Eye fatigue and floaters?


Hello Doctor, recently I've been staying up late and using electronic devices a lot, which has made my eyes very tired.
This week, when I woke up in the morning, I noticed a spot in my left eye that moves with my line of sight.
The color is somewhat transparent, and besides the spot, there is also a transparent line.
I have astigmatism with -3.50 in my left eye and -2.50 in my right eye, and my myopia is less than -2.00 in both eyes.
Currently, it doesn't significantly affect my daily life, but I can see it from certain angles when I focus on it.
There was a time before when I experienced something similar due to eye fatigue and late nights, but it disappeared after I normalized my sleep schedule.
I'm wondering if this time it will go away on its own if I avoid eye strain, or if it might have been there all along.
Should I get it checked out? Thank you.

The symptoms you described are more akin to floaters.
It is advisable to undergo a thorough dilated fundus examination.

More Info


Understanding eye floaters can be quite concerning, especially when they appear suddenly or change in nature. Eye floaters are small spots, lines, or cobweb-like shapes that drift through your field of vision. They are usually harmless and are caused by tiny pieces of gel or cells inside the vitreous, the clear gel-like substance that fills the eye. As we age, the vitreous can shrink and become more liquid, leading to the formation of these floaters.

In your case, you mentioned that you have been experiencing fatigue from late nights and excessive screen time, which can indeed contribute to eye strain. The appearance of floaters, particularly after periods of eye fatigue, is not uncommon. It is possible that the floaters you are seeing are a result of your recent lifestyle changes, and they may disappear as your eyes recover from fatigue and you return to a more regular sleep schedule.

However, it is essential to monitor the situation closely. While most floaters are benign, there are certain symptoms that warrant immediate medical attention. If you experience a sudden increase in the number of floaters, flashes of light, or a shadow or curtain effect in your peripheral vision, you should seek help from an eye care professional as these could be signs of a more serious condition, such as a retinal tear or detachment.

Given your current situation, where you have noticed new floaters in your left eye that move with your gaze and are somewhat transparent, it would be prudent to schedule an eye examination. An eye care professional can perform a thorough examination to rule out any underlying issues and provide you with peace of mind. They can also assess the health of your retina and vitreous, ensuring that there are no complications that need to be addressed.

In terms of management, reducing eye strain is crucial. Here are some tips that may help alleviate your symptoms and prevent further eye fatigue:
1. Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break to look at something 20 feet away. This helps reduce eye strain from screens.

2. Ensure Proper Lighting: Make sure your workspace is well-lit to avoid straining your eyes while reading or working on screens.

3. Stay Hydrated: Dehydration can contribute to eye fatigue, so make sure you drink enough water throughout the day.

4. Limit Screen Time: Try to reduce the amount of time spent on screens, especially before bedtime, to improve your sleep quality and overall eye health.

5. Regular Eye Exams: Keep up with regular eye check-ups to monitor your eye health, especially since you have a history of astigmatism and myopia.

6. Consider Blue Light Glasses: If you spend a lot of time on digital devices, blue light blocking glasses may help reduce eye strain.

In conclusion, while your floaters may be a temporary issue related to eye fatigue, it is always best to err on the side of caution and consult with an eye care professional. They can provide personalized advice and treatment options based on your specific situation. Taking proactive steps to care for your eyes will help ensure your vision remains clear and healthy.
