Squinting at distance, removing your glasses to read, more frequent headaches, or tired eyes after screen work can all suggest your prescription needs a review. Night driving that feels harder than it used to is also worth mentioning. For many drivers heading home along Highway 404 or Bayview Avenue after dark, that change is often the first thing they notice.
Not every change is about the prescription. Lens design, frame fit, dry eye, or an eye health concern can also play a part. A full assessment helps your optometrist sort through the possibilities and recommend what will actually help.
