An infant’s Rx will typically be high-plus lenses. Frames must have comfort cable temples to wrap around the ear for security, since the infant will try to pull the glasses off. The cable should be long enough to encircle the ear lobe for proper grip. If the temple is too short the glasses may press into the face causing red marks or pressure at the bridge or ears. Since the bridge of an infants nose is not fully developed, the best-fitting frame in most cases is a plastic frame with a flat saddle bridge. This disperses the weight of the glasses evenly and allows the glasses to sit closer to the eyes. Nosepads on metal or plastic frames may break off or injure the infant. When adjusting, make sure the cable temples aren’t too tight. When the glasses are opened, the temples should be even and not skewed to one side. The temples when held to the side should also be angled somewhat even. If the right temple is angled too low the glasses will sit too high on the right side and conversely for the left side. Due to ears not being even, the temples should be adjusted to fit the individual with either pantoscopic or retroscopic tilt to balance the frame on the face. Polycarbonate or Trivex lenses are recommended, as they are the most impact-resistant.
