A noticeable change in glasses power can happen for several reasons. It may be related to:
•Changes in the shape of the eye or focusing system
•Age-related changes in near vision
•Uncontrolled diabetes, which can temporarily affect vision
•Dry eyes, which can cause fluctuating or blurred vision
•Changes in the cornea, such as keratoconus
•Certain eye conditions or medications
⚠️ *Important* : If your glasses power changes quickly, especially if the change is accompanied by sudden blurred vision, eye pain, flashes, or many new floaters, an eye examination is recommended rather than simply changing your glasses.
