Optometry and Dry Eye Issues

Hello, Doctor.
Over a year ago, I got my glasses at a quick optical shop.
At that time, I was quite fatigued after work during the eye exam, and the prescription was R 375 and L 400.
I did not return for any adjustments afterward.
Recently, I evaluated the possibility of laser vision correction and went to a clinic for an eye exam first thing in the morning.
Using a machine designed for viewing hot air balloons, my vision was measured at R 300 and L 350.
Subsequently, an optometrist performed a refraction and confirmed that with R 300 and L 350, I could see clearly.
However, during the test with the single-eye vision chart, when I reached the 1.2 line with five symbols, only 1 to 2 symbols were somewhat blurry, making it difficult to judge.
The optometrist advised me to take my time.
I indicated the possible direction of the symbols, and it turned out to be correct.
The optometrist informed me that typically, a prescription of 1.0 is sufficient for glasses.
My current prescription is significantly higher than the recent measurements, which is only to make things appear brighter, not necessarily clearer.
They also suggested that if I do not plan to undergo laser treatment soon, I should change my prescription to avoid eye strain.

I would like to ask:
1.
What could be the reason for the difference in prescription between the two eye exams?
2.
With a difference of 50 to 75 degrees between the optical shop and the clinic, and having used the higher prescription glasses for over a year, could this cause any issues for my eyes?
3.
Would you recommend lowering the lens prescription to R 300 and L 375 as measured at the clinic?
4.
During the clinic's test, my tear production was only 5mm in both eyes, and the consultant mentioned that this indicates a more severe dry eye issue.
Could this problem be related to using a higher lens prescription?
5.
Can dry eye issues be improved by supplementing with lutein, fish oil, and applying warm compresses to the eyes?
Thank you for your assistance, Doctor.

Hello! Thank you for your detailed questions regarding your vision tests and dry eye issues. It’s important to address these concerns as they can significantly impact your quality of life. Let’s break down your questions one by one.

1. Differences in Vision Test Results: The variation in your prescription between the two vision tests could be attributed to several factors. First, the testing conditions can greatly affect the results. If you were fatigued during the first test, your eyes may not have performed optimally, leading to a higher prescription. Additionally, the equipment used and the expertise of the technician can also influence the results. Different machines may have varying calibration, and the subjective nature of vision testing means that slight differences in how you perceive clarity can lead to different outcomes.

2. Impact of Using a Higher Prescription: Wearing glasses with a significantly higher prescription than necessary can lead to discomfort and visual fatigue. Over time, this may cause symptoms such as headaches, eye strain, and even exacerbate dry eye symptoms. However, if you are able to see clearly with your current prescription, the immediate impact may be minimal. It’s essential to monitor how your eyes feel and consult with an eye care professional if you experience discomfort.

3. Adjusting Your Prescription: It is advisable to consider adjusting your prescription to align more closely with the recent test results (R 300, L 350). This adjustment can help reduce eye strain and improve your overall visual comfort, especially if you spend long hours in front of screens. However, any changes should be made in consultation with your eye care provider, who can assess your specific needs and the potential benefits of the adjustment.

4. Dry Eye and Prescription Strength: Your reported tear production of only 5mm indicates a significant dry eye condition. While higher prescription lenses themselves do not directly cause dry eyes, the discomfort from wearing glasses that do not match your optimal prescription can lead to increased eye strain, which may exacerbate dry eye symptoms. It’s crucial to address the dry eye issue separately, as it can affect your overall visual comfort and quality of life.

5. Improving Dry Eye Symptoms: Dry eye can often be managed through various methods. Supplementing with omega-3 fatty acids (found in fish oil) and lutein may help improve eye health, but they are not a cure-all. Regular warm compresses can also provide relief by helping to unclog blocked glands in the eyelids. Additionally, using artificial tears or lubricating eye drops can help alleviate dryness. It’s essential to consult with your eye care professional about the best treatment plan tailored to your specific condition.

In summary, it’s crucial to have regular eye exams and communicate any changes in your vision or discomfort to your eye care provider. They can help you navigate the complexities of your vision needs and dry eye management. Remember, your eye health is paramount, and addressing these issues proactively can lead to better outcomes. If you have further questions or concerns, don’t hesitate to reach out to your eye care professional for personalized advice.
