degree of myopia and the associated risks, it is advisable to seek an eye examination sooner rather than later, even if you plan to return to Taiwan next month. While it may be tempting to wait, some conditions can worsen over time, and early intervention is often key to preventing more serious complications.

Regarding your question about flying after potential retinal issues or laser surgery, the general recommendation is to avoid flying for at least a week after any eye surgery, including laser procedures, to allow for proper healing. However, if you are experiencing retinal problems, it is crucial to have a thorough evaluation by an eye care professional. They can provide specific guidance based on your condition and any necessary treatments.

In the meantime, here are some tips to help manage your symptoms:
1. Limit Contact Lens Wear: If you are experiencing discomfort, consider reducing the amount of time you wear your contact lenses, especially in low-light conditions. Switch to glasses when possible.

2. Use Artificial Tears: If dryness is an issue, using preservative-free artificial tears can help alleviate discomfort and keep your eyes lubricated.

3. Take Breaks: If you are using screens or reading for extended periods, practice the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds to reduce eye strain.

4. Adjust Lighting: Ensure that your environment is well-lit, especially when transitioning from bright to dark areas. This can help reduce the strain on your eyes.

5. Monitor Symptoms: Keep track of any changes in your symptoms, such as increased frequency of flashes or floaters, and seek medical attention if they worsen.

In conclusion, while it may be tempting to wait until you return to Taiwan to see an eye doctor, I strongly encourage you to seek care as soon as possible, especially given your high myopia and the new symptoms you are experiencing. Your eye health is paramount, and early evaluation can help ensure that any potential issues are addressed promptly. Safe travels, and take care of your eyes!
