Do I Need to Change My Glasses After Increasing Contact Lens Prescription? - Ophthalmology

When it comes to the question of whether you need to change your glasses after an increase in your contact lens prescription, there are several factors to consider.
First and foremost, it’s important to understand that contact lenses and glasses correct vision in slightly different ways. Contact lenses sit directly on the eye, while glasses are positioned a distance away from the eyes. This means that the prescription for each can differ, and changes in one do not always necessitate a change in the other.
In your case, you mentioned that your contact lens prescription has increased by one degree, and you are experiencing some changes in your vision, such as the emergence of glare (which you referred to as "flash"). The recommendation from the optical shop to change your glasses is likely based on the fact that your vision correction needs have changed. If your glasses are still providing you with clear vision, particularly for activities you do regularly, such as reading or using a computer, you may not need to rush into changing them.
However, if your glasses are outdated and do not match your current prescription, wearing them could lead to visual discomfort, eye strain, or headaches, especially if you are using them for extended periods. Over time, not updating your glasses to match your current prescription could potentially lead to worsening vision or increased eye strain, as your eyes may be working harder to compensate for the incorrect prescription.

It’s also worth noting that if you are primarily wearing contact lenses during the day and only switching to glasses in the evening, the urgency to change your glasses may not be as high. However, if you find that your vision is becoming increasingly blurry or uncomfortable when wearing your glasses, it would be wise to consider an update.

In summary, while it may not be immediately necessary to change your glasses if you are still seeing well with them, it is important to have regular eye exams to monitor your vision and ensure that both your contact lenses and glasses prescriptions are up to date. If you experience any discomfort, persistent blurriness, or other visual disturbances, it would be prudent to consult with your eye care professional for a comprehensive evaluation. They can provide personalized advice based on your specific situation and visual needs.
In conclusion, while it may not be an urgent necessity to change your glasses right now, keeping your prescriptions updated is essential for maintaining optimal vision health. Regular check-ups with your eye care provider will help ensure that both your contact lenses and glasses are providing the best possible correction for your vision.
