SheerVision Signature Flip-Up Loupes

Care and Use Instructions

Revised 03-13-2007B

The purpose of this information is to enable SheerVision distributors to provide new loupe users with specific instructions to greatly increase customer satisfaction with their loupe purchases, and significantly reduce the return of loupes.

For additional information on the factor inspection testing of Flip-Up Loupes please refer to: SheerVision Signature Flip-Up Loupes Testing Information & Documentation, Revised 01-17-2007D

SheerVision wants everyone in the medical and dental professions to benefit from using loupes to improve the quality of patient care as well enhance the career spans of loupe users.
With each loupe shipment to a customer we include a sheet and affix a sticker to the product. Both communicate to contact SheerVision by telephone for “Focusing Instructions”.
The majority of customers do call in for these instructions. The goal of providing these instructions is:

  1. To increase customer satisfaction with their loupe purchases, and significantly reduce the return of loupes.

  2. To log in the purchase date of the loupes for use in warranty date tracking.

  3. To assist the customer to insure that the loupes are used in a method that reduces the chance of a customer caused defect.

The following informational topics are reviewed with the customer during the “focusing instructions”:

  1. Focusing the loupes

    1. How to set the correct Pupillary distance

    2. Using the safety strap

    3. Loupe “break in” period – initial usage guidelines

  2. Using the lens cap covers

  3. Using the flip paddle to prevent contamination

  4. Using the side shields (titanium framed loupes only)

  5. Proper loupe cleaning methods

SheerVision recommends that all of our distribution partners also impart this information to their customers.

A. Focusing Instructions:

  1. Put the loupes on and flip the barrels all the way down toward your viewing target. You should be approximately 16 inches/400 mm* away.

  2. Tighten the safety strap so that the loupes remain in a comfortable position.

  3. Use your finger or dental model as a viewing target.

  4. Adjust the interpupillary knob so that the barrels are as far apart as possible.

You should now see two images of your finger or dental model.

  1. Slowly turn the interpupillary knob again until you see a single focused image. Your viewing target should appear in either a circle or an oval.

*Working Distance Designation Focus At:

Short 11 Inches / 280 mm

Medium 15 Inches / 380 mm

Long 17 Inches / 430 mm

Extra-Long 19 Inches / 480 mm
This distance will vary depending on the working distance the customer selected at the time of purchase. If this distance does not match the method the customer uses perform their procedures (i.e. you find that they are leaning in or leaning back) please contact the customer service department during the initial trial period to arrange for a working distance exchange.
Additional Focusing Notes

Be careful that the user does not over-adjust their loupes. Bringing the optical barrels too close together can result in eye strain, causing eyes to become fatigued. If you see two circles, two images in a single circle, or an uneven edge around the target, repeat steps 4 and 5 above until the target becomes a single, focused image.

Using SheerVision Loupes

Most new users of magnification devices experience some initial feelings of awkwardness and disorientation in the first few weeks of use. These feelings are similar to the times you had your first pair of glasses or had your prescription changed.

If the customer experiences these feelings, spend only 30-60 minutes at a time performing simple procedures, and then let your eyes rest. As their eyes accustom themselves to the increased magnification, and your hand-eye coordination develops, you can extend the time you use your loupes. The stronger the level of magnification of your loupes, generally the longer the adjustment period will be.
B. Use of the Lens Cap Covers:
We provide lens cap covers for all of its loupes. These covers are designed to project the lens from scratches or damage, which can be caused by flying debris. We recommend that they be used at all times. To install the covers just slide them over each optical barrel.

C. Use of the Flip Paddle:
The Flip Paddle included with your device allows you to lift the loupes from your field of vision with a sterilizable tool without contaminating your sterile gloves or instruments.
You can cold-sterilize the Flip Paddle before a procedure and snap the instrument into your loupes without touching the loupes.
Please note that the Flip Paddle has a top and a bottom side.
To attach your Flip Paddle:

  1. Identify the top and bottom of the paddle. Please note that the bottom clasp is wider than the top clasp.

  2. Slide the bottom clasp of the paddle beneath the interpupillary knob. The top clasp should slide over the top of the knob at the same time.

  3. When the clasps snap around the knob, the paddle is secured.

After the Flip Paddle is installed, simply push the paddle up and away from your field of vision.

D. Use of the Side Shields (titanium-framed loupes only):
Our loupes with titanium frames are packaged with transparent side shields for your protection and regulatory compliance. SV Sport frame models feature a wrap-around design that don’t require or include the side shields.
To install the side-shields:

  1. Identify whether the shield is left or right sided. The notch in the shield indicates the top.

  2. Place the shield over the narrow portion of the temple arm so that the two tabs above the side openings of the shield rest on the temple arm.

  3. Slide the shield gently toward the frame so that the front edge of the shield is snug against the frame.

  4. Repeat the procedure for the opposite arm.

This completes the installation of the side shields.

E. Loupe Cleaning Instructions:
Your loupes are precision instruments, and care must be taken when handling and cleaning the instrument. All loupes have lens coatings on the optics to enhance optical performance, and thus need to be cared for properly.


  • Immerse the loupes in water

  • Use any other disinfectant other than those recommended.

  • Sterilize with an autoclave, steam, gamma radiation, or use ultrasonics.

  • Use cotton balls to clean the optics – as they can scratch the lenses.


To further protect your lenses we recommend the use of the lens cap covers as noted above.

When cleaning the loupes we recommend that a two-step process be used. The first step is to remove gross debris and disinfect the loupes. Once disinfected then the loupes lenses can now be cleaned with an optical lens cleaner.
To clean:

1. First to remove gross debris, spray the loupes with a can of compressed air.

2. Then disinfect the loupes.

  • Wet a cotton swab with 70% isopropyl alcohol, mild soap, or Lysol I.C. (infection control) disinfectant.

  • Gently wipe the loupes to remove loose particles.

  • Wipe the loupes dry with a micro fiber cleaning cloth.

3. Finally, clean the lenses.

  • Use an optical lens cleaner formulated to clean coated-lens surfaces, or use the micro fiber cleaning cloth that was included with your loupes.

Finally, if you have any additional questions about cleaning your loupes, feel-free to contact our customer service department.
