Can Atropine Sulfate Reduce My Eye Prescription Before a Vision Test? - Ophthalmology

Atropine sulfate is a medication commonly used in ophthalmology, primarily for its ability to dilate the pupils and relax the ciliary muscle of the eye. This action can temporarily affect the way the eye focuses, which is particularly useful during eye examinations. However, the question of whether atropine can reduce your eye prescription before a vision test is more complex.

Firstly, it is important to understand that atropine is not designed to permanently reduce myopia (nearsightedness) or astigmatism. Its primary use in the context of myopia management is to slow the progression of the condition, particularly in children and adolescents. Studies have shown that low-dose atropine can help in controlling the progression of myopia, but it does not reverse existing refractive errors or significantly alter the degree of myopia in adults.

In your case, you mentioned that your current prescription is quite high, with left eye at -625 degrees and right eye at -525 degrees. The use of atropine may temporarily affect your ability to focus, which could lead to a different measurement during a vision test. However, this does not mean that your actual refractive error has changed. The temporary effects of atropine can lead to a situation where your vision appears better than it actually is, especially if the test is conducted shortly after administration of the drops. This could potentially result in a lower prescription being recorded, but it would not reflect a true improvement in your eyesight.

Moreover, the effects of atropine can vary from person to person. Some individuals may experience significant difficulty focusing on near objects, while others may not notice much difference. This variability can complicate the interpretation of vision test results following atropine use.

Regarding your upcoming vision test for the 中正預校 (National Chung Cheng University), it is crucial to communicate with your eye care provider about your concerns. They can provide guidance on the timing of the atropine administration relative to your vision test. Ideally, you would want to have the test conducted when the effects of the atropine have worn off to ensure that the results accurately reflect your true refractive error.

In addition, it is worth noting that atropine can have side effects, such as light sensitivity due to pupil dilation and difficulty focusing on near objects. These effects can be uncomfortable and may impact your daily activities, especially if you rely on your near vision for tasks like reading or using a computer.

In summary, while atropine sulfate can temporarily alter your ability to focus and may affect the results of a vision test, it is not a method for reducing your eye prescription in a meaningful or permanent way. If your goal is to achieve a specific standard for your vision test, it is best to discuss this with your eye care professional, who can help you navigate your options and ensure that your vision is assessed accurately.
