Why Has My Prescription Changed?If your vision hasn’t felt quite as sharp lately, you’re not alone. Many patients notice changes in their eyesight after summer — and it’s not always as simple as “needing stronger glasses.” In Queensland, prolonged UV exposure, dry air from constant air conditioning, and increased screen time can all affect how clearly and comfortably you see. Dry eye, in particular, can cause fluctuating vision that improves when you blink. That doesn’t necessarily mean your prescription has changed — but it does mean your eyes may need attention. Digital eye strain is another common culprit. Long hours on computers, tablets, and phones can lead to blurred vision, headaches, tired eyes, and difficulty focusing between distances. Sometimes patients assume their glasses are wrong, when in fact their visual system is simply fatigued. Seasonal allergies can also play a role. Itchy, irritated eyes may temporarily affect clarity and comfort, especially for contact lens wearers. Of course, genuine prescription changes do occur — and they can happen gradually. Even small shifts can impact night driving, reading clarity, or how comfortable you feel at work. If you’ve noticed headaches, squinting, blurred vision, or increased eye fatigue, it may be time for an eye examination. A comprehensive assessment can determine whether your prescription has changed, whether dry eye is contributing, or whether simple adjustments could improve your visual comfort. Clear, comfortable vision shouldn’t be something you “push through.” If things don’t feel right, book a check-up and make sure your eyes are working as well as they should.
