It’s important to remember that 20/20 vision doesn’t necessarily mean that your eyes are healthy. In fact, as many as one in six people with potentially serious eye disease still have ‘normal’ visual acuity.
Many serious conditions have no symptoms at all: no blur, no redness, no headache, no pain, no tearing … nothing. Glaucoma, age-related macular degeneration, and diabetic retinopathy are examples of conditions that are usually discovered through regular comprehensive examinations. A significant amount of damage can occurs before symptoms become evident: damage that is often preventable with early diagnosis and treatment.
For this reason, we recommend comprehensive examinations at regular intervals for patients of all ages. As a rule, children and seniors should be seen annually (and are insured by OHIP at this schedule), and adults at least every two years or as recommended by the optometrist.
Your mother was right, yet again: an ounce of prevention is worth a pound of cure.
