Pre-testing equipment includes Digital Fundus Retinal Photography, at NO extra charge.
This allows the optician to explain what the back of your eyes are telling him about your eye health, and your general health to a certain degree with things such as blood pressure control, cholesterol levels, macular health etc.
The testing equipment is all state of the art computerised machinery. No more looking at a box on the wall whilst wearing frames into which lenses are put in and removed. You simply look through what is called a Phoropter Head, directly at a screen with a chart on it. It is a bit like looking through a pair of binoculars, as simple as that.
