There aremany on OptiBoard who believe that they can become competent Opticians and Contact Lens Fittersby studying only from a textbook.
Now there personswho can read ‘Systems for Ophthalmic Dispensing’ and Ellen Stoner’s ‘OpticalFormulas’ and then understand and retain enough to pass the basic ABO or NCLE.After all, there is no hands-on ‘practical’ testing done on these basic exams,and any optical formula questions on these tests are of the most rudimentarykind.
But thebasic ABO is entry-level optical knowledge and certainly doesn’t train or test someonein troubleshooting an eyewearer’s optical problem. Only a formal opticianrycourse with qualified instructor can provide the student with instant answersthey or another student might pose in a difficult area of opticianry formulas.Formulas are first explained on the whiteboard and then homework is assigned toensure a fine grasp of the theory. Once so learned, the practical implicationsof the formula are explained so that the student eventually develops an understandingof the whole of opticianry from the various optical formula parts.
Formal opticianryis taught in layered portions, the student needing an understanding of the mostbasics before advancing to the next upper level of optical knowledge. In thisway the student eventually realizes how optical theory meshes with practical hands-ontechniques to produce an optician that is competent and confident to deal withanything that may occur in the field.
Doctorsshare some of the blame as do some US State regulators. Nearly all regulators requireonly basic ABO as part of their registration process. This meaningless ABO requirementfrom formally trained opticians is ludicrous, but it maintain a higher ABO Basicpass rate than if these opticianry graduates were required to pass the morerigorous ABO Advanced.
The phrase ‘Theydo not know what they do not know’ continues to ring true today.
