What angle should be matched to achieve the correct splay angle in pediatric fitting?

To achieve the correct splay angle in pediatric fittings, it is essential to match the splay angle of the lens to the splay angle of the child's eyes. The splay angle refers to the angle created between the upper and lower parts of the lens as it sits on the child's face. This angle is crucial in ensuring that the lenses provide optimal visual correction while ensuring comfort and proper alignment on the bridge of the nose.

Matching the splay angle helps accommodate the unique anatomical features of a child's face, which can differ significantly from those of adults. A proper splay angle ensures that lenses align well with the eyelids, allowing for maximum peripheral vision and comfort, particularly for young wearers who are still developing their habits of lens use. This careful consideration in fitting can greatly impact the effectiveness of the eyewear and the overall satisfaction of the child and their guardians.

The other angles—frontal, vertical, and crest—do not specifically address the requirement for achieving the right splay angle for pediatric fittings. This reinforces the importance of focusing on the unique anatomical needs of children in lens fittings.
