Magnification headlight buying guide
Modern dental loupes leave you wondering how dentists managed prior to lighted magnification. From diagnosing minute fractures to detecting tiny issues with a crown, magnification headlights provide a better visual and improve results.
But with so many options available on the market, how can you know which dental loupes are right for you?
How much magnification do you need?
Determining the ideal level of magnification is a balancing act that varies based on the type of work you use the loupes for. As magnification increases, field of view decreases, potentially to the point that you can only view one tooth at a time.
Typically, hygiene work is best done with 2x-3x magnification. This allows for several teeth to be seen in the field of view at one time. For a single crown or other single-tooth treatment, 4x-6x magnification will be more appropriate.
A narrower field of view also means less light will enter the lens. When shopping high magnification loupes, be sure they come fitted with high quality lighting.
Style and weight
Just like eyeglasses or sunglasses, magnification headlights come in an array of styles. As silly as it may sound, pick something that looks good on you. You’re more apt to use your dental loupes if you’re happy with the way they look.
Always try loupes on before you buy. You don’t want to invest in equipment that’s too heavy or uncomfortable.
Frames come in a wide range of materials like plastic, titanium or carbon fiber. Find the right balance between style and comfort. If you purchase your dental loupes online, be sure that the vendor has a generous return policy.
When reading individual product reviews, place heavy importance on the resolution and optical quality. Better optics provides better visual.
Invest in a high-quality lens for a more concise view with better contrast.
Flip-up versus through-the-lens
Some magnification headlights embed the loupe directly into the lens, whereas others provide a flip-up loupe in front of the lens. Both are great, but each type comes with its pros and cons.
- Through-the-lens (TTL) loupes are easy to use because the magnification is always in the right place – but when you want a normal field of vision you must remove the apparatus or look over the top of the lens.
- Flip-up loupes make it easy to switch back and forth between magnified and normal vision, but require more adjustments to get the loupe in its ideal position.
What is depth of field?
While field of view denotes how many teeth you can see at once through the magnifying lens, depth of field lets you know how many of those teeth will be in focus at one time. Dental loupes with a wide field of view but low depth of field will allow you to see multiple teeth at once, but only one tooth will be in clear focus at any given time.
The right focal distance
Focal distance is the distance from the end of the lens to the object you’d like to see in focus. Depending on how you sit when working, you may want to purchase a lens that has a longer or shorter than average focal distance to take advantage of the full ergonomic benefit.
Battery or corded lighting?
Some dental loupes include a battery-powered LED light built directly into the frame, while others run a wire down to a battery pack that clips onto your belt.
Battery-powered lights are great for the wireless convenience but also add weight. Again, try on both types of lighting to see which feels best.
As with any equipment investment for your dental practice, pay close attention to the manufacturer’s warranty and guarantee.
