Is Your Eye Doctor's Advice Correct? Visual Symptoms

Is the doctor's advice correct?

I have noticed over the past couple of days that when I look at the computer or bright backgrounds, I feel something strange.
Everything is very clear, but it seems like there is a very faint, almost invisible shadow overlaying my vision, which is different from the small black dots associated with floaters.
It does not affect my daily life; generally, I see things very clearly, and there are no issues with bright objects on the road.
However, I feel a bit uncomfortable when looking at white backgrounds, but it does not interfere with my work.
I asked some foreign websites, and they suggested it might be computer vision syndrome.
I'm not sure if that's correct.
I have myopia in my left eye (-500) and right eye (-300), and I've been using my phone and computer quite a lot in the past few weeks, sometimes staying up late.
I wonder if this could be the cause.
Thank you!
Response from Dr.
Pi-Lin Kao, Ophthalmologist: Hello, this faint shadow is also a type of vitreous degeneration; it is larger than the dot-like floaters and is related to vitreous fibrosis.
Computer vision syndrome refers to the condition caused by prolonged computer use, leading to muscle strain and difficulty focusing, resulting in blurred vision, which is somewhat different from your experience.
However, it is essential to take breaks.
I recommend you have an eye examination to check for other abnormalities.

Today, I went for an eye examination, and they found a retinal tear, which was immediately treated with laser therapy on-site.
The doctor said there is no need to worry since it was detected early and is not serious.
I also asked the doctor about the issue I have when looking at bright backgrounds, and he said it is due to eye fatigue and irregular sleep patterns, which can cause difficulty focusing on bright backgrounds.
It could be glare or other issues, and he advised me to improve my sleep habits.

I am very worried that the diagnosis might be incorrect, and I fear I might have glaucoma or that other symptoms could worsen.
In my daily life, I have no problems seeing; my field of vision and color perception are normal.
Should I seek a second opinion at another hospital, or is it sufficient to follow this doctor's advice and just rest more? Thank you for your patience in reading this.

More Info

It sounds like you are experiencing a range of visual symptoms that are understandably causing you concern. Based on your description, it appears that you have been proactive in seeking medical advice and have undergone examinations that have ruled out some serious conditions. However, let’s break down your concerns and provide some clarity.

Firstly, the sensation of seeing a faint shadow or veil over your vision, especially against bright backgrounds, can be attributed to several factors. One possibility is that it could be related to the vitreous humor in your eye. As we age or due to certain visual stressors, the vitreous can undergo changes, leading to symptoms like the ones you described. This is often benign, but it’s essential to monitor any changes in your symptoms.

You mentioned that you have been using your computer and mobile devices extensively, which can lead to what is commonly referred to as Computer Vision Syndrome (CVS). Symptoms of CVS include eye strain, dryness, blurred vision, and discomfort, particularly after prolonged screen time. The fact that you are experiencing discomfort when viewing bright backgrounds may indeed be linked to visual fatigue from excessive screen use. It’s crucial to take regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps to alleviate strain on your eye muscles.

Regarding your concern about potential serious conditions like glaucoma, it’s important to note that your eye doctor has already performed necessary examinations, including checking for retinal issues. The fact that you had a retinal tear treated with laser therapy is a positive step, as early intervention can prevent further complications. Your doctor’s reassurance that there is no significant concern is a good sign. However, if you continue to experience discomfort or if your symptoms worsen, seeking a second opinion can provide additional peace of mind.

As for the advice to improve your sleep and reduce screen time, this is sound guidance. Poor sleep patterns and excessive screen exposure can exacerbate eye strain and fatigue. Ensuring you have a regular sleep schedule and taking breaks from screens can significantly improve your symptoms.

In summary, while your current symptoms may be uncomfortable, they are likely related to visual fatigue and possibly benign changes in your eye. Continue to follow your eye doctor's advice, prioritize rest, and consider reducing screen time. If your symptoms persist or worsen, don’t hesitate to seek further evaluation from another eye care professional for additional reassurance. Your vision is important, and being proactive about your eye health is the best approach.
