Flashes of light when moving the eyes?
Hello doctor, this morning I noticed that when I quickly move my left eye (looking quickly to the left or right), I see flashes of light and a significant number of black lines floating, similar to floaters.
Should I seek medical attention for this? There is no noticeable change when I focus on the TV or my phone; the flashes and floaters only appear during rapid movements.

More Info
Flashes and floaters in vision can be concerning symptoms, especially when they appear suddenly or change in frequency or intensity. Based on your description, it seems that you are experiencing flashes of light and a significant number of floaters, particularly when you move your eyes quickly. This situation warrants careful consideration and possibly immediate medical attention.
Understanding Flashes and Floaters
Flashes are often caused by the vitreous gel inside the eye pulling on the retina, which can happen as the vitreous shrinks with age or due to other factors. This pulling can create the sensation of light flashes, which may appear as streaks or spots of light in your vision. Floaters, on the other hand, are tiny clumps of gel or cells that float in the vitreous and cast shadows on the retina, appearing as small dots or lines in your field of vision.
When to Seek Eye Care
1. New Onset of Symptoms: If you have recently started experiencing these symptoms, especially if they are new or have changed in nature, it is crucial to seek an eye care professional's opinion. Sudden changes can indicate potential issues such as retinal tears or detachments.
2. Increased Frequency or Intensity: If you notice that the flashes or floaters are becoming more frequent or intense, this could be a sign of a more serious condition.
3. Associated Symptoms: Pay attention to any other symptoms that may accompany the flashes and floaters, such as:
- A sudden increase in the number of floaters.
- A shadow or curtain effect in your peripheral vision.
- Blurred vision or loss of vision.
4. Eye Movement Triggers: Since you mentioned that the flashes occur specifically with quick eye movements, this could indicate that the vitreous is pulling on the retina. This is particularly concerning if it is accompanied by a significant number of floaters.
Recommended Actions
Given your symptoms, it is advisable to schedule an appointment with an eye care professional as soon as possible. They may perform a comprehensive eye examination, including a dilated fundus examination, to assess the health of your retina and vitreous.
Possible Outcomes
- Normal Aging Changes: In many cases, flashes and floaters are benign and related to normal aging changes in the eye. However, it is essential to rule out any serious conditions.
- Retinal Tear or Detachment: If a tear or detachment is found, timely intervention is crucial to prevent permanent vision loss. Treatments may include laser therapy or surgical options, depending on the severity.
- Monitoring: If the examination reveals no immediate concerns, your eye doctor may recommend regular monitoring of your symptoms, advising you to return if they worsen.
Conclusion
In summary, while flashes and floaters can often be benign, your specific symptoms, particularly their new onset and the fact that they occur with rapid eye movements, suggest that you should seek eye care promptly. Early detection and treatment are vital in preserving your vision and addressing any potential issues effectively. Remember, it’s always better to err on the side of caution when it comes to eye health.
