The quality and type of lens in dental loupes will determine its intensity as well as an enlarged and sharp image. When considering the type of lens used in his or her dental loupes, the dentist should remember a lot of things, including:
more comfortable Plastic lense
Plastic lenses are usually lighter
Larger lenses give brighter images
Depth of field (an ideal depth of field is 10 cm and can help reduce fatigue while working)
Field of view (a larger field of view is often recommended)
Weight of loupes
Availability of light
Ease of use
The dentist can use two types of dental loupes, including Flip-Up Loupes and Through-the-Lens (TTL) Loupes.
The Flip-up loupes can be attached to a movable arm or manually adjusted. They are usually much cheaper than other types of loupes. Flip-up loupes can be flipped when not in use, but are usually heavier than other loupes and provide a smaller field of view.
The through-the-Lens loupes are built into the eyeglasses and is designed for the dentist’s eyes. They are lighter than a reversing loupes and offer a wider field of view because the optical system is closer to the eye. TTL loupes cannot be moved out of position and are usually more expensive than flip-up loupes. Because the TTL loupes cannot be flipped, it may make it more difficult for the patient to communicate with the patient. TTL loupes also tend to have poor resale values because they are only suitable for the dentist they make.
The quality of lens determines the quality of the dental loupes, and the quality of the dental loupes determines the success of dental surgery. Therefore, the dentist should choose the most suitable dental binocular loupes to treat the dental patient.
