Cleaning for Standard and Anti-Reflective Coated Lenses:

  • Rinse all dirt, dust and particles from lenses by running under a stream of warm water. Failure to rinse debris can result in lens scratches that cannot be removed.
  • Apply a drop of non gritty hand soap or dish soap to lenses and gently rub over the entire surface.
  • Rinse the lenses thoroughly under a stream of water, and wipe dry with a cloth.
  • Always store dry, eyewear, face-up in the included case to avoid scratches.

Eyeglasses Measurements

If you look carefully have a series of characters (numbers and letters) printed on them. These characters are the key to understanding more about the frame dimensions and proportions. Once you know what those obscure values and markings on the frame stand for, your next step is choosing a frame that is in proportion to your face and obviously fits you just right.

To begin with, there are four key measurements to consider.
While you might not always find this numbering sequence printed on your eyeglasses, retailers can easily hand over this information on request. KMI lists these specifications on the product page description as well.

  • Lens Width The first three values always appear in a sequence of three; 42-18-140/ a-b-c. The first character you will need is your frame width which is also the first and most important value in the series. Here, it would be 42. The frame width is the measurement of the lens in millimeters beginning from the left end piece to where the right end piece ends.
  • Bridge The bridge width is the second series of numbers in the sequence. The distance between the right lens and the left lens is what is referred to as the bridge. The bridge is the part of the eyeglasses that rests atop your nose.
  • Temple/Arm Length The temple length refers to the arms of the eyeglasses. The two arms that nestle behind your ears. This is the last numbering in the sequence and does not really vary much from one pair of eyeglasses to the other. For those who tend to end up with glasses that tip on one side; you might want to consider acetate temples which can be adjusted to fit your face snugly.
  • Lens Height – The vertical size is the height of the eyeglasses frame. It is measured from the top to the bottom of the lens aperture.
  • Total Frame Width – Your total lens width comprises of the left end piece plus the left lens which is held by the bridge and then joins the right lens and right end piece. Take a look at the illustration above. The most important measurement, with this measurement alone you can order correct frame.

Determining the right frame size for you.

Armed with this eyeglasses sizing guide, we hope it helps you zero in on right size for you.

  1. Stand in front of a mirror with a ruler held in line with your temple.
  2. Measure the distance between your temples as indicated in the illustration above
  3. To convert this measurement into a frame size :
    • Multiply your measured value by 25.4 for a size in mm or
    • Multiply your measured value by 10 for a size in cm
  4. The glasses are sized by a single lens width, the bridge and the temple. You are more concerned with the lens and bridge. Multiply the lens width by two (there are two lenses) and add the bridge width to get the overall width.
  5. Example using the photo above: for the width of 125mm shown a frame with a measurement of 55-15-135 would fit very well (55 x 2 + 15 = 125). If you find a frame that has a combination of  54-17-125, the overall width would be the same but allow more bridge width if you have a wider nose with slightly narrower lenses (1mm each).
  6. Your frame size can vary by +/- 3mm from your frame measurement

What is the right frame size for me?

Small (S)

The ideal frame width for narrow or small faces is <129mm

Medium (M)

Medium sized facial structures can wear frame widths of 130-139mm

Large (L)

Wider faces can opt for a frame width of >139mm


I know mine is a rare case but the temples of most glasses fall too short for me. Please help!   If you have a problem with temples being too short, try looking for frames with a temple length of 145 to 150mm. This will be different if you choose a semi-wrap or full wrap-around style frame where the temple arms are shorter due to the curvature of the lenses.

Where should the bridge rest?  Bridges that are in the same line as the brow line have a better appearance on those whose bridge of the nose is high. A bridge that is above your pupils is considered to be a high bridge. Frames with a lower bridge and a more arched brow line are ideally suited to faces with a low bridge or a bridge that is in line with the pupils or nearly so.

What is the right bridge width for me?

  • For close set eyes or those with a narrow bridge; 15mm to 17mm is ideal
  • People with wide set eyes or a wider bridge can wear 17mm to 22mm comfortably
