Eye Floaters and Visual Disturbances While Watching TV - Ophthalmology

Hello! Thank you for reaching out with your concerns regarding eye floaters and visual disturbances, especially while watching TV. It sounds like you've been experiencing a range of symptoms, including seeing transparent black dots (floaters) and occasional flashes of light. Let's break down these issues and provide some clarity.


Understanding Eye Floaters
Eye floaters are small specks or strands that drift through your field of vision. They are typically caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can become more liquid and may pull away from the retina, leading to the perception of floaters. This is a common condition and is often benign, especially if there are no accompanying symptoms like flashes of light or significant changes in vision.

In your case, since your doctor has already examined your eyes and confirmed that there are no retinal tears or other serious issues, it is likely that what you are experiencing is indeed floaters. These can be more noticeable against bright backgrounds, such as when you are looking at a white screen or a bright sky.


Visual Disturbances While Watching TV
Regarding the visual disturbances you mentioned while watching TV, such as seeing a line or flicker on the screen, this could be attributed to several factors:
1. Screen Refresh Rate: Sometimes, the refresh rate of the TV or the connection can cause flickering or lines to appear, especially if there is a poor signal or if the settings are not optimized.

2. Visual Perception: If you are experiencing floaters, they may become more noticeable when you are focused on a bright screen. The contrast can make them seem more prominent.

3. Flashes of Light: The term "flashes" that your doctor referred to typically describes a phenomenon where you see brief bursts of light in your peripheral vision. This can occur if the vitreous is tugging on the retina. If you experience this frequently or if it is accompanied by a sudden increase in floaters, it is essential to seek medical attention.


Should You Be Concerned?
Given that you have already had a thorough examination and your doctor has reassured you, it may not be necessary to return immediately unless you experience new symptoms, such as:
- A sudden increase in the number of floaters.

- The appearance of flashes of light that are persistent or frequent.

- A shadow or curtain effect in your vision.

If you notice any of these changes, it would be wise to consult your eye care professional promptly.


Can Floaters Disappear?
As for whether floaters can disappear, the answer varies from person to person. Some individuals may find that their floaters become less noticeable over time as the brain learns to ignore them. In some cases, floaters may persist or even increase in number, particularly as one ages. However, they are generally harmless unless they are associated with more serious eye conditions.


Conclusion
In summary, while your symptoms of floaters and occasional visual disturbances can be concerning, they are often benign, especially if you have been evaluated by an eye care professional. Keep monitoring your symptoms, and if you notice any significant changes, do not hesitate to seek further evaluation. In the meantime, ensure that your screen settings are optimized and take regular breaks when watching TV or using digital devices to reduce eye strain. Thank you for your inquiry, and I hope this information helps alleviate some of your concerns!
