Blurred vision


Hello, Doctor.
When I read, I sometimes gently close my eyes or keep them closed for a longer time, and my vision becomes blurry.
Occasionally, when I focus on one spot for about 5 to 6 seconds, my vision also gets blurry, but after closing my eyes again, my vision returns to normal.
I visited a doctor, and they said my lens and cornea are normal, but it seems I have early presbyopia.
I would like to ask the doctor: 1.
I used to stay up late and overuse my eyes; is it true that I am experiencing early presbyopia? 2.
My vision is -6.50 in the left eye and -6.25 in the right eye; is this considered high myopia? My glasses prescription exceeds my myopia level, and the doctor said they are for distance vision.
I've been using these glasses for four years, but recently, when studying or reading up close, I often feel dryness and discomfort in my eyes.
Could this harm my eyes? I would appreciate any advice from the doctor.
Thank you!

Hello,
1.
The phenomenon similar to presbyopia can be restored with rest.

2.
A vision of 650 in the left eye and 625 in the right eye indicates high myopia.
Glasses with a prescription exceeding the degree of myopia are certainly not suitable.

Wishing you peace, health, and well-being.

Sincerely,
Dr.
Cai Wenyuan, Director of the Ophthalmology Department, Taoyuan Hospital, Ministry of Health and Welfare.

Hello! Thank you for your questions regarding your eye health. It’s great that you are being proactive about your vision and seeking information. Let’s break down your concerns and provide some insights based on current medical knowledge.

1. Blurry Vision and Eye Strain: The symptoms you describe, such as temporary blurry vision after closing your eyes or focusing on a point for a few seconds, can often be attributed to eye strain or fatigue. This is particularly common among individuals who spend extended periods reading or using screens without taking breaks. The phenomenon you’re experiencing could be related to a condition known as "accommodative spasm," where the eye's focusing muscles become fatigued, leading to temporary blurriness.
2. Early Presbyopia: Your mention of "young presbyopia" is interesting. Presbyopia typically occurs as part of the natural aging process, usually starting in the early to mid-40s, but it can manifest earlier in individuals who have a history of significant eye strain or prolonged near work. If you’ve been staying up late and overusing your eyes, it could indeed contribute to symptoms that mimic presbyopia.

3. High Myopia: With your prescription of -6.50 in the left eye and -6.25 in the right, you are classified as having high myopia. This level of nearsightedness can lead to various complications, including an increased risk for retinal detachment and other eye health issues. It’s important to have regular eye exams to monitor your eye health, especially given your degree of myopia.

4. Eyewear Prescription: You mentioned that your glasses prescription is higher than your current myopia. This is not uncommon, as prescriptions can be adjusted based on your visual needs, especially for distance vision. However, if you are experiencing discomfort or dryness while wearing your glasses, it might be worth revisiting your eye care provider to ensure your prescription is still appropriate for your current needs.

5. Dry Eyes: The sensation of dryness you’re experiencing could be linked to several factors, including prolonged screen time, inadequate blinking, or even the environment (like air conditioning or heating). Dry eyes can lead to discomfort and may contribute to blurry vision. To alleviate this, consider the following:
- Take Regular Breaks: Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.

- Stay Hydrated: Drink plenty of water to help maintain moisture levels in your body.

- Use Artificial Tears: Over-the-counter lubricating eye drops can help relieve dryness.

- Adjust Your Environment: Use a humidifier if you’re in a dry environment, and try to avoid direct airflow from fans or air conditioning on your face.

6. Long-term Eye Health: To protect your eyes, especially given your high myopia and symptoms of dryness, consider incorporating eye health supplements like lutein and zeaxanthin, which are known to support retinal health. Regular eye exams are crucial for monitoring any changes in your vision and overall eye health.

In summary, while your symptoms may be concerning, they are not uncommon among individuals who engage in significant near work or have high myopia. Regular check-ups with your eye care provider, proper eyewear, and good eye care habits can help manage your symptoms and maintain your eye health. If your symptoms persist or worsen, be sure to seek further evaluation from an eye care professional.
