Astigmatism: Can Eye Drops Change Your Prescription? - Ophthalmology

More Info

Astigmatism is a common refractive error that occurs when the cornea or lens of the eye is irregularly shaped, leading to blurred or distorted vision. It can be caused by a variety of factors, including genetics, eye injuries, or conditions such as keratoconus. When it comes to managing astigmatism, many patients often wonder if eye drops or medications can alter their prescription, particularly the astigmatism angle.

In your case, it seems that you have been experiencing some visual disturbances following a conjunctivitis episode. Your doctor has prescribed vitamin supplements and eye drops aimed at relieving eye fatigue, which is a common symptom associated with prolonged screen time or eye strain. However, it is important to clarify that while these eye drops may provide symptomatic relief, they do not have the capability to change the underlying refractive error, including the astigmatism angle.

The angle of astigmatism is determined by the shape of the cornea or lens, and it is a fixed characteristic unless altered by surgical intervention or significant changes in the eye's structure. Eye drops, particularly those designed for lubrication or fatigue relief, do not influence the physical shape of the cornea or lens, and therefore cannot adjust the astigmatism angle from 140 degrees to 180 degrees.

If your vision is clearer with a different astigmatism angle, it may indicate that your current glasses prescription is not optimal for your visual needs. In such cases, it is advisable to consider getting a new pair of glasses that accurately reflects your current refractive status. An updated prescription will ensure that you have the best possible vision correction, which is particularly important if you are experiencing discomfort or visual disturbances.

Moreover, it is worth noting that changes in vision can sometimes occur due to temporary factors such as inflammation or eye strain. After your conjunctivitis resolves, it is possible that your vision may stabilize, and a follow-up examination could provide further insights into your refractive status. If you continue to experience issues, it may be beneficial to consult with an optometrist or ophthalmologist who can perform a comprehensive eye exam and determine the best course of action.

In summary, while eye drops can help alleviate symptoms related to eye fatigue and dryness, they will not change the prescription for astigmatism. If you find that your vision is clearer with a different astigmatism angle, it is advisable to get a new pair of glasses that accurately reflects your current needs. Regular eye exams are essential for monitoring changes in vision and ensuring that you have the appropriate corrective lenses.
