What is a significant change in eyeglass prescription?

A significant change in eyeglass prescription means that there has been a significant change in the correction needed to achieve clear vision. This change can result in a new prescription for glasses or contacts.

There are several reasons why a person's prescription might change significantly. One common reason is aging, as the eyes naturally undergo changes in their shape and function over time. Other factors that can contribute to changes in prescription include eye disease, injury, medication side effects, and changes in lifestyle or work habits (such as increased screen time).

It is important to regularly schedule eye exams to ensure that any changes in prescription are identified and addressed promptly. Failure to do so can result in eye strain, headaches, or other discomforts, and can also increase the risk of eye damage or vision loss.
