Does eye exam have to include dilation?

Dilation is not always required during an eye exam but is often recommended for a comprehensive assessment of the retina and optic nerve. Dilation allows the eye doctor to get a better view of the back of the eye, helping to detect conditions such as glaucoma, diabetic retinopathy, and macular degeneration. However, some exams may be sufficient without dilation, especially if the patient has no significant risk factors or symptoms. Ultimately, the decision is made based on individual circumstances and the eye care provider's judgment.
