Eye exam consisted of four parts. First was peripheral. You stick your head in this half sphere. You look straight ahead and click a button every time you see a light in your periph. Then you do far and near sight test and color test like in the states. Then your binocular vision is tested. Hard to explain. Try looking it up. It has to do with one eye being manipulated by a prism and causing a picture to double. Then you must refocus to make it one. Periph is checked again with that doc. Then eyes get dialated and your check for pressure and glaucoma.
