The patient is waiting and attentively observing the visit, which emphasises the collaborative nature of the visit. This scene symbolises the important combination of high technology and medical knowledge that characterise the contemporary vision care. Every exact measure will help in building a vehement record of the health of the patient both in terms of sight and sight and this is what will guide correct diagnoses, prescriptions and the identification of future complications. It emphasises the fact that proper vision care has its foundation on the principles of scientific precision and precision in each process stage.
