Raise your hand if you remember needing a pattern to edge lenses. How about heat-treating glass lenses? If you didn’t raise your hand, no worries: we have come a long way these last twenty years. As with any industry, change is inevitable and necessary; the optical industry is no different. In order to keep up, however, the classroom must also change to meet the industry standards.
Goodwin College’s Vision Care Technology program had their annual Paint Night fundraiser in November. These fundraisers provide the means to send students to optical conferences around the nation. This year our administrative assistant, Sara, chose a lighthouse as the subject. Little did she know the connection that lighthouses have with opticians.
Parts 1 through 4 of this series described the importance of determining the visual axis measurement to maximize patient visual comfort and satisfaction with PALs. This final installment introduces methods and devices to obtain that measurement.
Ever heard this? “Seems like I need to rotate my head to read clearly through one of my lenses.” I’ve been annoyed and frustrated when I thought that the lenses I dispensed were measured and fit correctly and yet the patient, the real expert, says, they aren’t. If these lenses were correctly placed, patients would have good binocularity and comfort at near, not the stereoscopic disruption and discomfort that they are experiencing.
In Part 1, we discussed Position of Wear measurements and how they affect compensated power. Now you’ll see why. Are all these measurements necessary? The answer is yes and no. To create compensated lenses, we must use values for one or more of the key POWs.
