Details: This poster is of a vintage ad. It shows a boy reading a book at his desk. Standing over him is a teacher holding a piece of paper. At the top it says John is not really dull. He may only need his eyes examined. The text size gets smaller and smaller, similar to an eye test.
An eye examination is a battery of tests performed by an ophthalmologist, optometrist, or orthoptist assessing vision and ability to focus on and discern objects, as well as other tests and examinations pertaining to the eyes. Eye examinations may detect potentially treatable blinding eye diseases, ocular manifestations of systemic disease, or signs of tumours or other anomalies of the brain. Ideally, the eye examination consists of an external examination, followed by specific tests for visual acuity, pupil function, extraocular muscle motility, visual fields, intraocular pressure and ophthalmoscopy through a dilated pupil.
This poster is usually printed with a thin white edge border.
