Understanding eye floaters can be quite complex, especially when considering the various symptoms and experiences individuals may have. Let's break down your questions and concerns regarding floaters, flashes, and overall eye health.

1. What are the "cloudy spots" you see when looking at bright light?
The phenomenon you describe, where you see circular, cloudy spots when looking at bright light, could indeed be related to floaters or possibly flashes of light. Floaters are tiny clumps of gel or cells that form in the vitreous, the clear gel-like substance that fills the eye. When light hits these clumps, they cast shadows on the retina, which is perceived as floaters. Flashes, on the other hand, occur when the vitreous gel pulls on the retina, causing it to send signals to the brain that are interpreted as light. If these symptoms are new or have changed significantly, it's essential to consult an eye care professional to rule out any serious conditions, such as retinal tears or detachments.

2. Is it concerning to have floaters since the age of 15?
Having floaters, especially if they have been present for many years, is generally not a cause for concern. Many people experience floaters as they age, and they are often benign. However, if there is a sudden increase in the number of floaters, or if they are accompanied by flashes of light or a shadow in your peripheral vision, it is crucial to seek medical attention promptly. These could be signs of a more serious issue, such as a retinal tear or detachment.

3. Why do you see flashes when your eyes are closed?
Seeing flashes of light when your eyes are closed can be attributed to various factors. It could be related to the pressure on the eyes when they are closed, which can stimulate the retina. Additionally, if you have a history of floaters or retinal issues, your brain may still interpret certain stimuli as flashes. This is often benign, but if it occurs frequently or is accompanied by other symptoms, it would be wise to discuss it with your eye doctor.

4. Does excessive screen time affect floaters?
While using screens extensively does not directly cause floaters, it can lead to eye strain and fatigue, which may make you more aware of existing floaters. Prolonged screen time can also contribute to dry eyes, which can exacerbate discomfort and the perception of floaters. It’s essential to take regular breaks from screens, practice the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), and ensure proper lighting to reduce eye strain.

5. How can you reduce the impact of floaters on your vision?
Unfortunately, there is no guaranteed way to eliminate floaters, but there are several strategies to manage their impact on your vision:
- Stay Hydrated: Keeping your body well-hydrated can help maintain the health of the vitreous gel.

- Healthy Diet: Consuming a diet rich in antioxidants (found in fruits and vegetables) may support overall eye health.

- Regular Eye Exams: Regular check-ups with an eye care professional can help monitor any changes in your vision and address concerns promptly.

- Avoiding Eye Strain: As mentioned, taking breaks from screens and ensuring proper lighting can help reduce discomfort associated with floaters.

In summary, while floaters are often benign, any significant changes in your vision should be evaluated by an eye care professional. Maintaining good eye health through hydration, a balanced diet, and regular eye exams is essential. If you experience new symptoms or an increase in floaters, do not hesitate to seek medical advice.
