Astigmatism: New Glasses and Vision Clarity Issues - Ophthalmology

Hello! Thank you for your question regarding astigmatism and the challenges you are facing with your new glasses. It’s understandable to feel concerned about your vision, especially when preparing for exams and spending long hours reading. Let’s break down your situation and address your concerns.

Firstly, astigmatism is a common refractive error caused by an irregular shape of the cornea or lens, leading to blurred or distorted vision. When you received your new glasses, it’s not uncommon to experience some initial discomfort or blurriness, especially if the prescription has changed significantly. The fact that you felt clearer vision initially suggests that the new lenses were indeed an improvement at that time. However, the subsequent increase in astigmatism by 50 degrees could indicate a few possibilities.

1. Adjustment Period: It’s possible that your eyes are still adjusting to the new prescription. This adjustment period can vary from person to person, and during this time, you might experience fluctuations in clarity. If the blurriness persists beyond a few weeks, it would be wise to revisit your optometrist for a follow-up examination.

2. Prescription Accuracy: The increase in astigmatism could also be due to an error in the lens prescription or fitting. If the lenses are not aligned correctly with your eyes, it can lead to visual distortions. It’s essential to ensure that the new glasses are made accurately according to your latest prescription.

3. Eye Strain: Given that you are studying for exams and spending extended periods reading, eye strain could be contributing to your visual discomfort. Prolonged near work can lead to symptoms such as headaches, blurred vision, and fatigue. It’s crucial to take regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.

Regarding your question about wearing a second pair of glasses with a lower prescription, this can be a double-edged sword. On one hand, using glasses with a lower prescription for reading may provide temporary relief and reduce eye strain. However, if the prescription is too weak, it could lead to further visual discomfort or strain, especially if you are trying to see clearly at a distance. It’s essential to consult with your optometrist about the best approach to manage your vision needs during this study period.

In terms of long-term effects, wearing glasses with an incorrect prescription can lead to visual discomfort, but it typically does not cause permanent damage to your eyesight. However, it’s crucial to monitor your symptoms and seek professional advice if you notice significant changes in your vision.

Lastly, maintaining good eye health is vital, especially with your increased study load. Ensure you are practicing good habits, such as proper lighting while reading, maintaining a comfortable distance from your books, and staying hydrated. If you continue to experience issues, consider scheduling an appointment with your eye care professional to reassess your prescription and discuss your symptoms in detail.

In summary, your experience with new glasses and astigmatism is not uncommon, and there are several factors at play. Regular follow-ups with your optometrist, practicing good eye care habits, and being mindful of your visual comfort during study sessions will help you navigate this situation effectively. Best of luck with your exams, and take care of your eyes!
