How Do You Measure the Width of Your Eyeglasses Frame?

To measure the width of your eyeglasses frame, you can follow a few simple steps. This involves checking the frame’s dimensions, typically indicated on the inner temple, and using a ruler to measure the distance between the lenses.

  1. Locate the frame size: Most eyeglasses have a size label printed on the inner side of the temples. Look for three numbers, usually separated by a dash. The first number represents the lens width, the second number denotes the bridge width, and the third number indicates the temple length. For example, a size may read 52-18-140, meaning the lens width is 52 mm, the bridge width is 18 mm, and the temple length is 140 mm.

  2. Measure lens width directly: If the size label is not available, take a ruler or a measuring tape. Place the ruler flat against the lens, measuring the horizontal distance across the widest part. Record this measurement in millimeters, as eyeglass sizes are generally standardized in that unit.

  3. Measure bridge width: The bridge is the part of the frame that sits on your nose. To find this measurement, measure the distance from the inside edge of one lens to the inside edge of the other lens at the bottom of the frame. Again, use millimeters for accuracy.

  4. Measure total frame width: To calculate the total width of the frame, add the lens width and bridge width together, then add twice the length of the temple arms (if measuring) to account for the entire frame. For example, if each lens is 50 mm wide, the bridge is 20 mm, and each temple arm is 140 mm, the total width would be 50 + 20 + (2 * 140) = 350 mm.

  5. Check your fit: When you have the measurements, you can compare them to different frame options. A proper fit will ensure comfort and effectiveness in vision correction. If you feel discomfort with your current pair, consider visiting an optician for professional assistance.

By using these basic steps, you can effectively determine if your eyeglasses frame has the right width for your needs.

  2. Neglecting temple length
  3. Ignoring frame width
  4. Failing to check bridge size

Understanding these points can significantly affect your eyeglasses fit and comfort.

  1. Not Considering Lens Size:
    Not considering lens size can lead to improper vision correction. Lens size refers to the diameter of the lenses, which affects how much of your field of vision is clear. If the lenses are too small, you may miss visual cues. Conversely, lenses that are too large can weigh down the frame and be uncomfortable. An ideal lens size varies by face shape and should be proportional to the width of your face. For instance, a study by the American Optometric Association highlights that wider frames provide greater peripheral vision, especially for individuals with larger pupils.

  2. Neglecting Temple Length:
    Neglecting temple length is another critical mistake. Temple length refers to the arms of the glasses that extend over the ears. If the temples are too short, they may not provide adequate support, leading to slippage. If they are too long, the glasses may slide off during movement. Opticians recommend measuring from the front of the frame at the temple hinge to the end of the temple. Standard temple lengths are typically 135mm, 140mm, and 145mm, according to the Vision Council’s Size Survey.

  3. Ignoring Frame Width:
    Ignoring frame width can also lead to poor fit. Frame width should match the width of your face to ensure comfort and effectiveness. If the frame is too narrow, it may pinch your temples, while an overly wide frame can leave gaps that allow light and wind to enter. The average frame width typically ranges from 122mm to 144mm. A study by the American Academy of Ophthalmology indicates that properly fitted frames can improve wearer comfort by 30%.

  4. Failing to Check Bridge Size:
    Failing to check bridge size often goes unnoticed. The bridge is the part of the frame that rests on the nose. An unsuitable bridge size can lead to discomfort and improper positioning of the lenses. A bridge that is too wide can cause the glasses to slide down, while a narrow bridge can pinch the nose. Understanding your bridge size helps achieve a balance in the fit, contributing to overall lens effectiveness.
