If you're ready to purchase a pair of loupes, a guide to the types available and important specifications can help you choose the best pair for your work.
I have worn loupes since I was a dental hygiene student, and buying a pair was one of the best decisions I've ever made. Loupes have given me the ability to see better and have protected my body from poor posture. If you're ready to purchase a pair of loupes, a guide to the types available and important specifications can help you choose the best pair for your work.
Once you've determined which kind of loupes is best suited to your vision and working habits, you should familiarize yourself with a few key specifications: working distance, depth of field, field of view, magnification and declination angle.
If you decide on TTL loupes, you will also need to have your pupillary distance measured. This is the distance between the center of your pupils.
Is a headlight attached to your loupes worth it? Yes! Using a headlight allows for intense focal illumination and eliminates shadowing. It also indirectly reduces shoulder fatigue by eliminating the need to reach up and adjust an overhead lamp. Most companies offer discounts if a light is purchased with loupes, but make sure to ask about the warranty period on all components.
Light intensity can differ between products, so be sure to do your homework in choosing what is right for you. Headlights can be corded or cordless. Corded models tether a clinician to a battery pack but offer more light adjustment. Cordless models tradionally store batteries attached to the arm of the frame adjacent to the ear. Models are now also available with the battery housed within the arm of the frame, as well as threaded in to the headlight itself. When considering loupes, check on the length of time for the battery life before it needs to be recharged. Battery replacement can be expensive, so it is important to ask questions about the batteries prior to purchase.
Dental conventions are a good way to investigate different options for dental hygiene loupes. Company representatives and booths are also a great resource for questions about warranties, payment plans, discounts and customization.
Once you have seen and touched the loupes you're most interested in, ask a sales representative at the convention to set up a time to come to measure you at work. The most accurate loupes measurements are taken at your operatory. If you are measured at a dental convention, the loupes may need to be sent back to the company for adjustments.
Understanding the types of loupes and the terminology before you start shopping for loupes can help you focus on what you're looking for. It is never too early or late in your career to invest in a quality pair of loupes.
