Visual Disturbances After Solar Eclipse Viewing

When looking at a white wall, I experience rippling flashes of light when my eyes move up and down?

Hello, Doctor: At the end of June 2020, during the annular solar eclipse (like a ring), I looked at the sun with the naked eye for about ten seconds.
After looking away, the visual afterimage of the sun lasted for about two minutes.
When I got home that day, I felt that my vision was a bit blurry, but there was no change in my prescription.
Later, at the end of July, I suddenly noticed a significant increase in floaters, and the computer screen appeared dirty, as if there were many black droplets, which prompted a dilated eye exam.
The doctor diagnosed me with floaters and mild cataracts, recommending a follow-up in six months.
I still see a lot of floaters that interfere with my ability to use the computer and read.
I would like to ask:
1.
When I look at a white wall and see rippling flashes, what is this phenomenon? Do I need to seek immediate medical attention? Can I continue exercising?
2.
Is the appearance of my floaters related to looking directly at the solar eclipse? My three-year-old child also looked at it with the naked eye for about five seconds; could this harm their eyes? Do they need to see a doctor?
3.
When I close my eyes or squeeze them tightly while sleeping, I see a bright ring similar to the solar eclipse; is this normal?
4.
Now, the visual afterimage seems to last longer.
When I stop my car, I inadvertently notice a visual afterimage of the crosswalk lasting about two to three seconds, leading me to think there is a painted crosswalk there.
Additionally, I sometimes experience visual afterimages that affect my ability to see clearly for a few seconds.
Is this normal? Thank you for your patient response, I appreciate it!

Hello,
1.
It is possible that the vitreous is pulling on the retina.
Therefore, it is advisable to avoid activities that may cause this phenomenon.
If you experience this condition while at rest, you should seek an examination promptly.

2.
It should not be related.
A few seconds of exposure is unlikely to cause significant harm and should be recoverable.

3.
This may be a physiological phenomenon known as photopsia.

4.
Prolonged visual persistence may be a physiological change and should not be a cause for concern.

It sounds like you've experienced a series of visual disturbances following your exposure to the sun during the solar eclipse. Let's address your concerns one by one, while also providing some context about the potential effects of looking directly at the sun.

1. Rippling or Flickering Lights: The phenomenon you're describing, where you see rippling or flickering lights when looking at a white wall, could be related to a few different factors. It might be a result of the afterimages from your previous exposure to bright light, or it could be a sign of retinal irritation or changes in the vitreous gel of your eye. If this symptom persists or worsens, it would be wise to consult an eye care professional to rule out any serious conditions.

2. Connection Between Solar Eclipse Viewing and Floaters: The appearance of floaters (the "black rain droplets" you mentioned) can be a common occurrence, especially as we age, due to changes in the vitreous humor of the eye. However, direct exposure to the sun can potentially exacerbate or accelerate these changes, leading to an increase in floaters. As for your three-year-old child, any direct viewing of the sun, even for a few seconds, can be harmful. It is advisable to have them evaluated by an eye specialist to ensure there are no lasting effects.

3. Seeing Bright Rings When Closing Your Eyes: The bright rings you see when you close your eyes or press on them can be a normal phenomenon known as "phosphene." This occurs due to pressure on the retina or the stimulation of the optic nerve. However, if these experiences become frequent or are accompanied by other symptoms, it would be prudent to seek medical advice.

4. Visual Residuals and Afterimages: The prolonged afterimages you are experiencing, such as seeing a zebra crossing after looking away, can be a normal response to bright light exposure. However, if these afterimages are becoming more pronounced or are affecting your daily life, it would be beneficial to consult with an eye care professional. They can perform a thorough examination to determine if there are any underlying issues that need to be addressed.

In summary, while some of the symptoms you are experiencing can be attributed to normal physiological responses to bright light exposure, it is essential to monitor these symptoms closely. If you notice any changes in your vision, increased frequency of symptoms, or if they interfere with your daily activities, seeking a comprehensive eye examination is advisable.
Additionally, it’s important to educate yourself and others about the dangers of looking directly at the sun, even during events like solar eclipses. The damage caused by direct sunlight can lead to conditions such as solar retinopathy, which can have long-lasting effects on vision. Protecting your eyes with appropriate solar viewing glasses is crucial during such events.

In conclusion, while some of your experiences may be normal, it’s always best to err on the side of caution when it comes to eye health. Regular check-ups with an eye care professional can help ensure that any potential issues are caught early and managed appropriately.
