Floaters and Eye Health: Concerns for Myopic Patients

Floaters and Eye Diseases

1.
Hello, doctor.
Thank you for your response.
I am 22 years old, and my eyesight is approximately -7.00 diopters in both eyes.
I developed floaters five years ago, and a few years back, an eye doctor examined my fundus and mentioned signs of degenerative changes due to high myopia.
However, subsequent eye exams indicated that everything was fine.
During high school, I had periods of poor eating habits, sometimes only consuming instant noodles.
Could my floaters be related to this, or are they a consequence of the degenerative changes associated with high myopia? Since I have floaters, does that mean my eyes are less healthy and require more protection? Does the quantity of floaters have any significance? I feel like I see quite a few dark spots.
2.
Does bending over, tilting my head, shaking my head, or engaging in vigorous exercise increase the risk of developing eye diseases? I am afraid of going blind, but these movements are unavoidable in daily life.
Additionally, I want to engage in physical training and weightlifting.
I enjoy running marathons and playing badminton, and I also need to carry heavy gear while hiking.
However, I am cautious about bending, turning my head, shaking, and vigorous activities, which makes me hesitant to give my all and feels restrictive.
I know that during military training, I will have to perform these physical activities.
3.
If I stretch vigorously, take deep breaths, occasionally stay up late, and have a history of running, constipation, and smoking, how might this affect my eyes? I also tend to cough, sneeze, and blow my nose when I have a cold, which are hard to avoid.
4.
I briefly asked my current eye doctor about my concerns, and he mentioned that I am still young and should avoid jumping and diving.
However, the information I found online aligns with what the doctor said.
There are various opinions on the causes and probabilities of eye diseases related to high myopia.
I lack confidence in my eyes, and it affects my studies and daily life.
I worry that the more I engage in the activities mentioned above, the greater the risk of developing eye diseases.

Hello,
1.
Based on your description, your floaters are likely a consequence of myopia, specifically due to vitreous degeneration.
The quantity of floaters is not particularly significant, but if there is a sudden increase, an examination is necessary.

2.
The activities you mentioned are generally not concerning.
From what I know, activities such as weightlifting or free falling are more likely to have an impact.
I suggest you don't worry too much.
Regular retinal examinations are recommended, avoid rubbing your eyes, and seek medical attention promptly if you notice any abnormalities.

3.
These issues are also manageable.

4.
I still recommend maintaining a normal routine and not letting this distract you too much.

Dear Patient,
Thank you for reaching out with your concerns regarding floaters and your overall eye health, especially as a myopic individual. I understand that dealing with these issues can be quite stressful, particularly when you are young and active. Let’s address your questions and concerns in detail.

1. Understanding Floaters: Floaters are small specks or strands that drift through your field of vision. They are often caused by changes in the vitreous gel that fills the eye, which can become more liquid as we age. In your case, having high myopia (around -7.00 diopters) can increase the likelihood of experiencing floaters, as myopia is associated with changes in the structure of the eye, including the vitreous. While your previous doctor mentioned retinal degeneration, it is important to note that floaters themselves are generally harmless unless accompanied by flashes of light or a sudden increase in their number, which could indicate a retinal tear or detachment.
2. Impact of Lifestyle on Eye Health: Your concerns about bending, turning your head, or engaging in vigorous activities are common among those with myopia. While these actions can sometimes lead to increased awareness of floaters, they do not inherently increase the risk of developing eye diseases. It is crucial to maintain a balanced lifestyle, including physical activities like running or playing badminton, as these contribute positively to your overall health. However, if you experience any sudden changes in your vision during these activities, it would be wise to consult an eye care professional.

3. Daily Activities and Eye Strain: Activities such as stretching, coughing, or sneezing are normal and should not significantly impact your eye health. However, if you notice that certain actions seem to exacerbate your floaters or cause discomfort, it might be beneficial to discuss these symptoms with your eye doctor. They can provide personalized advice based on your specific condition.

4. Psychological Impact of Eye Health: It’s understandable to feel anxious about your eye health, especially with the information available online. The fear of losing vision can be overwhelming, but it’s important to remember that many people with high myopia live healthy lives without significant issues. Regular check-ups with an eye care professional can help monitor your condition and provide peace of mind. If your anxiety continues to affect your daily life, consider speaking with a mental health professional who can help you manage these feelings.

5. Protecting Your Eyes: To maintain your eye health, consider the following tips:
- Regular Eye Exams: Keep up with regular eye exams to monitor any changes in your vision and eye health.

- Healthy Diet: A balanced diet rich in antioxidants (like vitamins C and E, omega-3 fatty acids, and zinc) can support eye health.

- Hydration: Stay hydrated to help maintain the health of your eyes.

- Limit Screen Time: Take regular breaks from screens to reduce eye strain.

- Protective Eyewear: Use sunglasses that block UV rays when outdoors.

In conclusion, while floaters can be concerning, they are often a normal part of the aging process of the eye, especially in myopic individuals. Engaging in a healthy lifestyle, maintaining regular check-ups, and managing anxiety are key steps in ensuring your eye health remains stable. If you have any further questions or experience any changes in your vision, please do not hesitate to reach out to your eye care provider.

Wishing you good health and peace of mind.

Sincerely,
Doctor Q&A Teams
