Eye problems

Hello, Doctor.
I am highly myopic and would like to ask a few questions.

1.
A few days ago, my vision became blurry, and when I closed my left eye, I found that my right eye was completely blurry as well.
It returned to normal after several seconds.
Should I seek medical attention for this?
2.
(1) Last night, when I turned off the lights and blinked, I saw a patch of blue light, but it disappeared when I made the room darker to test it.
(2) However, later when I made it even darker and blinked several times to test, I felt like there was a brief moment of darkness when I opened my eyes (since I was already in a dark place, could this be excessive worry or something abnormal?).
3.
Regarding the presence of black spots and distortion (wavy lines) in my central vision, do these need to be persistent and obvious? I often experience brief appearances of black spots and a very slight sensation of distortion when looking at things (possibly an illusion?), which makes me anxious.
I understand that regular check-ups are necessary, but I often worry about these minor issues (even if they are just suspected) and it troubles me.
Am I overreacting?
4.
Is it normal to experience the following situations? (1) A light appears and then disappears at the lower edge of my vision.
(2) My eyes blink 1-2 times (not vigorously).
(3) Black spots and flashes of light (white or colored) appear and then disappear.
(4) Sometimes, when I was a child, I could see double vision.
(5) A brief stabbing pain (not severe and not continuous).
Thank you for patiently reading my concerns.
Are some of these minor issues possibly not requiring medical attention? I really need your response.
Thank you!

Hello, 20-year-old student:
1.
A few days ago, I experienced blurred vision, and when I closed my left eye, I found that my right eye was completely blurry.
It recovered after several seconds.
Should I seek medical attention? It could be caused by fatigue leading to slower eye accommodation, or there may be a difference in prescription between the two eyes.
Resting should help.
However, if this persists, it would be advisable to get it checked.
2.
(1) Last night, when I blinked in the dark, I saw a flash of blue light, but when I turned off the lights completely to test it, it disappeared.
(2) Later, when I blinked several times in the dark to test again, I noticed a brief moment of darkness when I opened my eyes (could this be due to being in a dark place, or is it excessive worry or something abnormal?).
This is likely a normal physiological phenomenon.
3.
Are the black spots and distortions (wavy lines) in my central vision persistent and obvious? If it is macular degeneration, the central vision would be persistently and significantly dark or distorted.
I often experience brief appearances of black spots or a fleeting sensation of slight movement when looking at something (possibly an illusion?), which makes me anxious.
This is likely unrelated and could be similar to floaters.
I understand the importance of regular check-ups, but I often feel troubled by these minor visual disturbances (even if they are just suspected).
Am I being overly concerned? Worrying is normal, but your situation does not seem to warrant excessive concern.
4.
Is it normal to experience the following conditions? (1) A light appearing and disappearing at the lower edge of the eye.
(2) The eyes flashing once or twice (not intensely).
(3) Black spots or flashes of light (white or colored) appearing and disappearing.
These are likely related to floaters.
(4) As a child, I sometimes saw double images, which could be due to astigmatism or strabismus.
(5) A brief, non-intense stinging sensation (not persistent) can occur due to inflammation, allergies, foreign bodies, dryness, etc., but it should resolve quickly and is likely not a concern.

Online responses can only serve as a reference; it is necessary to seek medical attention at a healthcare facility if needed.
I hope to have the opportunity to assist you.

Dear Patient,
Thank you for your detailed inquiry regarding your eye health concerns. As someone with high myopia, it is essential to be vigilant about any changes in your vision, as they can indicate underlying issues that may require medical attention. Let's address your questions one by one.

1. Blurred Vision in One Eye: Experiencing temporary blurred vision in one eye, especially if it resolves after a few seconds, can be concerning. However, if this happens infrequently and resolves quickly, it may not be an immediate cause for alarm. That said, if you notice this occurring more frequently or if it is accompanied by other symptoms such as flashes of light, floaters, or a significant decrease in vision, it is advisable to seek medical attention. These could be signs of retinal detachment or other serious conditions.

2. Seeing Blue Light and Black Spots: The phenomenon of seeing a blue light when blinking in the dark can be related to the way your eyes adjust to low light conditions. However, if you experience black spots or flashes of light, especially if they are new or increasing in frequency, it is crucial to consult an eye care professional. These symptoms can sometimes indicate retinal issues, such as a tear or detachment.

3. Central Vision Disturbances: The presence of black shadows or distortions in your central vision is a symptom that should not be ignored. If these disturbances are persistent and noticeable, it is essential to have a comprehensive eye examination. While occasional fleeting shadows or distortions can occur, especially in individuals with high myopia, consistent or worsening symptoms warrant further investigation to rule out conditions like macular degeneration or retinal problems.

4. Normal Eye Sensations: Regarding your other symptoms, such as transient flashes of light, brief black spots, or mild discomfort, these can sometimes be benign, especially if they are infrequent and not accompanied by other significant changes in vision. However, if you find these occurrences increasing in frequency or severity, it is wise to consult with an eye specialist.
In summary, while some of the symptoms you describe may not require immediate medical attention, it is essential to remain vigilant. Regular eye exams are crucial, especially for individuals with high myopia, as they can help detect potential issues early on. If you experience any sudden changes in your vision, such as a significant increase in floaters, flashes of light, or a curtain-like shadow over your vision, seek medical attention promptly.

It is understandable to feel anxious about your eye health, especially with the complexities of high myopia. However, maintaining regular check-ups and being proactive about any changes in your vision can help alleviate some of that anxiety. Always trust your instincts—if something feels off, it’s best to get it checked out.

Thank you for reaching out, and I hope this information helps clarify your concerns. Please do not hesitate to seek professional advice for any persistent or troubling symptoms.

Best regards,
