How To Measure

Option 1: Measure an Existing Pair

  • Check the numbers printed inside your child’s current glasses (e.g. 46–16–130)
  • Match the lens width to the size range above

Option 2: Measure Face Width

  • Use a ruler to measure the distance between the temples
  • Compare with the total frame width listed on the product page

Fit Guide

A good fit should:

  • Sit comfortably on the nose without slipping
  • Align the eyes near the center of the lenses
  • Rest gently behind the ears with no pressure
  • Stay secure during normal play and movement

If between sizes:

  • 👉 Choose the larger size for growing room
  • 👉 Choose the smaller size for a snug, secure fit (recommended for sports)

Optician Tip

Children’s glasses should feel secure but never tight.
