Atropine Eye Drops: Effects on Near and Distant Vision - Ophthalmology

Share to:

After using a dilating eye drop, both distant and near vision become blurry?


Hello Doctor, I am currently a senior in high school, and after starting my senior year, I feel that I have developed myopia.
Yesterday, I went to see a doctor, and my right eye measured -1.50 diopters and my left eye -1.00 diopter.
The doctor prescribed me atropine and told me that since my myopia is not severe, I could apply it to my left eye one day and my right eye the next day, or alternate every two days.
However, when I picked up the medication from the pharmacist, they advised me to apply it to both eyes every day.

Question 1: Should I follow the doctor's instructions or the pharmacist's? After applying the drops to both eyes that night, I did experience photophobia and difficulty seeing near objects as side effects.
However, what puzzles me is that my distance vision is also blurry, and it seems worse than when I hadn't used the dilating drops.

Question 2: Is this a normal phenomenon? Thank you for helping me clarify these concerns!

More Info


Atropine eye drops are commonly used in the management of myopia (nearsightedness) and have been shown to be effective in slowing its progression. However, like any medication, they come with potential side effects and considerations that need to be understood, especially for young patients like yourself.


Question 1: Should I follow the doctor's or the pharmacist's instructions?
In general, it is best to follow the instructions given by the prescribing physician, as they are familiar with your specific case and have the most comprehensive understanding of your eye health. The doctor likely prescribed atropine with a specific regimen in mind, considering your current level of myopia and overall eye condition. If the doctor advised you to alternate drops between your eyes, it may be to minimize side effects while still providing therapeutic benefits.

On the other hand, pharmacists provide valuable information on medication usage and can clarify how to take the medication safely. If there is a discrepancy between what your doctor and pharmacist said, it is advisable to return to your doctor for clarification. Communication is key in healthcare, and ensuring that you understand your treatment plan is essential.


Question 2: Is it normal to experience increased blurriness in both near and far vision after using atropine?
Yes, experiencing blurred vision, especially for near objects, is a common side effect of atropine eye drops. Atropine works by paralyzing the ciliary muscle, which is responsible for adjusting the lens of the eye for focusing. This leads to difficulty in seeing close objects, a condition known as "cycloplegia." Additionally, atropine causes pupil dilation (mydriasis), which can lead to increased sensitivity to light (photophobia) and may also affect your ability to focus on distant objects temporarily.

The blurriness you are experiencing, particularly for distant vision, could be due to the effects of the medication. While atropine is primarily used to manage myopia, its side effects can sometimes lead to temporary visual disturbances. This is particularly true if the dosage is higher than what your eyes are accustomed to or if you are sensitive to the medication.


Additional Considerations
1. Duration of Effects: The effects of atropine can last for several hours, and it may take some time for your vision to stabilize after using the drops. If you find that your vision remains blurry for an extended period, or if you experience significant discomfort, it is important to consult your eye care provider.

2. Long-Term Use: Atropine is generally safe for long-term use in children and adolescents when monitored by an eye care professional. Studies suggest that lower concentrations (like 0.01% or 0.025%) can be effective in controlling myopia with fewer side effects compared to higher concentrations (like 0.1% or 0.5%).

3. Monitoring: Regular follow-up appointments with your eye doctor are crucial. They will monitor your vision and the effectiveness of the treatment, adjusting the dosage or frequency as necessary.

4. Lifestyle Adjustments: While using atropine, it may be beneficial to limit activities that require intense near vision, such as reading or using digital devices, especially in bright light conditions. Wearing sunglasses outdoors can help mitigate photophobia.

In summary, while it is normal to experience some blurriness and sensitivity after using atropine, it is essential to communicate with your healthcare providers about any concerns you have. Following the doctor's instructions is generally the best course of action, and regular monitoring will help ensure that your treatment is both effective and safe.
