Frequently Asked Questions

  • What makes the Kepler Kompakt more expensive than the HD?
    The Kepler is a much more complex lens system than the Galilean HD. The Kepler Kompakt has prisms inside the ocular, so is much more difficult to construct. Plus ExamVision makes it very short and light! That is why it is more expensive. The construction also makes the Kepler a little heavier (approx 25g), but is still well balanced and lightweight compared to other prismatic loupes.
  • Will I see a difference between the image of a Kepler Kompakt and an HD loupe?
    When you compare the image between the two systems, you will notice an edge to edge sharpness in a Kepler system, which cannot quite be achieved in Galilean. This sharpness comes at the price of flexibility - the Kepler needs to be adjusted very precisely to give this sharpness, and you won't get the same freedom of movement as with a Galilean HD. We advise you to try both and see which you prefer for the work you do!
  • I have a working distance of 55cms – does this influence my loupe choice?
    No it doesn’t influence on your magnification. But it is important to note that it is only possible to achieve a really long working distance (over 62cms) with a Kepler system in the higher magnifications (3.5+) - in a Galilean system it is physically impossible to make the working distance this long without losing a little magnification.
  • What does fine-focus mean?
    The Kepler Kompakt has a fine-focus feature, which means that you can manually adjust each ocular just a little if necessary to perfect the focus, then lock it in place. ExamVision will have already set your working distance to your specifications, but the fine-focus means that you can achieve a perfect image.
  • Which magnification is right for me?
    You will have to try various degrees of magnification to find out which is best suited to you, your sight and the work you do.

    If you are using magnification all day long, we recommend 2 to 3 times magnification, as these levels of magnification give you an optimal depth of field (i.e. freedom to move back and forth with your subject in focus). This helps you to maintain a relaxed posture through the day. Field of view is also widest at these magnifications.

    Higher magnifications are best suited to specialist work, usually for a few hours at a time. Many of our customers have a 2.3 loupe for general work, and use them in combination with a 3.3, 3.8, 3.5, 4.6 or 5.7 for intricate procedures.

  • I can see perfectly well. Why do I need loupes?
    If you can't see it, you can't treat it! Magnification allows you to see the small details better. You will be able to work with a greater degree of precision, making diagnosis and treatment safer, more reliable and faster. Your ergonomic position is also improved when you use magnification – you don’t have to lean in close, bending your back and neck to see the details.
  • Will my eyesight be weakened by using magnification at work?
    No. Your eyes will still get plenty of healthy exercise, but they won't be strained.
  • I am really short-sighted. Which loupes should I buy?
    Whichever style of ExamVision loupe you choose, we can fit your prescription into the loupe and into the outer lenses, so you can see both your work area and for example your computer screen in perfect focus. Your loupes will be custom made – they will be perfect for you.
  • Which is better, flip-up or TTL?

    This is a question of personal preference. ExamVision believes that the best possible optical performance is achieved by bringing the loupe as close as possible to the eye, which means we would always recommend a TTL (through-the-lens) solution.

    We no longer make a flip-up model – instead we concentrate on making individually customized TTL loupes.

    Perhaps you are considering upgrading from your existing flip-up to a TTL? Ask yourself how often you actually flip the loupe out of the way during a day's work. If you don't currently use your flip-up function, then we would recommend the ExamVision HD TTL as your perfect upgrade.

  • Do all loupes use the same standard for measuring degree of magnification?
    No. It depends on the manufacturer and the loupe system. Unfortunately there is no generally accepted standard, so a 2.3 magnification in one brand may feel the same as a 2.5x magnification in another brand. ExamVision always measure the ‘angular magnification’ at a working distance of 40cm. Magnification is a good starting point, but you need to test a pair of loupes and consider the whole package before you make your purchase: clarity, comfort, width and depth of field.
  • Why are your loupes so expensive?
    ExamVision loupes and lights are designed and produced without compromise in Denmark. Each pair is custom-made to suit the customer's eyesight and working practices. We use only the highest quality materials, and features like Hi-Index glass come as standard. Our dealers in different countries are all individually trained in fitting ExamVision loupes, and many have opticians on the team to ensure a perfect service. This is why our loupes may cost a little more than the competition – but when you first try ExamVision you will see clearly that they are the best!
  • If my eyesight changes, how do I change my loupes?
    We offer to correct your loupes – both telescopes and prescription lenses – to suit your new prescription. If we order the new prescription lenses for you in advance, then you send in the loupes, we will make the correction in less than a working week before it is sent back via your local dealer. Your loupes will get a service at the same time!
  • I live in an area not covered by your distributors. Can I still buy your loupes?
    Drop us a line at office@exam-vision.com, and we should be able to help.
  • I have been told I need to sit up straighter to avoid neck and back strain. How do loupes help me do that?
    Because you see a magnified image, you don't need to lean into your subject (your patient for example). This allows you to sit up straighter for long periods at work, relieving strain on the muscles in your back and neck. ExamVision loupes also have an excellent depth of field (circa 20cm), so you can move back and forth while keeping your subject in focus, which also helps to avoid stiffness.

    If you experience back and/or neck stiffness or pain at work, then it may be advisable for you to use our Prisma Lens System TM built into your loupes. The prism refracts the image, so you can sit up even straighter. Please discuss this in more detail with your local ExamVision dealer.

  • I own a product that I dont see on the website. Is it discontinued?
    ExamVision is constantly improving its range of products to take advantage of improvements in materials and design.

    Therefore, a number of products have been discontinued, but ExamVision will of course continue to service and maintain these products for as long as possible.

    Discontinued products:

    Lite loupes: try the Essential instead

    HD 4.2 loupe: you could consider a HD 3.8 or a Kepler Kompakt 3.5 or 4.6

    HD 5.0 loupe: try the Kepler Kompakt range – up to 5.7 times magnification!

    Basic LED, Essential or Essential Upgrade LED: The Nano Essential LED might suit you

    Focus™ XP: Try the Focus™ Bright with the Xtend control unit. You should find it gives a much more even light spot.

    Fibre Optic Focus lights: These are excellent lights, and we will continue to service them. But if you are looking for a new light, consider one from the portable Focus LED range.
