Having established the main reason for the visit, the Columbus optometrist reviews the current vision correc¬tion from the focimeter result. The prescription identifies the patient as myopic or hyperopic, whether the patient has astigmatism, and also whether or not the patient has presbyopia (with a reading add - in the form of varifocals, bifocals or a separate pair of spectacles specifically for near work or 'reading glasses'). The optometrist records the vision of the patient without any correction, which indicates the necessity of vision correction (e.g. for driving). This is referred to as the 'unaided vision" or unaided visual acuity (VA). The optom¬etrist measures the standard of vision with the current correction in order to establish how well the current spectacles are performing and if there is room for improvement. Some patients are aware that their vision has deteriorated, and therefore expect to have a change in prescription to make their vision improve, whereas others attend for reasons of habit and arc surprised to learn that a new prescription will be a significant improvement. This 'before' and 'after' information is helpful when advising the patient, and it is also very useful for the dispensing optician when the patient is deciding on new spectacles and also when the patient collects their new spectacles - the records reflect what improvements the patient should expect. Many patients are concerned about whether or not they have given the 'right answer' during the course of the eye examination when their prescription is being evaluated. Few patients are aware that the Columbus Optometrist is able to make an accurate measurement of the prescription of each eye using an optical instrument such as retinoscope. The optom¬etrist looks through the eyepiece of the retinoscope in the darkened consulting room. A streak or spot of light from the retinoscope is moved across the patient's pupil, which glows red when viewed through the retinoscope just like in a flash photograph. The way the light moves across the pupil is affected by the prescription of the eye, and the optometrist is highly skilled in interpreting this. Prescription lenses are placed into the trial frame or phoropter head, until the correct prescription is reached - this is often termed the 'neutralization point' and the optometrist is then fully aware of the extent of the prescription in each eye. This is the very reason why patients should not fear giving the 'right' or 'wrong answer - the optometrist already knows the prescription measurement. It is important to consul an optometrist in order to correct ones vision problems and eye related problems. Make sure to select the best and qualified optometrist.
